Special Types of Concrete

Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known ...

Jun 22, 2020· Shrinkage compensating concrete (Type K), with an experienced contractor and designer, can allow a reduction or elimination of joints. Reinforcement (rebar or steel fibers) is placed and the concrete actually expands as it cures, resulting in tensioning of the steel. Eventually, the concrete shrinks back and behaves similar to a post-tensioned ...

SPECIAL CONCRETE

In general, if fresh concrete is poured over a hardened concrete surface, there is a chance of failure of fresh concrete surface due to weak bond with old surface. To make the bond stronger, bonding admixtures are added to cement or mortar grout which is applied on the concrete surface just before placing fresh concrete.

Special mixing, placing, and curing practices may be needed to produce and handle high-performance concrete. Performance tests are usually required to demonstrate compliance with specific project needs. High-performance concrete has been primarily used in bridges, and tall buildings for its durability, strength, and high modulus of elasticity.
