What is M40 Concrete Strength with Quarry Dust about?

The study investigated replacing natural river sand with manufactured sand in M40 grade concrete mixes at replacement levels of 0-100% to evaluate the impact on compressive strength. Concrete specimens with full replacement of river sand with manufactured sand and a super plasticizer dosage of 0.5% exhibited compressive strengths 9.5-10.45% higher than conventional concrete mixes at 7, 14, and 28 days. The study also found that workability of concrete with manufactured sand was improved with super plasticiz
