workability of concrete
1Concrete — This article is about the construction material. For other uses, see Concrete (disambiguation). Outer view of the Roman Pantheon, still the largest unreinforced solid concrete dome.[1] …
2Concrete slump test — A tester performing a concrete slump test. The concrete slump test is used for the measurement of a property of fresh concrete. The test is an emprical test that measures the workability of fresh concrete. More specifically, it measures the… …
3Properties of concrete — Concrete has relatively high compressive strength, but significantly lower tensile strength, and as such is usually reinforced with materials that are strong in tension (often steel). The elasticity of concrete is relatively constant at low… …
4Types of concrete — There are many types of concrete, variations of installation, composition, finish and performance characteristics. A highway paved with concrete …
5Fiber reinforced concrete — (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and… …
6Aerated autoclaved concrete — Autoclaved Aerated concrete (AAC), or otherwise known as Autoclave Cellular Concrete (ACC), is a lightweight, precast building material. AAC provides structure, insulation, fire and mold resistance in a single material. AAC products include… …
7Colloid — Milk is an emulsified colloid of liquid butterfat globules dispersed within a water based solution. A colloid is a substance microscopically dispersed evenly throughout another substance.[1] A colloidal system consists of two separate phases: a… …
8Plasticizer — Plasticizers are additives that increase the plasticity or fluidity of the material to which they are added, these include plastics, cement, concrete, wallboard and clay bodies. Although the same compounds are often used for both plastics and… …
9Air entrainment — is the intentional creation of tiny air bubbles in concrete. The bubbles are introduced into the concrete by the addition to the mix of an air entraining agent, a surfactant (surface active substance, a type of chemical that includes detergents) …
10Foam Index — Test is a rapid method to determine the relative levels of Air Entraining Agent (AEA) needed during concrete mixing, with or without mineral additives like combustion fly ash, that control air void volumes within cured concrete. [… …
