Characterization and preparation of eco-friendly foamed concrete using a foaming agent: Optimizing the design by Taguchi analysis

Solid waste management has emerged as the primary global environmental challenge due to the constant production of increasing waste by-products and materials. Using waste materials makes concrete production economical and helps resolve disposal problems. The effects of lightweight foam concrete reinforced with corncob ash (CA) and basalt fibre (BF) on durability, thermal conductivity, and mechanical properties are investigated elaborately in this study. The foam concrete mix is prepared in three series with a foam (F) content of 25, 50, and 75 kg/m3 with and without the CA and BF reference mixes. The mix of corncob ash is chosen as a cement replacement in six different concentrations: 0%, 20%, 30%, 40%, 50%, and 60%. In addition, compositions of 0.5%, 1.5%, and 3% basalt fibre length variation were incorporated into the weight of the cement. Split tensile, compressive, and flexural strengths are determined at 7, 14, and 28 days. The workability, porosity, durability, and thermal characteristics are also examined. This study analyses the confirmation experiment to verify the optimum mix proportions of lightweight foam concrete by applying Taguchi’s experimental design for concrete mixes incorporating by-products as a partial cement replacement. Adding BF improved the mechanical properties of compressive, tensile, and flexural strength, whereas adding CA decreased porosity and thermal conductivity. The 50% CA with 1.5% BF blended concrete with 50 kg/m3 F exhibits high strength compared to 25 and 75 kg/m3 at all ages. The split tensile strength of the F50CA50BF1.5 mix varies from 2.19 MPa to 2.73 MPa, and the compressive strength of 29.13 MPa is higher than that of 14.36 MPa, 18.63 MPa, and 0.88 MPa for the R 25, R 50, and R 75 kg/m3 mixes. The highest mechanical strength and improved durable properties are achieved by replacing 50% of CA and 1.5% of BF with F 50 by-products at all curing periods.

Magnesium phosphate cement-based engineered cementitious composites with polyethylene fibers: Performance improvement and design method

This study aims to improve the performance of magnesium phosphate cement-based engineered cementitious composites (MPC-ECC) and establish a systematic design method. The MPC-ECC with ultra-high ductility was prepared with the polyethylene (PE) fibers. The effect of the magnesium oxide to potassium dihydrogen phosphate mass ratio (M/P), quartz sand particle size (Sd), water to solid mass ratio (W/S), sand to binder mass ratio (S/B), fly ash (FA) content and fiber volume fraction (Vf) on the micro-mechanical properties and macro-mechanical properties of MPC-ECC were explored. The macro-mechanical properties of MPC-ECC with different curing temperatures and curing ages were also tested. And the SEM test was carried out to analyze the morphology of the MPC-ECC. The results showed that the ultimate tensile strain of MPC-ECC with optimal proportion can reach 7.1%. Even curing at −10 °C for 7 days, the ultimate tensile strain can reach 5.6%, and the compressive strength can reach nearly 20 MPa. And the microstructure is characterized by a highly dense morphology. Additionally, with the increase of M/P, the compressive strength of MPC-ECC increases, but the ultimate tensile stress decreases. The MPC-ECC with the Sd of 150–180 mesh shows significant strain hardening performance, and its ultimate tensile strain can exceed 5%. The large W/S is helpful to improve strain hardening performance, especially when the S/B is 0.2. In addition, when the FA content is 30% or 40%, the strain hardening performance of MPC-ECC is significant. The quantitative association model between ultimate tensile strain and pseudo strain-hardening indices was established. According to the association model, the design method of MPC-ECC was established, based on which the MPC-ECC with desired ductility can be realized. Meanwhile, the PSHσ and PSHJ are recommended to reach 2.15 and 25.1, respectively, at the same time for the MPC-ECC with ultimate tensile strain of above 3%.

Optimum Designs for Optimum Mixtures: An Informative Review

In a mixture experiment, the measured response is assumed to depend only on the relative proportions of ingredients or components present in the mixture. Scheffe´ (1958) first systematically considered this problem, and introduced different models and suitable designs. Optimum designs for the estimation of parameters in various mixture models are available in the literature. However, in a mixture experiment, interest is likely to be more on the optimum mixing proportions of the ingredients being used. In this exposition, we take the readers on a journey through the optimum designs developed for estimating the optimum mixture combination as accurately as possible under various mixture models.

Rheology of Superabsorbent Polymer-Modified and Basalt Fiber-Reinforced Cement Paste with Silica Fume: Response Surface Methodology

A composite's rheology can be changed by adding superabsorbent polymer (SAP) and basalt fibers and using silica fume. This study aimed to investigate the effects of these components on the viscosity and shear stress parameters of the paste. The proportions of the components were varied, with SAP content ranging from 0.01% to 0.03%, basalt fiber from 0% to 0.50%, silica fume (micro silica) at 15%, and water content from 0.40 to 0.50. Response surface methodology was used to optimize the mixture proportions, and the rheological properties of the resulting pastes were characterized using a rheometer. Results showed that the addition of SAP and basalt fiber had a significant impact on the rheological properties of the paste, with increasing amounts of both resulting in increased viscosity and shear stress. Overall, this study highlights the potential of SAP and basalt fiber in advances of the rheology of cement paste and provides insight into the optimal proportions of these components for achieving desired rheological properties. The findings of this study could be useful in developing high-performance concrete with enhanced rheological properties, which could have a wide range of applications in the construction industry. In addition, 0.50% BF, 0.01% SAP, and 0.445 water-to-cement were found as optimum proportions regarding the rheology of the cement paste.

Study on the shielding performance of bismuth oxide as a spent fuel dry storage container based on Monte Carlo simulation

For traditional spent fuel shielding materials, due to physical and chemical defects and cost constraints, they have been unable to meet the needs. Therefore, this paper carries out the first discussion on the application and performance of bismuth in neutron shielding by establishing Monte Carlo simulation on the neutron flux model of shielded spent fuel. Firstly, functional fillers such as bismuth oxide, lead oxide, boron oxide, gadolinium oxide and tungsten oxide are added to the matrices to compare the shielding rates of aluminum alloy matrix and silicone rubber matrix. The shielding rate of silicone rubber mixture is higher than aluminum alloy mixture, reaching more than 56%. The optimal addition proportion of bismuth oxide and lead oxide is 30%, and the neutron radiation protection efficiency reaches 60%. Then, the mass attenuation coefficients of bismuth oxide, lead oxide, boron oxide, gadolinium oxide and tungsten oxide in silicone rubber matrix are simulated with the change of functional fillers proportion and neutron energy. This simulation result shows that the mixture with functional fillers has good shielding performance for low energy neutrons, but poor shielding effect for high energy neutrons. Finally, in order to further evaluate the possibility of replacing lead oxide with bismuth oxide as shielding material, the half-value layers and various properties of bismuth oxide and lead oxide are compared. The results show that the shielding properties of bismuth oxide and lead oxide are basically the same, and the mechanical properties, heat resistance, radiation resistance and environmental protection of bismuth oxide are better than that of lead oxide. Therefore, in the case of neutron source strengths in the range of 0.01–6 MeV and secondary gamma rays produced below 2.5 MeV, bismuth can replace lead in neutron shielding applications.

Optimal Mix Design and Mechanical Properties of Rapid-Hardening Foam Concrete

This paper conducts compressive strength tests on foam concrete prepared under four factors and three levels through the design of orthogonal experiments. It delves into the phase change rules of the load–displacement curves obtained under various mix proportions. Furthermore, based on the 1-day and 3-day compressive strength values, the study explores different mix proportion results using range analysis and variance analysis methods, thereby determining the optimal mix proportion that can satisfy the maximum 1-day and 3-day compressive strength values. The results indicate that the compression process of rapid-hardening foam concrete includes four stages: initial compaction stage, elastic stage, yielding stage, and plateau stage, with each stage having different causes. Additionally, the sensitivity sequence of factors affecting the 1-day and 3-day compressive strength of rapid-hardening foam concrete is respectively rapid sulfoaluminate cement (α) > water-reducing agent content (δ) > foam content (β) > water-cement ratio (γ) and rapid sulfoaluminate cement (α) > water-cement ratio (γ) > foam content (β) > water-reducing agent content (δ). With 100% sulfoaluminate cement content, the 1-day and 3-day compressive strength values can reach 1.7054 and 2.5471 MPa, respectively, which are 13 times and 7 times the minimum values of 1-day and 3-day compressive strength under other admixtures. The analysis shows that the content of rapid sulfoaluminate cement has the most significant effect on the 1-day and 3-day compressive strength of rapid-hardening foam concrete, with foam content having the least impact on 1-day compressive strength and water-reducing agent content having the least impact on 3-day compressive strength. By integrating range analysis and variance analysis, the optimal mix proportion that simultaneously satisfies the maximum 1-day and 3-day compressive strength is determined to be 100% content of rapid-hardening sulfoaluminate cement, 4% foam content, 0.55% cement ratio, and 0.12% admixture content. Overall, this study provides theoretical support for the research and development of new rapid-hardening foam concrete materials and has significant practical implications for the emergency repair and construction of infrastructure projects.

NLC-Based Sunscreen Formulations with Optimized Proportion of Encapsulated and Free Filters Exhibit Enhanced UVA and UVB Photoprotection.

The topical use of sunscreens is recommended for avoiding the damaging effects of UV radiation. However, improvements are still needed in the existing products to enhance their photoprotection effectiveness and safety. This involves minimizing the use of chemical UV filters while providing enhanced and prolonged photoprotection. This work investigated novel sunscreen formulations and their UV protection effects by encapsulating Uvinul® A, Tinosorb® S, and Uvinul® T150 into nanostructured lipid carriers (NLCs) based on bacuri butter and raspberry seed oil. First, the impact of critical formulation and process parameters on NLCs' particle size was evaluated using a 22 Face Centered Central Composite Design. Then, formulations were evaluated in terms of critical quality factors, in vitro skin permeation, and in vitro and in vivo photoprotection activities. The developed NLCs-containing formulations exhibited appropriate size (122-135 nm), PdI (<0.3), encapsulation efficiency (>90%), and drug content (>80%), which were preserved for at least 90 days under different stability conditions. Moreover, these NLCs-based formulations had equivalent skin permeation to emulsion-based controls, and the addition of NLCs into sunscreen cream bases in the optimum proportion of 20% (w/w) resulted in enhanced UVA and UVB photoprotection levels, despite a 10% reduction in the total filters content. Altogether, these results describe the application of nanoencapsulated organic UV filters in innovative sunscreen formulations to achieve superior photoprotection and cosmeceutical properties.

Fired clay bricks synergistically valorizing hazardous nickel chrome-plating sludge and fly ash: Performance assessment

Nickel Chrome Plating Sludge (NCPS) is a hazardous waste containing 25%-30% nickel and chromium. Previous attempts to immobilize NCPS into fired clay bricks resulted in weakened strength due to porosity and microstructure deterioration. This study introduces co-valorization of NCPS and fly ash in fired clay bricks to address these issues. Factory-scale firing of green bricks, alongside conventional clay bricks, assessed the commercialization potential. The optimal proportion of NCPS, fly ash, and clay was found to be as 12.5:37.5:50.0, respectively. Fly ash addition significantly improved brick properties, causing compressive strength to increase from 3.2 MPa to 11.6 MPa for a NCPS content of 12.5%. Microstructural analysis highlighted fluxing oxides in NCPS, amorphous silica-alumina in fly ash, synergistic ceramic bond formation, enhanced sintering and pore filling during vitrification. The study also demonstrated substantial fuel savings of 40%-50% due to NCPS's high heat of combustion causing internal firing of green bricks. The developed bricks exhibited almost double linear attenuation coefficients, indicating enhanced gamma radiation shielding. Leaching tests confirmed successful heavy metal immobilization. This co-valorization approach not only overcomes previous drawbacks but also offers significant environmental and economic benefits in utilizing NCPS in brick production.

This study delves into the integration of phase change materials (PCM) in solar thermal collector systems to address this challenge. By incorporating nano encapsulated PCMs, researchers have mitigated concerns surrounding PCM leakage, revolutionizing the potential of solar collector systems to elevate energy efficiency, diminish carbon emissions, and yield manifold benefits. This article comprehensively investigates the design and utilization of solar phase change energy storage devices and examines the transformative impact of employing nano-coated phase change materials (Nano capsules) to augment solar collector performance. The integration of paraffin-based PCM and the insulation of the collector system have been crucial in optimizing heat retention and operational efficacy. The composition of the PCM involves a balanced blend of octadecane phase-change particles and water as the base fluid, designed to maximize thermal performance. Analysis of the experimental findings demonstrates the dynamic thermal behavior of the nano encapsulated phase change material, revealing distinctive temperature profiles about fluid dynamics and absorbent characteristics. Notably, the study emphasizes the nuanced trade-offs associated with the conductivity and melting temperature of the Nano encapsulated PCM, yielding valuable insights into energy storage capacity limitations and thermal performance variations throughout diurnal cycles. Central to the investigation, the optimal nanoparticle proportion is elucidated, shedding light on its pivotal role in modulating PCM performance. Furthermore, findings underscore the complex interplay between nanoparticle volume fraction and thermal fluid temperature, providing critical perspectives on optimizing PCM-enhanced solar collector systems.

Ultrasound-Assisted Multi-Enzyme Extraction for Highly Efficient Extraction of Polysaccharides from Ulva lactuca.

Ulva polysaccharides present several physiological activities including antiviral, antitumor and anti-plasmodial effects. However, current processing usually results in low yields and high prices, thus lacking commercialization potential. The aim of this study was to develop an efficient method for the extraction of Ulva polysaccharides with high biological activity. The effect of cell wall-degrading enzymes including cellulase, hemicellulase, pectinase and protease on Ulva polysaccharide extraction was studied by statistical mixing design. Using the most effective enzyme preparations as the basic components, the optimal proportions of the enzyme mixture were determined as follows: cellulase 35.3%, pectinase 34.5%, alkaline protease 30.2%, which increased the polysaccharide yield from 6.43% in the absence of enzymes to 26.68%. Subsequently, through response surface analysis, the optimal conditions were determined: enzyme concentration of 1.5%, enzymatic time of 1.1 h, ultrasonic time of 90 min and enzymatic temperature of 60 °C. Under the optimal extraction conditions, the extraction yield of Ulva polysaccharides could be increased to 30.14%. Moreover, extracted polysaccharides exhibit strong antioxidant properties in DPPH, ABTS, hydroxyl radical, superoxide radical and H2O2-induced cellular damage models. This study laid a solid foundation for the use and development of Ulva polysaccharides.

Potential of Pinewood Biochar as an Eco-Friendly Reducing Agent in Iron Ore Reduction.

This study investigated the optimal proportion of biochar derived from pinewood pellets (PW) and coke as reducing agents for the carbothermal reduction of iron ore at high temperatures. Thermogravimetric analysis, elemental analysis, X-ray fluorescence, and scanning electron microscopy were used to characterize the raw materials. To determine the effect of biochar proportion on reduction efficiency, presented as metallization, metallized pellets were subjected to chemical analysis, including total iron (T.Fe) analysis, metallic iron (M.Fe) analysis, and residual Fe2O3 and FeO analysis. The results indicated that the addition of biochar derived from PW, with coke as a reducing agent, considerably increased the efficiency of carbothermal reduction. Optimal reduction conditions were established at a reduction temperature of 1300 °C and a holding time of 20 min, with 20% coke and 80% pinewood char. In summary, biochar derived from PW can be used as an alternative to coke as a reducing agent in the iron reduction process. In addition, biomass can be used as a reducing agent to mitigate carbon consumption by reducing the amount of coke required in iron production.

Evolution of trust in the N-player trust game with the margin system

Investigations into trust behavior between investors and trustees using trust games have gained significant attention in recent years. However, understanding the process of trust evolution remains challenging. The margin system, widely employed in the financial industry as an economic and behavioral incentive mechanism, aims to maintain order in financial markets and protect participants' rights and interests. Despite its extensive use, the precise influence of the margin system on trust evolution dynamics remains unclear. To address this gap, we propose an N-player trust game model that incorporates a margin system within an infinite well-mixed population. In our model, a third-party institution collects a proportionate amount of margin from trustees, which is returned upon fulfilling their obligations but forfeited otherwise. By utilizing replicated dynamic equations, we find that implementing the margin system can establish a stable coexistence state between investors and trustworthy trustees, representing a significant advancement in trust evolution. Additionally, an intriguing finding arises from our observation of an inverted U-shaped relationship between the magnitude of the attraction domain for coexistence and the coefficient of the margin. This suggests that excessively high margin proportions can discourage trustees' participation, while excessively low proportions may fail to effectively deter dishonest behavior. Optimal margin proportions can effectively promote trust evolution.

The Potential of Glass Waste as Sand Replacement in Concrete Mix for 3DCP Technology

The global population generates millions of metric tons of glass waste annually, with only a small fraction being recycled, leaving the rest to accumulate in stockpiles. This underutilization of glass waste poses environmental concerns and a tremendous need to increase recycling efforts to address sustainability concerns in the construction industry. The construction industry has seen the emergence of 3D Construction Printing (3DCP) technology for innovative opportunities. However, current research in 3DCP predominantly focuses on conventional methods, which are not environmentally sustainable practices in concrete production. Therefore, the objectives of the study are to determine the optimal proportion of glass waste to be used as a sand replacement in 3DCP, to assess the resulting concrete's strength, and to seek the acceptance of glass waste as a viable sand replacement in 3DCP. The research conducts a quantitative approach by varying test levels of glass wase (0%, 10%, 15%, 20%, and 25%) as a partial substitute for sand in concrete mixtures. In addition, this study employs qualitative methods to gain the acceptance of construction industry players about glass waste as a sand replacement in 3DCP. The findings show the potential of glass waste as a sustainable material, reducing waste disposal costs, mitigating environmental pollution risks, and conserving valuable landfill space. In conclusion, this study contributes to the promotion of green concrete practices and aligns with the Sustainable Development Goals (SDG).

Development and performance verification of a water-retaining semi-flexible pavement material based on alkali-activated slag system incorporating superabsorbent polymers

Water-retaining semi-flexible pavement (WRSFP) can effectively mitigate the urban heat island (UHI) effect by reducing the pavement temperature through water evaporation. To reduce environmental impacts and enhance the water retaining capacity and mechanical properties of WRSFP, this paper investigated the effect of proportion of water-retaining grout (WRG) on workability of fresh WRG, compressive strength, flexural strength, and water absorption of hardened WRG based on alkali-activated slag (AAS) system. The optimal proportion of WRG was recommended. The microstructure of the hardened WRG was observed with a scanning electron microscope (SEM), which allowed for a better characterization and understanding of the degree of hydration and mechanical properties of WRG. The WRSFP specimens (WRSFP-20%, WRSFP-25% and WRSFP-30%) with different porosities of porous asphalt mixture (PAM) were tested for moisture susceptibility, rutting resistance and low-temperature cracking resistance. WRSFP-25% had the best moisture resistance and rutting resistance, and the worst low-temperature cracking resistance. The maximum difference of upper surface temperature between WRSFP and stone mastic asphalt (SMA), which is commonly used in pavement, was 13.3 °C. The time to reach 60 °C on the upper surface of WRSFP was 3.4 times longer than that of SMA, which showed an excellent cooling effect of WRSFP.

Molecular interactions by thermodynamic and computational molecular docking simulations of selected strawberry esters and pea protein isolate in an aqueous model system

The objective of this study was to determine the interactions between selected strawberry esters and pea protein isolate (PPI) in a protein-containing aqueous model system, utilizing modified ultrafiltration and equilibrium dialysis techniques. Strawberry esters, including ethyl butanoate, ethyl isopentanoate, ethyl hexanoate, and methyl anthranilate, demonstrated different binding parameters to the PPI. Overall flavor binding affinities (nK) of all esters decreased as the temperature increased from 5 °C to 25 °C. Among these compounds, ethyl hexanoate exhibited the highest affinity to PPI at 25 °C. Thermodynamic parameters revealed that all ester-PPI interactions were spontaneous and enthalpy-driven, primarily involving van der Waals forces or hydrogen bonding. In addition, computational molecular docking studies also identified alkyl hydrophobic interactions in ester-PPI complexes. These findings illustrated that understanding the interactions between esters and PPIs can assist in determining the optimal proportions of compounds for flavorings in high-protein beverages from pea protein.

Role of nonionic natural dispersing agent Acacia Concinna on the slurryability and stability of concentrated iron ore suspension

The present study examines the impacts of saponin, extracted from the fruits of Acacia Concinna, in its effectiveness as a dispersant and stabilizer during the pipeline conveyance of iron ore particles. The basic fundamental characteristics of iron ore, which comprises a majority of hematite and has a size of (≤75 µm), have been examined and characterized. Iron ore water slurry (IWS) rheological behavior has been investigated as a function of saponin doses, pH, particle concentration, and the shear rate-shear stress correlation. The change in zeta potential with pH is used to compute the isoelectric point of IWS. An appropriate mechanism has been presented to explicate the interaction between saponin and particles of Iron ore. The surface-modified particles exhibit improved dispersion characteristics in the aqueous solution due to the modification of electrostatic force that the surface charge on each particle causes. Investigation indicates that the optimal proportion of saponin had a significant favorable effect on the fluidity and stability of the suspension. The analysis of the economic impact of the dispersant has been conducted through the evaluation of slurry head loss and specific energy consumption (SEC) pertaining to the implementation of the IWS pipeline in its intended commercial application.

Mix proportion and microscopic characterization of coal-based solid waste backfill material based on response surface methodology and multi-objective decision-making

The mix proportion of multi-source coal-based solid waste (CSW) for underground backfilling affects transportation and support performance of backfill materials, and even the backfilling cost. In this study, the optimal mix proportion of desulfurization gypsum (DG), furnace bottom slag (FBS) and gasification fine slag (GFS) is determined by the Response Surface Methodology–Box Behnken Design (RSM-BBD). Then the fluidity, bleeding rate, 3-day strength, 7-day strength and preparation cost are evaluation indicators, the optimal mix proportion of backfill materials is determined by the multi-objective decision-making method (MDM). Finally, the microstructure of the backfill material with optimal mix proportion was studied by TGA, MIP, SEM–EDS and XRD. The results show that the mix proportion of CSW with the optimal comprehensive index is coal gangue (CG): coal fly ash (CFA): DG: FBS: GFS = 1:1.5:0.2:0.1:0.1, the mass concentration is 78%, and ordinary Portland cement (OPC)/CSW = 7.5%. The weight loss phenomenon of the backfill material with the optimal mix proportion occurs continuously during the heating process, mainly due to the evaporation of crystal water, structural water and hydroxyl water. There are dense narrow-necked pores in the backfill material, and the pore connectivity is poor. There is no hydration reaction occurs between CSW particles, and the strength increase of the backfill material mainly depends on the hydration reaction of cement. In ettringite, part of Al2O3 is replaced by SiO2, and part of CaSO4 is replaced by CaCO3. This study provides a reference for the engineering application of underground backfilling with multi-source CSW.

Preperation and Performance Comparision of Autoclaved Aerated Concrete by Using Ceramic and Glass Wastes Instead of Silica

This study aimed to produce autoclaved aerated concrete (AAC) by using glass and ceramic waste in 10%, 20%, 30%, 40%, and 50% proportions as a substitute material for quartzite, and samples were produced under low pressure and heat (2.3 bar and 135 ºC). The microstructural properties were investigated by employing scanning electron microscopy (SEM) analysis. Unit weight, porosity, water absorption, ultrasonic wave velocity, compressive strength, and thermal conductivity parameters were experimentally investigated and compared to a control sample produced without waste. Test results showed that waste addition leads to decreasing porosity, water absorption, and increasing unit weight. Additionally, uniaxial compressive strength, thermal conductivity, and ultrasonic wave velocity values were increased by adding waste. The test results showed that glass and ceramic waste can be used as a quartzite sand replacement in the production of AAC and the optimum replacement proportions for the waste materials was 10%.

Experimenting the influence of corncob ash on the mechanical strength of slag-based geopolymer concrete

Abstract The construction sector has been under growing public attention recently as one of the leading causes of climate change and its detrimental effects on local communities. In this regard, geopolymer concrete (GPC) has been proposed as a replacement for conventional concrete. Predicting the concrete’s strength before pouring is, therefore, quite useful. The mechanical strength of slag and corncob ash (SCA–GPC), a GPC made from slag and corncob ash, was predicted utilizing multi-expression programming (MEP). Modeling parameters’ relative importance was determined using sensitivity analysis. When estimating the compressive, flexural, and split tensile strengths of SCA–GPC with MEP, 0.95, 0.93, and 0.92 R 2-values were noted between the target and predicted results. The developed models were validated using statistical tests for error and efficiency. The sensitivity analysis revealed that within the mix proportions, the slag quantity (65%), curing age (25%), and fine aggregate (3.30%) quantity significantly influenced the mechanical strength of SCA–GPC. The MEP models result in distinct empirical equations for the strength characteristics of SCA–GPC, unlike Python-based models, which might aid industry and researchers worldwide in determining optimal mix design proportions, thus eliminating unneeded test repetitions in the laboratory.
