Abstract

This work aims to investigate the physical and mechanical characteristics of high-strength lightweight concrete components on the basis of local porous fillers and complex additives. It is theoretically substantiated and practically proven that with optimal amounts of the complex additives – micro silica and superplasticizer Melflux 5581F, it is possible to obtain concrete with a compressive strength of up to 62 MPa  and bending strength of 10.5 MPa, profitably using the microsilica pozzolanic activity and super plasticizer, which favorably changes the nature of porosity. Depending on the water/cement ratio, micro-and macro capillary pores of different origins, as well as other shape pores appear in the cement stone, which significantly affects the physical and mechanical characteristics of the concrete: strength, water absorption, water permeability, frost resistance, durability, etc.
