The compositions of class B15-20 peplotuf concrete on tuff ash and crushed stone with the use of a plasticizer for use as a structural and thermal insulation layer in two-layer wall panels are proposed. The calculated heat transfer resistance of a two-layer structure is determined, and the dependence of the density and strength of the mixture on the cement consumption per 1m3 is established.

Keywords: tuff rubble, tuff ash, expanded clay concrete, peplotufobetonnaya mix, multi-layer wall panel, structural and thermal insulation concrete
