Dry mixture for manufacturing cellular fibro concrete and method therefor
and AlO4. The raw mixture is further subjected to -intermingling and grinding in a conventional thin-powder
grinder / mechanical activator, -bringing the mixture to a
construction site, and -adding water to the mixture, thereby obtaining cellular fibro concrete. The method allows:
-obtaining uniform mixtures, accelerating the hardening
phase, -reducing costs due to avoiding the use of autoclave, steaming, and thermal curing equipment, -deploying inexpensive equipment for mixing concrete.

A dry raw mixture for manufacturing cellular fibro-concrete comprises components preferably in the
following ratio: Portland cement 20-75%, mineralogical
additives 70-20%, microsilica 2-10%’, super-plastifier
0.6-3%, polypropylene fiber 0.08-0.15%, pore former
0.002-0.65%, and modifying ceolite additive 2- 10 %. The
mineralogical additives can be represented by: fly ashes
from coal combustion, ashes and slag, silica sand, limestone, and any combination thereof. The pore former can
be represented by aluminum powder. The structure of
modifying ceolite additive includes tetrahedrons SiO2
