New Composite Mineral-Polymers and Thermoplast-Concrete for Using in Road and Special Construction

Results of the study of physical-technical properties of mineral-polymers and thermoplast-concrete under development, as well as the data on changes in the strength properties of these concretes depending on the content of the polymer component in their compositions, are presented. In the course of the analysis of results it is established that the increase in the content of polymer binder in composite composition is accompanied by the decrease in compressive strength and by increase in bending resistance. Along with this, there is an increase in the concrete elasticity which as the ratio of R_bending/R_compression has the following values for concretes with the compressive strength of 75–85 MPa – 0.20–0.23 and for concretes with the compressive strength of 45–55 MPa – 0.40–0.50. It is also established that elastic mineral-polymer-concretes with their closed porosity in comparison with cement concretes have smaller values of water absorption, smaller decrease in the strength in the course of humidification and significantly higher frost-resistance.
