The results of investigation show that the properties of liquid disperse medium of structural system influence slightly the dilatancy of cement slurries. Plasticising admixtures with a different chemical composition slightly increases but air‐entraining and viscosity‐modifying admixtures slightly reduces the...
Effects of aggressive media on the properties of the CBM It is well known that aggressive media can cause the degradation of the physico-mechanical properties, chemical and composition phase and pore structure of the attacked CBM. This fact enables the possibility of studying the progress of the ...
PURPOSE: To obtain a cement admixture and a cement composition in which strength is well provided, and which is effective in producing quick hardening cement excellent in alkali aggregate reaction resistance and is mainly used for the civil engineering and construction industry. ;CONSTITUTION: A cemen...
PURPOSE:To form a high-strength polymer composition having excellent characteristics using a cement blending material by forming the cement admixture using a polymer containing a mixture of a specific synthetic resin emulsion and synthetic rubber latex prepared by using a dispersant and surfactant as emu...
