- Abstract
Background. It is known that the production of cement is energy and material-consuming, and with these features, the actual problem of the construction industry is to increase its strength. Purpose. Increasing the strength of cement while reducing the consumption of clinker for cement production. Methodology. Determination of cement strength was carried out according to GOST 197-(1, 2, 3)-2020, compression test - on the press "ATOM TEKNIK 20 t", elemental, IR spectroscopic, thermogravimetric control of its samples was performed. Originality. It is shown that the introduction of microsilica and polycarboxylate plasticizer into the composition of cement contributes to an increase in the strength of cement up to 21%. The mode of activation of microsilica in triethanolamine at a temperature of 60°C was chosen. Findings. Activated silica fume accelerates the secondary hydration of Ca(OH)2, the plasticizer improves the dispersion of cement particles, the compressive strength of the product during its hardening is determined, IR spectra, SEM, RXD, TGA samples are presented.
