Lightweight Structural Concrete with an Increased Coefficient of Structural Quality
Abstract: Compositions of lightweight aggregate concrete with an increased coefficient of constructive quality, characterized by compressive strength at the age of 28 days of normal hardening of 46,1…65,3 MPa (KKK 25,2…33,1) and ensuring the production of concrete mixes with a workability index of at least P2 are developed. The influence of a combination of fine aggregate of expanded clay and granite sand, silicafume, air entrainment on the slump of the concrete mix, average density and the compressive strength of concrete is investigated.
Keywords: lightweight structural concrete, coefficient of constructive quality, workability, silica fume, air entraining additive.
