Abstract
Concrete is a widely used material in the world. Fine aggregate is an essential component of concrete. The most commonly used fine aggregate is natural river or pit sand. The global consumption of natural sand is very high due to the extensive use of concrete. In particular, the demand of natural sand is quite high in developing countries owing to rapid infrastructural growth. Therefore, the construction industries of developing countries are in stress to identify alternative materials to lessen or eliminate the demand for natural sand. The aim objective of this experimental work consists in: • Substituting sand by granulated blast furnace slag. • Utilizing the waste material (steel slag) in an effective manner. The use of the method of substitution permits to improve the strength of the concrete, to increase the production of building materials and to protect the environment, it also gave an economic approach to the construction industry. The experimental results obtained show that the partial substitution of ordinary sand by slag gives better results compared with the ordinary concrete, but the full replacement of fine aggregates by slag products affect negatively the strength of concrete.
