Abstract
The most often used building material worldwide is concrete. It is made by mixing water, coarse aggregate, binding ingredients, and fine aggregate in the right amounts. Because it provides a good sign of the general quality of the concrete and is very simple to test, particularly under uniaxial compression, concrete strength is a commonly examined attribute. Concrete’s compressive strength serves as the primary criterion for structural designs, and fine aggregate has a significant impact on compressive strength as well. The three samples used for this research—quarry dust, erosion-deposited sand, and borrow pit sand—were subjected to sieve analysis in order to compare the compressive strengths of concrete made with various types of fine aggregate. 36 cubes, twelve for each sample in the mix ratio of 1:2:4, were cast. The samples underwent a compressive strength test after curing for 7, 14, 21, and 28 days by complete submersion in water. With compressive strengths of 9.93N/mm2 for quarry dust sand, 9.03N/mm2 for borrow pit sand and 8.0N/mm2 for erosion deposited sand respectively, the concrete made with quarry dust had the maximum compressive strength, followed by that made with borrow pit sand and erosion-deposited sand. It is recommended that quarry dust is considered suitable out of the samples tested for concrete production based on this research findings.
