AbstractAbout AuthorsReferences
The prescription and technological parameters for manufacturing polymer cement compositions based on portland cement and aqueous epoxy emulsion cured by aliphatic polyamine were developed. The concentration dependence of the technological and physico-chemical properties of the material was studied. The optimum polymer-cement ratio is established (P/C=0,5). The degree of curing of epoxy resin in the composition of the compositions was studied at different stages of their hardening. With the aid of electron microscopy with elemental analysis there was investigated the structure of polymer-cement compositions at P/C=0,5, in which the dispersion medium is an epoxy polymer, and the disperse phase – a cement stone. The strength of this polymer-cement composition is 2.75 times higher than the strength of a “pure” hardened cement paste
