摘要

Overuse of cement and natural sand has damaging impacts on the environment and society. To solve this, manufactured sand can be used in place of natural sand and cement, together with pozzolanic materials—industrial waste byproducts such as metakaolin, GGBFS, silica fume, and fly ash. Therefore, the present study project covered in this article investigates the practicability of using crushed sand and pozzolana in place of cement in concrete. This will thus simultaneously address the protection of natural sand quarries and the widespread usage of pozzolanic materials. The main objective of this experimental study is to determine the flow properties of concrete that is produced by replacing natural sand with manufactured sand in a range of ratios, including 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%, and 20% cement replacement using pozzolanic materials. The slump, flow, compaction factor, and vee-bee test were all run. Slump, impact factor, flow, and vee-bee were investigated and compared with conventional concrete for the different concrete mix proportions in order to uncover new properties of the concrete. According to the study's findings, workability qualities diminish as the proportion of synthetic sand substituted for natural sand increases. The experimental values were used to create an ANN model. 20% of the results are used for testing purposes when designing the model flow, and the remaining 80% are used for instructing the ANN model. calculated by dividing the 25 input data values by 25. An accurate elastic prediction of the slump, impact factor, flow, and vee-bee of concrete mixed with natural fine aggregate in place of artificial sand and cement in industrial cementitious waste is provided by the results of the ANN model. The findings of this have a look at help to lessen the removal of non-renewable herbal recourses and the environmental effect of commercial waste by way of developing additional sustainable concrete.
