Abstract

Concrete is a major material used in construction. It consists of cement, fine aggregate, coarse aggregate and water. Usually, the usage of river sand in our country is very large in the construction industry. Due to its vast use, the demand for fine aggregate is increasing day by day. Hence, it is time to find a suitable alternate to meet the demand. The paper uses two different alternatives available abundantly, Manufacturing sand (M-sand) and seashore sand, as full replacement for regular river sand. The seashore sand was tested for pH, EC, chloride, salt content, etc. M25concrete grade was used. Cube, cylinder and prism specimens were casted and tested for compressive strength, modulus of elasticity for concrete and flexural strength. In addition to this, durability test was also conducted. The results are tabulated and compared with the conventional concrete.


Description

Concrete is unique among major construction materials because it is designed specifically for civil engineering project. It plays a critical role in the design and construction of the nation’s infrastructure. More than 10 billion tons of concrete are consumed annually (Weiguo et al., 2017). Concrete is a composite and versatile material composed of granular materials like fine and coarse aggregates embedded in a matrix and bound together with cement or binder which fills the space between the particles and glues them together (Samuel et al., 2017). Almost three quarters of the volume of concrete are composed of high quality aggregate. There are many types of concretes available, created by varying the proportions of main ingredients.
