Keywords: manufactured sand; concrete; artificial neural networks 1. Introduction In many countries sources of natural sand for use as an aggregate in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging [1–3]. This is driving the need to source alternative aggregates, such as those from construction and demolition waste. One possible

Effect of Usage of Admixture in Concrete

Concrete consists of cement, sand, aggregate and water. Anything other than these if added in concrete either before or during mixing to alter the properties to our desired requirement are termed as admixtures. The use of admixtures offers certain beneficial effects to concrete like improved workability, acceleration or retardation of setting time, reduce water cement ratio, and so on.

What Is Admixture Types of Admixtures

Gas forming Admixture is also used to prepare lightweight concrete. For purposes of resistance to settlement and bleeding, a small amount of gas-forming Admixture is used, which is generally 0.5 to 2% by weight of cement. However, in order to manufacture light concrete in greater quantity generally, 100 grams per bag of cement is recommended.

Use of Manufactured Sand in Concrete Pavement

Selected manufactured sands can be used as part of the fine aggregates to deliver workable concrete for general applications and to provide good skid and abrasion resistance to concrete pavement. In concrete pavement, it was found that the use of free silica limit in the selection of natural sand to provide good skid resistance to concrete pavement does not necessarily apply to manufactured sands. CCAA research has found a sand
