Concrete technology deals with study of properties of concrete and its practical applications. In a building construction, concrete is used for the construction of foundations, columns, beams, slabs and other load bearing elements.
What is Green Concrete? Concrete which is made from concrete wastes that are eco-friendly are called as “Green concrete”. Green Concrete is a term given to a concrete that has had extra steps taken in the mix design and placement to insure ...
Non-destructive tests of concrete is a method to obtain the compressive strength and other properties of concrete from the existing structures. This test provides immediate results and actual strength and properties of concrete structure.
Quality tests on concrete are performed as a part of quality control of concrete structures. Different quality tests on concrete such as compressive strength tests, slump tests, permeability tests etc.are used to assure the quality of the concrete that is supplied for a given specification.
Segregation of concrete is the separation of cement paste and aggregates of concrete from each other during handling and placement. Segregation also occurs due to over-vibration or compaction of concrete, in which cement paste comes to the top and aggregates settles at the bottom.
Prestressed concrete is a system into which internal stresses are deliberately induced without any form of external loads to improve its performance. The internal stresses induced in the concrete structure is used to counteract the stresses coming from the external load application.
What is Lightweight Concrete? Lightweight concrete is a specialized concrete mixture made with lightweight coarse aggregates, and sometimes lightweight fine aggregates, instead of traditional aggregates.
Different types of concrete are produced based on the constituent material, mix design, the method of construction, area of application, form of hydration reaction. Details of these various types of concrete, their properties and applications are discussed.
What is Lightweight Concrete? Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit ...
Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting time of concrete for long distance ...
