3. Uses of River Sand in Construction. River sand finds extensive use in a wide range of construction activities. Some common applications include: 1. Concrete Production. River sand is a key ingredient in concrete production, serving as a fine aggregate that binds with cement, water, and other additives to form a solid and durable construction ...
Abstract This study compared the physical and mechanical properties of river sand concrete with quarry dust concrete. The constituent materials were batched by weight. The water-cement ratio and mix ratio selected for the experimental investigation were 0.55 and 1:2:4, respectively. The specimens were cured for 7, 14, 21 and 28 days. Slump, density and compressive …
