Composition of a Dry Mix for Non-Autoclaved Foam Concrete of Natural Hardening

A dry mix composition for manufacturing the non-autoclaved foam concrete of natural hardening on the basis of Portland cement, foaming agent Ufapore, quickening and plasticizing agent Tsitrat-T, microsilica MK-85, sulfate-aluminate additive PCAM, basalt fiber, and polymeric powder Vinappas-8034 has been developed. In the course of mixing the dry mix with water at B/T 0,4–0,6, subsequent mechanical swelling (2000 rpm), and foam mass hardening, the non-autoclaved concrete of 400–800 kg/m³ density (depending on B/T), 1,1–3,4 MPa strength, low water absorption (50–60%) and without shrinkage cracks is formed. Its mechanical properties are very close to autoclaved concrete properties.
