Reduction of cement content using graded aggregates in concrete production

The aim of this project was to reduce cement content in concrete mixtures by changing the aggregate grading. For purpose, were made with aggregates having different shapes, textures, and However, workability mix depends on its paste volume, composition, type used. Concrete testing performed, properties including slump, compressive strength, tensile splitting test tested. effect shape evaluated comparing one combination another. It found that S/A= 0.4 GR-B-CA+NA-A-FA had optimum generally, consistently highest workability, as well volume demand. This can be attributed poor grading a result gaps GR-B-CA content. Compared NA-A-CA + NA-A-FA, it resulted lower
