The paper presents results of research of the effect of additives-hardening accelerators on the kinetics of strength gain of composite cement with super - and hyperplasticizers. The experimental dependence the composite cement’s strength at 28 days from the percentage of the Portland cement replacement by metakaolin are given. The effectiveness of naphthaleneformaldehyde superplasticizer SP-1 in combination with the hardening accelerator NaOH for composite Portland cement are shown.
