TYPES OF CONCRETE

L. Dvorkin and O.Dvorkin

Along with ordinary coarse aggregate concrete, in construction are also used

types of concrete which differ from their structural peculiarities, composition

and properties.

There are considered fine-grained concrete, high-strength concrete, concrete,

modified by polymer admixtures and fiber reinforced concrete, concrete for

special purposes – hydrotechnical, high-strength, heat-resistant, facing and

concrete for nuclear radiation protection in the given chapter.

8.1 Fine-grained concrete

Maximum coarseness of the aggregate in fine-grained concrete is 10 mm.

Sand concrete that does not contain coarse aggregate is prevalent type of the

concrete.

Y. Bagenov suggested dependence of sand concrete strength as empirical

formula:
