With a gradient of 5%, manufactured sands with fines contents of 0%, 5%, 10%, 15%, and 20% were blended to produce concrete samples. A river sand control mix was adopted to study the effect of different fines contents on the performance of C60 manufactured sand concrete after carbonization. The mix proportion is shown in Table 4. River sand can be used for making mortar and plastering. Mortar is a mixture of Sand, cement, and water commonly used in construction to hold bricks and stones together. The Sand can be used to form the base of mortar and combined with cement to create a strong and durable mortar. Additionally, river sand is also used for plastering walls.Exploring the Difference in M Sand and River Sand
