Properties of concrete

 &#; Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around,kilograms per cubic metre (lb/cu ft).

High Performance Concrete Topic

High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. HPC mixtures are composed of essentially the same materials as conventional concrete mixtures, but the proportions are designed, or engineered, to provide the strength and durability needed for the structural and environmental requirements of the project.

Tensile strength

 &#; Tensile strength is a measurement of the force required to pull something such as rope, wire, or a structural beam to the point where it breaks. The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example breaking. There are three typical definitions of tensile strength:

Concrete masonry unit

 &#; Composition. Concrete blocks are made from cast concrete (e.g. Portland cement and aggregate, usually sand and fine gravel, for high-density blocks).Lower density blocks may use industrial wastes, such as fly ash or bottom ash, as an aggregate. Recycled materials, such as post-consumer glass, slag cement, or recycled aggregate, are often used in the composition of the blocks.

How to Measure Foam Density | Hunker

Remember, density doesn't equal firmness, so keep this in mind when selecting a mattress. Density does reveal the quality and durability of the mattress. A denser mattress will be heavier, so it may be more difficult to move or flip around, but it should prove to be more durable because of the increased amount of compressed material.
