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:
