Moreover, addition of bioactive mineral filler (BCP) improves significantly mechanical properties of these materials. The compressive strength and compressive modulus values increased with increasing MAAH/MMA ratio. The paper considers variants of lightweight cement compositions with additives of various substances, such as clay components, ash systems, silica additives.

hardening of the cement composition containing the polyester microfiber the cement hydration products. The setting time was affected strongly by the concentration of double bonds and was rapidly shortened with its increase. Compositions Through the Microfiber Addition. The maximum temperature during cross-linking was found to decrease with increasing MAAH content. The standard thickness of mortar in brickwork is 1mm or 1cm. The latter was characterized by determination of the weight loss and observation of changes in samples morphology by SEM. If too much mortar is placed on the bricks it can cause cracking. The Bogue model is derived by dening the chemical composition of cement compounds as C3S for alite, C2S for belite, C3A for aluminate, and C4AF for ferrite 18. The aim of this study was to examine the influence of MAAH/MMA ratio and incorporation of biphasic calcium phosphate (BCP) filler on the maximum curing temperature, setting time, compressive strength and modulus of the cured materials, as well as on their hydrolytic degradation. composition of cement compounds as the main reason for the difference between the Bogue model and the experimental values 8,1517.

The clinker must be combined to a low residual free lime. New biodegradable poly(3-allyloxy-1,2-propylene)succinate-based materials were obtained by cross-linking poly(3-allyloxy-1,2-propylene)succinate (PSAGE) with methyl methacrylate (MMA) and methacrylic anhydride (MAAH). Durability of concrete made from cement is certainly determined by the clinker quality and composition.
