Description
Summary:The construction industry widely uses concrete for various purposes. The addition of lightweight fillers to the compounding of concrete allows to obtain lightweight concrete with high heat-insulating indicators and a smaller mass. Various materials can be used as fillers, including industrial waste. The paper is devoted to the study of the properties of lightweight concrete with the addition of sawdust. As a result of experimental studies, the strength properties of sawdust concrete produced without the use of mineral fillers (sand) were determined. The positive effect of tempering the mixture with latex emulsion on the strength properties of sawdust concrete has been established. The strength characteristics of samples made with the addition of a latex emulsion were 3.65 MPa at a density of 1080 kg/m3. Such indicators allow using the material as a structural thermal insulation during construction.
