Study on the Engineering Properties of Lightweight Foamed Concrete Modified with Palm Stalk Fiber as an Additive

The escalation of agricultural waste in Malaysia has emerged as a significant focal point today. Agricultural trash is typically disposed of in landfills without regard for environmental considerations. Prior studies have demonstrated that highly reactive silica-containing debris can interact with calcium hydroxide in concrete, resulting in a thick microstructure. This study examines the possible application of palm stalk fibre (PSF) as an additive in lightweight foamed concrete (LFC) to enhance its engineering properties. The assessed engineering properties include compressive strength, flexural strength, splitting tensile strength, shrinkage and ultrasonic pulse velocity. Four distinct PSF percentages of 0.15, 0.30, 0.45 and 0.60 % were utilized as additions to the LFC mix. The findings indicated that incorporating 0.45 % PSF into LFC yielded optimal outcomes for compressive strength, flexural strength, splitting tensile strength, shrinkage and ultrasonic pulse velocity of LFC. The surface roughness of PSF enhances fiber-to-matrix interfacial bonding, since a rougher surface facilitates the interlocking of SBK fibre with the matrix within the LFC cementitious matrix.

A novel mechanistic model for predicting shrinkage kinetics in plant-based foods by integrating solid matrix mobility and viscoelasticity

Deformation during drying is a major physical change influencing drying kinetics and final product quality. Therefore, accurate prediction of shrinkage kinetics is essential for determining the optimal drying conditions for these foods. Shrinkage kinetics is greatly influenced by their structural mobility (rubbery-glassy transition) and viscoelastic properties. The current deformation models lack a comprehensive integration of structural mobility and viscoelasticity concepts, resulting in limitation in attaining insights on physiochemical state variations and viscoelastic stresses developed during drying. In order to overcome this limitation, this study proposes a novel mechanistic shrinkage model that combines solid matrix mobility-based shrinkage velocity and viscoelasticity consideration, incorporating variable mechanical properties to simulate deformation arising from moisture loss and pressure gradient respectively. Comparison between predicted drying kinetics and shrinkage evolution with experimental observation yielded close agreement, achieving low mean absolute error values. As the drying process progressed, a distinct anisotropic shrinkage pattern emerged, which is attributed to varied structural mobility based on temperature and moisture distribution across the food sample. Notably, shrinkage driven by moisture loss significantly outweighed that induced by pressure, exerting a predominant influence on overall volume change. Furthermore, the model demonstrated heightened sensitivity to water transport parameters compared to mechanical factors, which indicates the significance of moisture dynamics in shaping the drying process. Combined consideration of physiochemical changes and viscoelastic concept in the developed deformation model extends new possibility towards optimizing the drying process as well as quality aspect evaluation.

An experimental evaluation of the performance of concrete reinforced with recycled fibers made from waste plastic bottles

This study addressed the issue of recycling waste plastic bottles as recycled plastic fiber (RPF) into sustainable waste plastic fiber-reinforced concrete (WPFRC). Thus, the effects of different RPF lengths (30, 50, and 70 mm), widths (2, 4, and 6 mm), and contents (0.3, 0.45, and 0.6 vol%) on the performance of WPFRC were systematically evaluated through the laboratory test series of workability, fresh unit weight, compressive and flexural strengths, drying shrinkage, water absorption, and ultrasonic pulse velocity. Results indicated that the addition of RPF had a negligible effect on the fresh properties of the WPFRC mixtures, while significantly enhancing the load-bearing capacity and reducing drying shrinkage in the WPFRC specimens, particularly at early ages. Additionally, all WPFRC specimens exhibited low water absorption rates and high ultrasonic pulse velocities, indicating good quality and durability. Overall, the study found that an RPF content of 0.45% by volume, an RPF length of 70 mm, and an RPF width of 2 mm yielded the best performance for WPFRC. As a result, incorporating RPF into concrete fosters the development of strong, durable, and sustainable materials for green construction.

Mathematical Modelling of Heat and Mass Transfer during Jackfruit Drying Considering Shrinkage

Shrinkage is an obvious phenomenon that occurs when drying plant-based food materials, and it has a crucial influence on heat–mass transfer mechanisms, energy consumption in drying, and dried product quality. The present study aims to develop a theoretical shrinkage model considering the drying kinetics and shrinkage velocity approach during the convective drying of jackfruit. Since there is no theoretical model in the literature that considers the transfer process along with shrinkage phenomena for jackfruit drying, this work focuses on presenting the drying and shrinkage kinetics behaviour through the development of a mathematical model. Two distinct models were developed, each considering the presence or absence of shrinkage phenomena. Model validation was carried out by comparing the predicted results with experimental data from drying tests conducted at 60 °C, and model accuracy was evaluated through statistical error analysis. In the shrinkage-induced model, the shrinkage exhibited a linear relationship with drying time, as the moisture content decreased from 5.25 to 0.47 kg/kg on a dry basis when the temperature increased to 54 °C. Notably, the shrinkage-induced model demonstrated superior performance, displaying low mean absolute error (MAE) values—0.27 kg/kg on a dry basis for moisture content, 2.07 °C for temperature variation, and 0.04 for shrinkage, when compared to the model without shrinkage. Furthermore, the mean relative error (MRE) values for the shrinkage-induced model were 45.71% and 33.33% lower than those of the model without shrinkage for average moisture content and temperature, respectively. The findings of this study provide valuable insights for the food drying industry, offering new knowledge about drying kinetics and shrinkage characteristics that can contribute to the development of energy-efficient drying systems.

Durability Properties of Lightweight Foamed Concrete Reinforced With ‘Musa Acuminate’ Fibre

The demand for lightweight building materials that are easy to work with, self-compacting, and environmentally friendly has been acknowledged by the construction industry globally. Given this demand, it has been discovered that a recent innovative material, lightweight foamed concrete (LFC), may be able to reduce the weight of ordinary concrete. Besides, utilizing LFC with the addition of natural fibres is seen as a great effort to assist sustainability. Corrosion of reinforcing steel, which affects the behaviour and longevity of concrete buildings, is one of the most significant challenges in the construction of reinforced LFC. Therefore, the focus of this work is on identifying the possible application of Musa Acuminate fibre (MAF) in LFC. The intention of this study is to ascertain the durability characteristics of LFC with MAF. The cast has a low density of 550 kg/m3. We'll employ several volume fractions of MAF that are 0.15%, 0.30%, 0.45%, and 0.60%. The ability to absorb water, porosity, drying shrinkage and ultrasonic pulse velocity are the four criteria that will be evaluated. For the purpose of creating the necessary density of LFC, the protein-based foaming agent Noraite PA-1 was used. A constant water-to-cement ratio of 0.45 and a constant cement-to-sand ratio of 1.5 were used to get comparable results. The findings showed that for all of the durability attributes taken into account in this research, an increase of 0.45% MAF produced the best results. This resulted from the MAF and LFC cementitious composite's better bonding performance. Additionally, the fibres served as an anti-micro crack, preventing LFC cracks.

The use of inorganic ferrous–ferric oxide nanoparticles to improve fresh and durability properties of foamed concrete

Efforts to modify cement-based mixtures have continuously engrossed the interest of academics. Favourable impacts of nanoparticles, for instance, fine particle size and great reactivity, have made them be utilized in concrete. Foamed concrete (FC) is immensely porous, and its properties diminish with an increase in the number of pores. To enhance its properties, the FC matrix could be attuned by integrating numerous nanoparticles. The influence of ferrous–ferric oxide nanoparticles (FFO-NP) in FC was not discovered previously in the present body of knowledge. Thus, there is some uncertainty contemplating the mechanism to which extent the FFO-NP can affect the durability properties of FC. Hence, this study focuses on utilizing FFO-NP in the FC matrix. FC specimens with a density of 1000 kg/m3 were cast and tested. The objective was to assess the influence of different FFO-NP weight fractions (0.10%, 0.15%, 0.20%, 0.25%, 0.30%, and 0.35%) on durability properties such as drying shrinkage, porosity, water absorption and ultrasonic wave propagation velocity of FC. The results implied that the presence of a 0.25% weight fraction of FFO-NP in FC facilitates optimal water absorption, porosity, ultrasonic pulse velocity and drying shrinkage of FC. The presence of FFO-NP alters the microstructural of FC from loose needle-like into a dense cohesive microstructure of the cementitious composite. Besides, FFO-NP augments the FC matrix by filling the voids, microcracks, and spaces within the structure. Further than the ideal weight fraction of FFO-NP addition, the accretion of the FFO-NP was found, which caused a decline in durability properties.

Efficacy of Foamed Concrete Jacketing using Innovative Fibreglass Fabric for Durability Properties Improvement

This study intended to observe the effectiveness of foamed concrete jacketing using fibreglass fabric with the goal to enhance its durability properties. LFC of two densities of 500 kg/m3 and 1000 kg/m3 were cast and tested. The LFC specimens were wrapped with 1 layer, 2 layers and 3 layers of fibreglass fabric. The parameters evaluated were porosity, water absorption, drying shrinkage and ultrasonic pulse velocity. The results revealed that adding fibreglass fabric to LFC decreased its porosity and water absorption for both densities. Fibreglass fabric did more than only prevent cracks; it also reduced the drying shrinkage and increased the ultrasonic pulse velocity of LFC. Three layers of fibreglass fabric offered optimal results for all properties studied. As a result of the fibreglass fabric's ability to prevent moisture evaporation and consequent dimension changes in the confined LFC, drying shrinkage strain was kept least. The use of fibreglass fabric not only prevented water from escaping but also stopped it from penetrating the cement matrix. This preliminary study shows a huge potential to utilise fibreglass fabric as a strengthening medium to improve the durability performance of LFC.

Assessment of internal curing of cellulose microfibers-incorporated cement composites using destructive and nondestructive methods

Water-saturated cellulose microfibers (CMFs) incorporated into fresh cement composites can facilitate the internal curing, holding a potential for mitigating intrinsic material defects such as microcracks, interfacial transition zones (ITZs), and pores that raise the material nonlinearity. To elucidate the contribution of water supply from CMFs to internal curing process, this study utilizes the nonlinear impact resonance acoustic spectroscopy (NIRAS) technique. Hysteresis acoustic nonlinearity parameter (α) and linear resonance frequency are measured from the NIRAS tests and used to nondestructively quantify the microstructural changes induced by different degrees of internal curing in three different samples (with 0, 0.3, and 1% dosage of CMFs). To get more insight into this phenomenon, other properties including porosity, internal relative humidity (IRH), autogenous shrinkage, compressive strength, and ultrasonic wave velocity are also measured. Evidenced by all measured data, our results confirm that α shows a high sensitivity to the extent of microstructural change in cellulose microfibers-incorporated cement composites, which solely enables capturing time-dependent microstructural changes and thus the discrimination between internal curing effect and development of intrinsic material defects (or material nonlinearity). We believe that this study can lay the foundation for enhancing the durability performance of cement composites via CMFs.

The bulk generation of quarry dust (QD) from quarries, aggregates, and decorative stone plants, is a serious environmental issue. However, QD has the potential to provide eco-economic and technical merits when incorporated in the construction products. This review provides current investigations on the development of QD-based cementitious material. Constituent materials, preparation techniques, measurable attributes, and potential uses were all compiled in this study. The ongoing study must be expanded to encompass additional building applications and intensified in terms of processing methods and researched qualities. More specifically, this research reviews and discusses the findings of concrete fresh properties, such as workability, flowability, and setting time, as well as hardened concrete properties, such as compressive strength, split tensile strength, flexural strength, drying shrinkage, unit weight, mass loss and ultrasonic pulse velocity. Besides, durability properties were reviewed, such as water permeability, chloride permeability, water absorption, and acid attack. Further, an overview on the microstructure and thermal properties of QD concrete were provided. QD is useful in enhancing the workability of concrete. This paper covers recommendations and observations for future research.

Mechanical and Durability Properties of Foamed Concrete with the Addition of Oil Palm Trunk Fibre

Nowadays, in Malaysia, one of the country's challenges is the improper management and disposal of solid waste. The leading sector that generates most of the solid waste in Malaysia is the agricultural sector from oil palm fibre, similar to oil palm trunk fibre, which is also be used as an additive in producing foamed concrete (FC). However, FC presents a weakness in tension, which can be reduced by adding an adequate volume of waste biomass by-product such as oil palm trunk (OPT) fibre. Accordingly, this study was undertaken to investigate the potential of utilising OPT fibre as a reinforcement in FC. There were four different volume fractions of OPT fibre: 0.15%, 0.30%, 0.45%, and 0.60% used as an additive to the FC mix. Two densities, 600 kg/m3 and 1200 kg/m3, were cast and tested. All FC specimens were then prepared and left to cure and exposed to the elements for 7, 28, and 56 days. In this study, to properties were examined: mechanical and durability properties. The results showed that the addition of OPT fibre in FC improved the compressive strength, flexural strength, tensile strength, water absorption, drying shrinkage, porosity and ultrasonic pulse velocity of the FC. OPT's surface roughness was proved beneficial for fibre to matrix interfacial bonding since a coarser surface permit OPT fibre and matrix interlocking in the hardened cement matrix. Based on the results of this study for 600 kg/m3 density, 0.30% volume fraction was the optimum amount added to the FC to achieve the best durability and mechanical properties. While for 1200 kg/m3, 0.45% volume fraction of OPT was the optimum percentage.

Effect of using limestone fines on the chemical shrinkage of pastes and mortars.

The main aim of this study is to examine the effect of incorporating limestone fine (LF) on chemical shrinkage of pastes and mortars. For this purpose, five paste and five mortar mixes were prepared with 0, 5, 10, 15, and 20% (by weight) LF as a replacement of cement. The water-to-binder (w/b) ratio was 0.45 for all mixes. The sand-to-binder (s/b) ratio in the mortar mixes was 2. Testing included chemical shrinkage, compressive strength, density, and ultrasonic pulse velocity (UPV). Chemical shrinkage was tested each hour for the first 24h, and thereafter each 2days until a total period of 90days. Furthermore, compressive strength and UPV tests were conducted at 1 day, 7, 28, and 90 days of curing. The results show that the long-term chemical shrinkage of pastes was found to increase with the increase in LF content up to 15%. Beyond this level of replacement, the chemical shrinkage started to decrease. However, the chemical shrinkage for mortars increased with the increase in LF content up to 10% LF and a decrease was observed beyond this level. It was also noticed that compressive strength for pastes and mortars attained the highest value for mixes containing 10 and 15% LF. The trend in the UPV results is somewhat similar to those of strength. Density for pastes and mortars increased up to 15% LF followed by a decrease at 20% replacement level. Correlations between the various properties were conducted. It was found that an increase in chemical shrinkage led to an increase in compressive strength.

Stimulus of Raw Oil Palm Trunk (OPT) Fibre on Durability Properties of Lightweight Foamed Concrete

Lightweight Foamed Concrete (LFC) has gained a huge amount of attention because of its high flowability, low self-weight, lower use of aggregate, low strength, and its thermal insulation. Furthermore, LFC is an environmentally friendly material because of its minimal usage of aggregate and high potential to incorporate waste material such as fibre. This research was conducted to assess the potential utilisation of oil palm trunk (OPT) fibre strengthened LFC in terms of its durability. Two densities of 600kg/m3 and 1200kg/m3, were cast and tested with 4 different percentages of OPT fibre, which were 0.15%, 0.30%, 0.45% and 0.60%. The parameters evaluated were water absorption, porosity, drying shrinkage, ultrasonic pulse velocity. The results revealed that the inclusion of OPT in LFC helps to minimise water absorption and the porosity of LFC. Moreover, the inclusion of OPT also enhances the drying shrinkage and ultrasonic pulse velocity of LFC.

The effects of waste polyethylene terephthalate (PET) particles on the properties of fresh and hardened self-consolidating concrete

Self-compacting concrete (SCC) due to several economical and technical advantages is increasingly used in construction industry. It can be improved on strength behavior when the particles are added. Although the workability as a significant factor for this concrete must be maintained. This investigation experimentally evaluated the effects of PET (polyethylene terephthalate) particles on the properties of either fresh or hardened SCC. This particles resulting from cutting and pulverizing water and bavarage bottles and plastic bags. Fresh properties of SCC have been investigated by slump flow, V-funnel and L-box tests. Hardended properties were tested for compressive strength, splitting tensile strength, flexural strength, shrinkage and ultrasonic pulse velocity (UPV) tests on different ages. The results showed that 3 Kg/m3 PET particles can be considered as suitable contents regarding to fresh and hardened properties of SCC. However, the addition of PET particles have caused a slight decrease in compressive strength.

Utilisation of Oil Palm Fibre Biomass Waste as Additives in Foamed Concrete

Worldwide, the construction industry has acknowledged the future demand for lightweight construction materials, with high workability, self-compacting, and environmentally friendly. Given this demand, recent innovative material namely foamed concrete (FC), has been found to reduce normal concrete’s weight potentially. However, while FC made with Ordinary Portland Cement has good compressive strength, other characteristics such as tension are relatively weak given the number of micro-cracks. Therefore, the study focused on the potential use of oil palm fibres in FC regarding their durability and mechanical properties. Notably, one of the major issues faced in the construction of reinforced FC is the corrosion of reinforcing steel which affects the behaviour and durability of concrete structures. Hence, in this study, oil palm fibres were added to improve strength and effectively reduce corrosion. Five types of fibre generated from oil palm waste were considered: oil palm trunk, oil palm frond, oil palm mesocarp and empty fruit bunch consisting of the stalk and spikelets. Specimens with a density of 1800 kg/m3 were prepared in which the weight fraction of the fibre content was kept constant at 0.45% for each mixture. Testing ages differed in testing and evaluating the parameters such as compressive strength, flexural strength, tensile strength, porosity, water absorption, drying shrinkage and ultrasonic pulse velocity. The results showed that the incorporation of oil palm fibre in FC helped reduce water absorption, porosity and shrinkage while enhancing the compressive, flexural and tensile strength of FC.

The Effect of Raw Mesocarp Fibre Inclusion on the Durability Properties of Lightweight Foamed Concrete

Researchers around the globe have recognised the potential need for lightweight, reliable, easy to use, affordable, and even more sustainable building materials. One of the vanguard proposals has been the procurement, development and use of alternative, non-conventional local building materials, which includes the possibility of utilising lightweight foamed concrete (LFC). LFC is excellent under compression but poor in tensile stress, as it produces multiple microcracks. LFC cannot withstand the tensile stress induced by applied forces without additional reinforcing elements. This research was conducted to examine the potential utilisation of oil palm mesocarp fibre-reinforced (OPMF) LFC in terms of its durability. Two densities, 600 kg/m3 and 1,200 kg/m3, were cast and tested with five different percentages of OPMF, which were 0.00% (control), 0.15%, 0.30%, 0.45% and 0.60%. The parameters evaluated were water absorption, porosity, drying shrinkage, ultrasonic pulse velocity. The results revealed that the inclusion of OPMF in LFC helps to minimise water absorption and the porosity of LFC. Moreover, the inclusion of OPMF also improves the drying shrinkage and ultrasonic pulse velocity of LFC.

Possibility of using recycled waste medical-glass as fine aggregate in normal-strength concrete

The possibility of using recycled waste medical-glass aggregate (RGA) as a fine aggregate in the production of normal-strength concrete was investigated in this study. The influence of RGA as crushed sand (CS) replacement at different levels (by volume) of 0 – 100% (an interval of 20%) on the engineering properties and durability of concrete was also studied. Results show that the replacement of CS by RGA insignificantly affected the workability and unit weight of fresh concrete mixtures. Besides, using RGA to replace 20 – 60% CS was beneficial in terms of compressive strength, drying shrinkage, and ultrasonic pulse velocity (UPV). At these replacement levels, the dry density values were found to increase and the water absorption values were reduced as well. However, replacing CS with RGA up to 80% and 100% caused a reduction in compressive strength, dry density, and UPV and an increase in water absorption and drying shrinkage of concretes. Closed correlations among the above-mentioned concrete properties were also found in this study. All of the concrete samples obtained compressive strength values higher than the target strength (≥ 25 MPa) and they were classified as very good quality concretes with UPV values of above 4100 m/s. The experimental results demonstrate a high possibility of producing normal-strength concrete with a fine aggregate of RGA as either partially or fully replacement of CS. This also provides an environmentally-friendly solution for recycling waste medical glass in construction materials for sustainable development.

Valorization of Heat Treated Dredged Sludge in the Cement Matrix of Ordinary Concrete

The aim of this article is to propose a two environmental problems solution. One is the silting up of dams, despite the expensive dredging operations and the absence of a policy for the reuse of dredged sludge stored on non-agricultural land. The other represents the rate of cement used in the concrete. The dredged sludge is introduced after heating treatment at 600°C into the cement matrix of an ordinary concrete represents the proposed solution for both problems. In these eco-concretes, the cement has been replaced by treated dredged sludge at different percentages (5-10-20%) with a similar amount of water. Physical measurements and mechanical tests like shrinkage, absorption, and ultrasonic pulse velocity indicated dependence on substitution under dilution effect. Thermogravimetric analysis like the produced portlandite rate indicates a lack of reactive silica to supply the pozzolanic reaction. The results reveal that the substitution of 5% of cement by treated sludge leads to an appropriate concrete and minimizes the siltation effect.

00003 Volumetric assessment of cervical cancer tumor volume during definitive chemoradiation and the risk of early distant metastasis

ABSTRACT IMPACT: This study assesses patient and volumetric risk factors for distant recurrence within 6 months of completion of curative chemoradiation with brachytherapy in locally advanced cervical cancer. OBJECTIVES/GOALS: Initial tumor volume and tumor shrinkage velocity are prognostic of cure and survival after curative chemoradiation (CRT) for cervical cancer. We explored whether local tumor volumetric changes influence time to distant recurrences outside the radiation field. METHODS/STUDY POPULATION: We performed a retrospective cohort study of patients with FIGO Stage IB-IVA cervical cancer treated with curative CRT and brachytherapy at a tertiary academic center with minimum 3 months follow up and standard post-treatment FDG-PET. Patients received 6 weekly fractions of brachytherapy interdigitated with external beam radiation and cisplatin. Tumor volumes were assessed by MRI at brachytherapy planning. Patients who developed distant metastasis were classified as earliest (3-6 months), early (6-24 months) or late (>24 months) following completion of CRT. Absolute and percent decrease in tumor volume for each fraction were calculated with respect to first brachytherapy volume. Fisher’s exact and Mann Whitney-U tests were used for comparison of categorical and continuous variables. RESULTS/ANTICIPATED RESULTS: 143 of 574 (25%) patients developed distant metastasis. Distribution of age, histology, FIGO 2018 stage, primary tumor SUVmax, treatment length, and pre/post treatment squamous cell carcinoma antigen levels were not associated in each group. Para-aortic lymph metastases were more common in patients with earliest distant recurrence (33% earliest, 26% early, 12% late, p=0.03). Median initial tumor volume in the earliest (n=24), early (n =29) and late (n=9) groups was 57, 28 and 40 mL, respectively (p=0.08); 57 (earliest) vs 30mL (early+late groups), p=0.04. Average mid treatment (fraction 4) and end of treatment (fraction 6) percent shrinkage was 80 (earliest) vs 73 (early+late), p=0.84 and 94 vs 92, p=0.95, respectively. Neither absolute nor percent tumor shrinkage differed between early vs. late groups. DISCUSSION/SIGNIFICANCE OF FINDINGS: Tumor volumetric changes during definitive chemoradiation were not associated with the timing of developing distant metastasis, which is linked to presence of lymph node metastasis and tumor volume at diagnosis.

A Non-Isothermal Moving-Boundary Model for Continuous and Intermittent Drying of Pears.

A non-isothermal moving-boundary model for food dehydration, accounting for shrinkage and thermal effects, is proposed and applied to the analysis of intermittent dehydration in which air temperature, relative humidity, and velocity vary cyclically in time. The convection-diffusion heat transport equation, accounting for heat transfer, water evaporation, and shrinkage at the sample surface, is coupled to the convection-diffusion water transport equation. Volume shrinkage is not superimposed but predicted by the model through the introduction of a point-wise shrinkage velocity. Experimental dehydration curves, in continuous and intermittent conditions, are accurately predicted by the model with an effective water diffusivity that depends exclusively on the local temperature. The non-isothermal model is successfully applied to the large set of experimental data of continuous and intermittent drying of Rocha pears.

Influence of Barchip fiber on early-age autogenous shrinkage of high-strength concrete internally cured with super absorbent polymers

High-strength concrete (HSC) usually suffers the high early-age autogenous shrinkage owing to the low water-binder (w/b) ratio. Barchip fiber and super absorbent polymers (SAPs) have been utilized to reduce the autogenous shrinkage of HSC at early age. The relationship between autogenous shrinkage and ultrasonic velocity of internally cured high-strength concrete (ICC) reinforced with Barchip fiber was studied utilizing the non-contact shrinkage test. Experimental study and corresponding analysis demonstrated that: (1) the autogenous shrinkage and ultrasonic velocity of concrete decreased with the volume percentage of Barchip fiber increasing, and decreased with the addition of SAPs; (2) models for predicting early-age autogenous shrinkage strain and ultrasonic velocity of ICC reinforced with Barchip fiber considering the fiber volume percentage and age were proposed; (3) the model of early-age autogenous shrinkage strain based on the results of ultrasonic velocity at different ages and at 28 d with no addition of Barchip fiber was proposed; (4) the prediction model of early-age autogenous shrinkage strain of ICC reinforced with Barchip fiber based on the age-dependent parameter on ultrasonic velocity was proposed.
