Concrete is a hetrogeneous material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water.
Various tests such as cube test, split tensile test etc are performed on the concrete to assess its properties. These tests are done on a specially made specimen which may not represent the actual structure. These tests required pre-planning. The … Continued
Concrete is a heterogeneous and hardened mass obtained from a mixture of cement, sand, coarse aggregate and water, in a certain proportion. The grade of concrete varies greatly in accordance with the changing proportion of its constituent materials. The proportion … Continued
Ferrocement is a composite material of mortar and reinforcement such as light steel fabrics and meshes and is used to form thin section. Ferrocement is a form of reinforced mortar that is embedded with closely spaced multiple layers of wire … Continued
Polymer concrete is a type of concrete that replaces cement by polymer as a binder. Sometimes, the polymer is used in addition to Portland cement to form Polymer cement concrete (PCC) or Polymer Modified Concrete(PMC). Polymer concrete composites have a … Continued
The manufacturing of concrete is broadly carried in six steps, which when sequentially followed, will produce a properly proportioned and complete mixed concrete. Each step has its own significance on the contribution of different properties, in the finished product. Different … Continued
Textile Reinforced Concrete (TRC) is an innovative technology in concrete filed in which the steel reinforcement is replaced by textile reinforcement. These fibres are mesh-like structures made up of glass, polypropene, jute, carbon etc. Textile Reinforced Concrete is commonly used … Continued
Admixtures are defined as the chemicals which are added to the concrete other than cement, aggregate, and water to modify its properties during or before the mixing of concrete. The properties which are commonly modified are the rate of … Continued
Green concrete is concrete which is eco-friendly, uses less energy in its production and produces less carbon dioxide than ordinary concrete. When people hear green concrete, they associate it with the concrete that is coloured with green pigment. But Green … Continued
Foam concrete is a type of lightweight concrete. The density of the concrete can be reduced by introducing stable voids in hardened cement paste. The voids can be introduced by air or by gas. In this concrete, a foaming agent introduces … Continued
