This study involves partially replacing coarse aggregate with marble waste products, and cement fly ash, in order to obtain the best results. aims determine how use of these products affects mechanical properties resulting concrete, which could have valuable implications for sustainable construction practices. Different samples were prepared by adding slurry powder, a combination concrete. The modulus elasticity Poisson’s ratio calculated, it was found that admixtures had lower moduli higher values than did conventional concrete mixture. Based on elastic constants E µ general modified mixtures, two structures are modelled each mixture simulated using ETABS Ultimate software evaluate compare practical applicability mixtures. Both envisaged buildings considered identical, having shear walls placed symmetrically. response structure analysed applying earthquake load, wind respective combinations according IS codes. storey displacement stiffness under lateral load determined. results showed comparable those indicate has several benefits, including improved workability, as well adequate strength durability, resistance deformation, compared

Focusing on sustainable development, the demand for alternative materials in concrete, especially Self-Compacting Concrete (SCC), has risen due to excessive cement usage and resulting CO2 emissions. As Compressive Strength (CS) is dominant among concrete properties, this research concentrates developing SCC by incorporating Rice Husk Ash (RHA) Marble Powder (MP) as filler replacements, respectively, while applying Machine Learning (ML) Deep (DL) techniques forecast CS of RHA/MP-based SCC. The further evaluates material characteristics, with a strong emphasis ML DL prediction. samples various mixed ratios were cast examined after 91 days collect data model application. In experimental technique, 133 gathered, was predicted using seven input factors (cement, RHA, MP, superplasticizer, coarse aggregate, fine water) an 80:20 ratio. Various algorithms, including linear regression, ridge lasso K-nearest neighbors (KNN), support vector machine (SVM), decision tree (DT), random forest (RF), boosting methods such gradient boost (GB), XG (XGB), adaptive (ADB) are employed, along technique backpropagation neural network (BPNN) different optimizer algorithms (Adam, SGD, RMSprop) predict validated evaluation parameters R-squared (R2), mean squared error (MSE), normalized root (NRMSE), absolute (MAE), percentage (MAPE). Comparatively, ensemble BPNN Adam RMSprop optimizers demonstrate high accuracy predicting outcomes, indicated their coefficient correlation R2 values low values.

In addressing the dual challenges of sustainable waste management and environmental conservation in construction industry, particularly disposal tire crumb rubber (CR) demand for eco-friendly building materials, this study explores a novel solution. It examines incorporation mineral additions—namely silica fume (SF), marble slurry powder (MSP), fly ash (FA)—as partial substitutes natural fine aggregates cement concrete. Through comprehensive testing seventeen concrete samples, reveals that specific mix R10S5M10F15 contained 10% as replacement aggregates, 5% fume, 15% replacements cement, not only achieves compressive split tensile strength comparable to control mix, while 90 days flexural was improved by 4.48%; credited SF’s pozzolanic action filler effects MSP FA, but also inclusion CR, reducing due material variations, enhances ductility improves resistance sulfate acid attacks, despite increasing water absorption. The primary goal research is investigate feasibility effectiveness using materials foster more practices. objectives include detailed assessment mechanical properties durability incorporating these aiming determine optimal proportions their effective utilization. This study’s novelty lies its analysis synergistic combining SF, MSP, FA concrete, contributing field offering alternative approach traditional formulations highlighting delicate balance required optimized performance.

Abstract Interest has grown in recycled cement powder waste’s application building projects as a workable, long-term solution to environmental issues. This work presents experimental results investigating the behaviour of plain and fibre-reinforced waste paste with different volume fraction percentages micro steel fibres (1% 2%), where densified silica partially replaces 10% cement. For each mix, superplasticiser water-cement ratios were maintained constant. The study involved number studies, including flow table inspections, Field emission scanning electron microscopy (FE-SEM) tests, energy dispersive X-ray (SEM–EDX) testing, compressive flexural strength assessments, dry density measurements, ultrasonic tests. These evaluations aimed analyse specimens’ mechanical physical characteristics thoroughly. showed that substituting fume (SF) for certain amount could improve cement’s properties. Using 2% micro-steel significantly affected paste’s strengths. Nevertheless, an investigation revealed inclusion resulted reduction amplitude sound waves decrease stagnation flow. SEM–EDX tests satisfactory adherence between SF. clarifies why adding SF causes increase.

Self-compacting concrete (SCC) has become increasingly popular due to its superior workability, segregation resistance, and compressive strength. As the traditional methods for strength prediction are costly time-intensive, this study explores machine learning (ML) techniques as efficient alternatives SCC prediction. Three state-of-the-art hybrid Adaptive Neuro-Fuzzy Inference System (ANFIS) models, optimised using Firefly Algorithm (FA), Particle Swarm Optimization (PSO) Genetic (GA). For purpose, a robust dataset of 366 instances 7 input parameters is taken from literature. After data analysis pre-processing, hyperparameters models tuned best-fit model tested on unforeseen data. ANFIS-FF stands out best-performing (RTR2 = 0.945 RTS2 0.9395) in both training testing phases, closely followed by ANFIS-GA. All outperform ANFIS model, outlining significance hybridisation, however, ANFIS-PSO lags behind other two models. The highlights importance integrating with metaheuristic algorithms tackling complex engineering problems like design optimal mix design, minimising material waste ensuring cost-effectiveness. It serves benchmark future research comparing hybridisation starting point ANFIS.
