Study on the use of CO2 to strengthen recycled aggregates and pervious concrete

Recycled aggregates (RA) are crushed materials derived from waste concrete or construction debris that play a crucial role in the recycling of construction waste resources. However, RA's irregular particle shape and surface cement paste adhesions limit its potential in pervious concrete applications. To overcome this limitation, the use of carbonation treatment methods to process RA and produce recycled aggregate pervious concrete (RAPC) was investigated. RA was subjected to a pre-carbonation treatment, followed by the production of RAPC mixtures using three slurry-to-aggregate ratios, carbonation curing, and two-step carbonation strengthening, which enhanced the physical and mechanical properties of the specimens. Then, the measurements including permeability coefficient, connected pore fraction, splitting tensile strength, and CT microstructure analysis were performed. A carbon footprint accounting system from "cradle to gate" was conducted to assess the specimens. Our results highlight that an increase in the slurry-to-aggregate ratio in RAPC mixtures results in enhanced mechanical properties but negatively affects permeability performance. By pre-carbonating RA, we significantly increase the pervious concrete's splitting tensile strength, up to 100%, and maintain the compactability while ensuring permeability performance (maximum 3.91% reduction for specimens with slurry-to-aggregate ratio of 0.3). The carbonation treatment method used in our study has ideal environmental effects, as it theoretically sequesters up to 58.12% of the total carbon emissions produced during the production process.

Characterizing the behavior of blended concrete incorporating metakaolin and quarry dust: an experimental investigation

Purpose This study aims to characterize the behavior of blended concrete, including metakaolin (MK) and quarry dust (QD), as supplementary cementing materials. The study focuses on evaluating the effects of these materials on the fresh and hardened properties of concrete. Design/methodology/approach MK, a pozzolanic material, and QD, a fine aggregate by-product, are potentially sustainable alternatives for enhancing concrete performance and reducing environmental impact. The addition of different percentages of MK enhances the pozzolanic reaction, resulting in improved strength development. Furthermore, the optimum dosage of MK, mixed with QD, and mechanical properties like compressive, flexural and split tensile strength of concrete were evaluated to investigate the synergetic effect of MK and quarry dust for M20-grade concrete. Findings The results reveal the influence of metakaolin and QD on the overall performance of blended concrete. Cost analysis showed that the optimum mix can reduce the 7%–8% overall cost of the materials for M20-grade concrete. Energy analysis showed that the optimum mix can reduce 7%–8% energy consumption. Originality/value The effective utilization is determined with the help of the analytical hierarchy process method to find an optimal solution among the selected criteria. According to the AHP analysis, the optimum content of MK and quarry dust is 12% and 16%, respectively, performing best among all other trial mixes.

Flexural and split tensile strength of concrete with basalt fiber: An experimental and computational analysis

The objective of this study is to create comprehensive multiscale models for predicting the split tensile strength (STS) and flexural strength (FS) of basalt fiber-reinforced concrete, with the intention of its use in the construction industry. To meet this objective, STS and FS data were collected from various academic research investigations. The collected data was further expanded by experimentally analyzing the FS and STS of basalt fiber (0.1 %, 0.2 %, 0.3 %, and 0.4 % by volume)-loaded concrete. The experimental investigation shows FS and STS increased with basalt fiber loading. The highest FS was 5.11 MPa (0.4 % basalt fiber), and the highest STS was 2.24 MPa (0.3 % basalt fiber). The collected STS (114 data) and FS (103 data) datasets were statistically examined and modelled using soft computing techniques. Seven soft computing techniques, namely Random Forest (RF), Stochastic Random Forest (Stochastic-RF), Random Tree (RT), Stochastic Random Tree (Stochastic-RT), Bagging Random Forest (Bagging-RF), Bagging Random Tree (Bagging-RT) and Artificial Neural Network (ANN) were used to predict the FS and STS of basalt fiber-reinforced concrete using nine inputs and two outputs. The accuracy of the models was evaluated using comprehensive measure (COM), correlation coefficient (CC), mean absolute error (MAE), root relative squared error (RRSE), relative absolute error (RAE), Nash-Sutcliffe efficiency (NSE), and root mean square error (RMSE). The Stochastic-RT model had better predictive ability for FS, as seen by its lowest COM value of 0.121, and optimal values for CC, MAE, RRSE, NSE, RAE, and RMSE. Conversely, with a minimal COM value of 0.0279, the Bagging-RT model showed better accuracy in predicting the STS of concrete. Furthermore, sensitivity analysis revealed that basalt fiber length has the most significant effect on FS prediction, whereas curing time is the most crucial element influencing the STS of the concrete.

Performance Analysis of Self-Compacting Concrete with Use of Artificial Aggregate and Partial Replacement of Cement by Fly Ash

Artificial aggregate (AF), i.e., silico manganese (SiMn) slag aggregate, is a byproduct of ferromanganese and silico manganese alloy production. The utilization of industrial waste and industrial byproducts in construction has increased the aim of conserving natural resources to nurture a pollution-free environment. The current study examines the performance of the use of artificial aggregate (AF) and partial replacement of cement with fly ash (FA). The properties of fresh concrete, as well as the compressive and flexural strength and split tensile strength of concrete were evaluated. Seven mix proportions were prepared for M30-grade concrete. The first was a control mix (with 0% AF and FA), three other mixes contained varying amounts of AF (20%, 40%, and 60%) as a partial replacement of CA with AF. The average compressive strength of the control SCC was found to be 32.87 MPa (megapascals) at the age of 28 days, and after replacing 20% natural aggregate with artificial aggregate, the compressive strength increased by 8.27%, whereas for 40% and 60% replacement, it decreased by 4.46% and 12.55%, respectively. Further investigation was performed on the optimum value obtained by replacing 20% of CA with AF. At this percentage, cement was replaced by FA at (15%, 25%, and 35%) where at 15%, the average compressive strength increased by 7.41%, whereas for 25% and 35% replacement, it decreased by 7.47% and 17.19%, respectively. For SCAF20 and SCF15, all strengths were at maximum due to the increase in its density. The findings show that the development of advanced construction materials is environmentally sustainable.

Utilization of Rice Field Conch Shells as a partial substitution of Cement and Fine Aggregate for Split Tensile Strength of Concrete

Aceh is one of the provinces in Indonesia which has a very large area of rice field production. However, there are many pests that hinder agriculture in Indonesia. One of them is the rice field conch shells which has the potential to cause very high losses to the rice crop harvest. The aim of this research was to determine the ratio of the split tensile strength of concrete using rice field conch shells as a partial replacement for cement and fine sand against normal concrete by 0%, 5%, 10%, and 15%. In addition, it was also seen the effect of immersing concrete specimens using rice field conch shells substitution in tap water and water collected from paddy's farm. This study used the ACI (American Concrete Institute) 211.1-91 and ASTM (American Society for Testing and Materials) methods. The specimens consisted of cylinders with dimensions of 15 cm x 30 cm, totaling 40 specimens with a design concrete compressive strength of 17.00 MPa. The curing of the specimens was carried out using tap water and water collected from paddy's farm for 28 days in the soaking tub. The results showed that 5% substitution of rice field conch shells in cement and fine sand using the tap water immersion method showed a 3% increase in the tensile strength of concrete in comparison with normal concrete. Meanwhile, immersion using the water collected from paddy’s farm method showed a decrease in the value of the split tensile strength of the concrete.

Plastic Coarse Aggregates with Low- and High-Density Polyethylene with Improved Shore Durometer Hardness as Partial Replacement to Natural Coarse Aggregates

One of the issues in engineering field is the massive demand of natural aggregates in building, which in some areas causes shortages in supplies. While globally, increasing production and consumption of plastic, which takes decades to decompose, is among the main issues that humanity is now experiencing as the world progresses. In this study, plastics with improved Shore Durometer hardness was looked into as a partial substitution for natural coarse aggregates (NCA) in solving these problems. The LDPE/HDPE plastic coarse aggregates were developed using the best ratio of LDPE and HDPE plastics by melting, molding, and forming into 5mm, 10mm, and 15mm cubes. The gravel substitution volumetric were 2.5%, 5.0%, 7.5%, and 10.0% of the concrete mixture, respectively. When the density of concrete, compression, flexure, and split tensile strength of concrete were examined, a 5% replacement with 10mm size produced the best results. A lighter-weight concrete is evident between the controlled sample and the experimental sample when the best size configuration and percentage replacement leading to a 2.97% difference. In general, the compressive strength and flexural strength of (plastic coarse aggregate) PCA-based specimen is 20.23% and 3.78% higher than that of the controlled specimen, respectively. However, it was found that the split-tensile was lower than the controlled specimen by 2.72%.

Preparation of carbon fiber conductive concrete and study on its mechanical and heating properties

Carbon fiber conductive concrete demonstrates great potential for effectively removing ice and snow from road surfaces. This study investigates the electrical conductivity and electromagnetic heating effects of carbon fiber conductive concrete, considering different carbon fiber dosages and temperatures. Experimental and numerical simulation methods were employed to assess the material's performance. The results show that as the carbon fiber content increases to 0.38 % and 1.5 %, the compressive strength decreases by 19 % and 55 %, respectively, which is related to the introduction of more bubbles and the agglomeration of carbon fiber when the carbon fiber is added, making it easier to produce stress concentration when the concrete is compressed. However, when the content of carbon fiber is small, the tensile properties of carbon fiber itself can improve the overall splitting tensile strength of concrete. With the increase of carbon fiber content, carbon fiber gradually forms a conductive network in the concrete, and the overall resistivity of the concrete decreases, but there is a certain threshold. Overall, 0.75 % fiber is the best solution. In addition, the heating process is accurately simulated by numerical simulation method. The simulation results are in good agreement with the experimental results, showing that the heating rate decreases with the increase of energizing time until reaching the heat equilibrium state. And the precise temperature distribution and change process that can be obtained through simulation provides valuable insights for engineering design.

Treated Waste Tire Using Cement Coating as Coarse Aggregate in the Production of Sustainable Green Concrete

Waste tire rubber is one of the most concerning environmental pollution issues. With the increasing demand for automobile production, the rate of waste tire generation has also increased. However, these tires often end up stockpiled and not properly disposed of. This non-biodegradable waste poses severe fire, environmental, and health risks. Due to the progressively severe environmental problems caused by the disposal of waste tires, the feasibility of using such elastic waste materials as an alternative to natural aggregates has become a research topic. The main objective of this research is to investigate the changes in the mechanical and durability properties of concrete with the inclusion of waste tire rubber at specific contents. A total of 80 cylinders measuring 100 mm × 200 mm were cast with waste tire aggregate as a partial replacement for natural coarse aggregate (5% and 10% by weight of natural coarse aggregate). A surface treatment of tire aggregate using a cement coating was performed to study its effect on concrete properties. This research indicates a noticeable reduction in the compressive and split tensile strength of concrete containing untreated waste tire rubber compared to normal concrete made with natural aggregates. However, an improvement was observed when the surface of tire aggregates was coated with cement grout. Additionally, it was noted that the slump value, water absorption, and porosity increased as the percentage of rubber increased. Nevertheless, unlike normal concrete, the failure pattern in tire-mixed concrete occurs gently and uniformly, indicating ductile behavior.

The effect of variation in the length of water hyacinth fiber twisted on split tensile strength high performance fiber concrete

One of the weaknesses of concrete is that it has a very small tensile strength, which makes it brittle. Normal concrete has a tensile strength of 9-15% of its compressive strength. To increase the tensile strength of concrete, it is necessary to add fiber. The types of fibers that can be used in concrete can be either natural fibers or non-natural fibers. Various alternatives can be made as an effort to improve the quality of concrete. One of them is by utilizing weeds or weeds into useful materials. One of these disturbing plants is the water hyacinth plant, which is quite abundant and grows very fast. Water hyacinth plants consist of stems, leaf petals, which are rich in fiber, which allows it to be used as an alternative additive in concrete mixtures for construction. The purpose of this research is to try to apply water hyacinth fiber (SEG) 0,75% in high performance concrete (HPC) to determine the effect of the ratio of water hyacinth fiber twisted length on the compressive strength and split tensile strength of high performance concrete with several variants fiber lengths of 2 cm, 1,5 cm and 1 cm. The results showed that the decrease in the compressive strength of water hyacinth fiber-rolled concrete for variations of 2 cm, 1,5 cm and 1 cm were respectively 10,76%, 14,16%, and 18,76% of the reference concrete compressive strength of 45,42 MPa and the highest splitting tensile strength of concrete is in the 1 cm fiber length variation of 3,65 MPa which is 9.89% of the concrete compressive strength of 36,90 MPa. The modulus value decreases with the variation in the length of the fiber strand.

Experimental Study on Partial Replacement of Cement with Nano Silica

Cement is a building material made by grinding calcined limestone and clay to a fine powder, which can be mixed with water and poured to set as a solid mass. However it is expected that the use of Nano-silica in concrete improve the strength properties of concrete.

Prediction of the Mechanical Properties of Fibre-Reinforced Quarry Dust Concrete Using Response Surface and Artificial Neural Network Techniques

The focus of this study is to forecast the 28-day compressive strength and split tensile strength of concrete with various percentages of jute and coconut fibres mixed with quarry dust. The response surface methodology (RSM) and the artificial neural networks (ANN) methods were adopted for 3 variable process modelling (coconut fibres of 0% to 2.5%, jute fibres of 0% to 2.5%, and quarry dust of 0% to 25% by weight of cement). The RSM Box−Behnken design (BBD) method was adopted to design the experiments. Test results showed that compressive strength of 34.6 N/mm2 was obtained for concrete with 0% jute, 0% coir, and 12.5% quarry dust. Similarly, the maximum split tensile strength of 3.8 N/mm2 was obtained for concrete with 1.25% jute fibres, 1.25% coconut fibres, and 12.5% quarry dust. ANOVA and Pareto charts were used to assess regression models for response data. Each progression variable’s statistical significance was assessed, and the resulting models were expressed as second-order polynomial equations. Levenberg−Marquardt (LM) algorithm with feed-forward back propagation neural network was used for assessing the compressive strength and split tensile strength of concrete. The statistical data, root mean square error (RMSE), mean absolute error (MAE), mean absolute and percentage error (MAPE), and determination coefficient (R2) show that both techniques, ANN and RSM, are effective tools for predicting compressive strength and split tensile strength. Furthermore, RSM and ANN models have a high correlation with experimental data. However, the response surface methodology model is more accurate.

Review on effect of graphene reinforcement on properties of cement concrete

Climate change has a negative impact on the mechanical characteristics of concrete in recent decades. The conventional concrete production contributed to carbon footprint on a large scale. Many researchers have started to investigate the new eco-friendly concrete materials. Graphene gives a number of excellent properties, such as high flexibility, Young’s modulus (E) = 1000000 N/mm2, tensile strength = 130000 N/mm2 and titled as material of the 21st century. This paper reviews the effect of graphene reinforcement to improve properties of cement concrete. The SEM images of graphene oxide (GO), reduced graphene oxide (rGO), graphene nanoplatelet (GNP) are studied with suitable preparation methods. The effect of these carbon based nanomaterials to improve the compressive strength and tensile strength of similar proportion concrete is worked out. The GO and rGO are proved to be effective in improving compressive strength and split tensile strength of concrete of similar mix proportion. The optimum dosage for GO lies in between 0.06 and 0.08 %, while for reduced graphene oxide (rGO) is 0.5 %, at which both strengths increase considerably. GNP does not contribute to increasing compressive strength and tensile strength of concrete but helps in pore structure enhancement. It reduces the mean, median, critical pore and void diameter effectively, which is designated as the nano-filler and segmentation effect of GNP.
