What is Concrete? Types of Concrete? Concrete Technology, Different types of notes about concrete are discussed in this website
What is Polymer Concrete The conventional concrete is porous due to air voids, water voids, or the inherent porosity of the gel structure itself. On account of the porosity, the strength of concrete is naturally reduced. The process like vibration, pressure application, etc. is generally adopted to reduce porosity, But none of these methods could…

High-Performance Concrete (HPC) The term High-Performance concrete is used for the concrete mixture which possesses workability, high strength, high modulus of elasticity, high density, high dimensional stability, low permeability and resistance to chemical attack. High-performance concrete contains the following ingredients: a) Good quality of aggregates b) Ordinary Portland cement or rapid hardening Portland cement at…
High-Density Concrete The concrete whose density varies from 3360 to 3840 kg/m3 is known as high-density concrete. However, they can be produced with densities up to 5280 kg/m3 using iron both fine and coarse aggregates. The high-density concrete is produced using aggregates having a specific gravity of more than 3.5. The commercially used aggregates are…
What is Lightweight Concrete? The conventional concrete is a heavy material having a density of about 2400 kg/ m３, and high thermal conductivity. Thus the dead weight of the structure made with ordinary concrete becomes large which ultimately makes the structure uneconomical. The concrete whose density varies from 300 to 1800 kg / m３ is known as…

Air Entrained Concrete Air-entrained concrete is made by mixing a small quantity of air-entrained agents or using air-entrained cement. These air-entraining agents produce non-coalescing air bubbles. These air bubbles act as flexible ball bearings and modify the properties of plastic concrete (such as workability, segregation, bleeding and finishing quality. It also modifies the properties…
Advantages of quality control of concrete The general feeling is that quality control involves extra cost, this is certainly not so. The advantages of quality control offset the extra cost. Some of the advantages of quality control of concrete are described below. 1) Quality control of concrete assures rational use of available resources and thus…

Quality control of concrete Concrete is generally produced in batches at the site with locally available materials of variable characteristics. This results in a variation of strength from batch to batch and also within the batch. The factor controlling this difference for concrete of a given level of strength is called quality control. In other…
