Reinforced concrete

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete''s relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is ...

properties of concrete : définition de properties of …

Concrete tests can measure the "plastic" (unhydrated) properties of concrete prior to, and during placement. As these properties affect the hardened compressive strength and durability of concrete (resistance to freeze-thaw), the properties of workability (slump/flow), temperature, density and age are monitored to ensure the production and placement of ''quality'' concrete.

Lightweight concrete

Good thermal insulation properties make foamed concrete also suitable for sub-screeds, filling under-floor voids and insulation on flat concrete roofs. Lightweight structural concrete Lightweight aggregate concretes can be used for structural applications, with strengths equivalent to normal weight concrete.

Properties of Concrete Blocks — Strength

Properties of Concrete Blocks — Strength. In the use of concrete blocks for the walls of buildings, the stress to which they are subjected is almost entirely one of compression. In compressive strength well-made concrete does not differ greatly from ordinary building stone. It is difficult to find reliable records of tests of sand and gravel ...

The Effect of Aggregate Properties on Concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
