The compressive strength of concrete depends on various factors. Since these parameters can be in a relatively wide range, it is difficult for predicting the behavior concrete. Therefore, to solve this problem, an advanced modeling needed. aim literature achieve ideal and flexible solution necessary develop new approaches. Artificial Neural Networks (ANNs) have evolved from theoretical method widely utilized technology by successful applications variety issues. Actually, ANNs are strong computing tool that provides right solutions problems use conventional methods. Inspired biological neural system, networks now used solving range complicated civil engineering. This study''s target evaluating performance developed African vulture optimization algorithm (DAVOA)-Elman (ENNs) considering different input self-compacting strength. Hence, once 8 again get as close possible prediction conditions laboratory, 140 entered improved version Elman input. According results, element network has lowest mean squares test error 7 28 days 100 repetitions. Further, both strengths, grid with Logsig-Purelin interlayer transfer function error, which determines optimal function. Moreover, results showed DAVOA reliable time cost savings high power desired characteristics. Also, 7-day 28-day strength, built 74.54 70.44% improvement over 8-parameter networks, respectively, directly affects effect. Further considered rate properties.

Abstract The degradation of concrete structures is significantly influenced by water penetration since serves as the primary vehicle for movement harmful compounds. process capillary absorption widely recognized a crucial indicator durability unsaturated concrete, it allows dangerous substances to enter composite material. capacity intricately linked its pore structure, inherently porous. main goal this work create an innovative predictive tool that assesses porosity analyzing components using machine-learning (ML) framework. Seven distinct batch design variables were included in generated database: fly ash, superplasticizer, water-to-binder ratio, curing time, ground granulated blast furnace slag, binder, and coarse-to-fine aggregate ratio. Four distant ML algorithms, including AdaBoost, linear regression (LR), decision tree (DT), support vector machine (SVM), are utilized infer generalization capabilities algorithms estimate accurately. RReliefF algorithm was implemented calculate significant features influencing porosity. This study concludes comparison alternative techniques, AdaBoost method demonstrated superior performance with R 2 score 0.914, followed SVM (0.870), DT (0.838), LR (0.763). results evaluation indicated binder possesses remarkable influence on concrete.

In recent years, various aspects of research related to pervious concrete (PC) have progressed rapidly, and it is necessary summarise generalise the latest results. This paper reviews compares raw materials concrete, examining elements such as porosity, permeability, mechanical properties, durability. According comparisons, we put forward an ideal aggregate model with Uneven Surface, which may reinforce properties. By summarising important issues aggregate, particle size, water–cement ratio, additives admixtures, mixing ratio design, moulding, other factors that affect new design methods are proposed. A effective stress based on continuous porosity Terzaghi developed fit principle better. Finally, by frontiers key need be addressed in future scientific raised.
