Compressive Strength of Concrete with Recycled

In this study, recycled glass is used to replace the natural fine aggregate in different mix proportions to obtain the optimum combination that will produce the highest strength. The control samples are Grade 30 ordinary Portland cement concrete (OPCC) containing natural sand and coarse aggregate. The recycled glass concretes contain 70% natural fine aggregate + 30% size 300 micron
