Abstract

Due to the creation in Ukraine of the industry, the production of light concrete for the construction of residential porouse building aggregates became a desirable development.

The use of light concrete leads to a significant reduction in labor costs, estimated cost of construction, specific capital investments, transport costs, the amount of cement, reinforcing steel, reducing the mass of buildings.

Obtaining lightweight concrete with high performance properties on the basis of corrosion-resistant substrates and light fillers from industrial waste is an urgent task.

The aim of the study is to obtain, on the basis of light fillers – sulyroactsporytoconcrete, obtained from waste from mining and processing plants and activated clay, light bionites with high operational characteristics.

The analysis of the results of the selection of light batons` warehouses showed that their strength on porous fillers – sulyroactsporytoconcrete, from raw materials increases with increasing time of mixing and the cost of binder in concrete.

As a result of these experiments, the composition of light concrete on porous fillers – sulyroactsporytoconcrete, with costs of cementite less standard for 50-60%.

Constructed dependencies on the strength of light concrete on porous aggregates – sulyroactsporytoconcrete from technogenic raw material to tensile bending from compressive strength.

The shrinking process goes intensively for the first 100 days, which is explained by the drying of the samples and less than these values for lightweight concrete on expanded clay aggregate by 15-20%.

The research allowed us to prove that the increase in strength and reduced performance of lightweight concrete based on sulyroactsporytoconcrete from waste mining and processing plants and activated clay is achieved by increasing the strength of contact « sulyroactsporytoconcrete – cement stone», limited by the affinity of the warehouses of the binder hydration products and sulyroactsporytoconcrete.
