What is Concrete? Composition & Types of Concrete
Concrete Definition: Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate ( sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.
Main Properties of Concrete for Construction
Concrete is a mixture of several materials. At the hardened state, this heterogeneous material becomes stone-like mass. The extensive use of concrete in the construction field has made it a material of huge concern for engineers. To participate in the vast uses of concrete an engineer must know its properties.

Permeable Concrete: Composition, Properties and Application
Permeable concrete, also called pervious concrete, is a special concrete type prepared to allow water to deliberately infiltrate through it and get drained. The purpose of doing this can be twofold. Firstly, it helps reduce the runoff from a site and secondly, it can effectively serve as a method of ground water recharge.
What is Mass Concrete?
Mass concrete is defined as heavy volume concrete work with large dimensions and boundary conditions that are prone to elevated temperatures due to a higher rate of the heat of hydration. The high temperature in concrete results in high thermal stresses, cracking, and reduced long-term strength gain. Hence, the main factor distinguishing mass ...
Definition, Method, Advantages, Disadvantages
Concrete can withstand a great amount of compressive stress but it has a very low tensile strength. Because of low tensile strength, concrete gets cracks when subjected to maximum load.. As the name indicates prestressed concrete is a form of concrete in which internal stresses are introduced before its application so that it can counteract the tensile …
What is Cellular Concrete? Types and Materials
Cellular concrete is a special engineered concrete manufactured by mixing Portland cement, sand, fly ash, water and pre-formed in varied proportions to form a hardened material having an oven-dry density of 50 pounds per cubic foot (PCF) or less. As per the definition by ACI, the density of the cellular concrete must be lesser than 50 ...
