In the long term, the only way to achieve CO2 neutrality in dry mortar is to use low-clinker cements and cement substitutes. The reduced early strength of the building products used must be compensated for in order to continue to have floors or walls that can be used quickly and possibly at an early stage. With SikaRapid®-820 P, Sika offers a highly effective, powdered hardening accelerator for cementitious dry-mix mortar systems. With low-clinker formulations, the early strength can be increased enormously even at low temperatures.
