The invention relates to the field of construction materials and can be used for producing naturally hardening non-autoclaved cellular fibre-reinforced concrete. The non-autoclaved cellular fibre-reinforced concrete is produced from a raw mixture comprising, in percent: Portland cement: 5.2-75.198%, mineral filler 20-70%, microsilica 2-10%, superplasticizer 0.6-3%, modified zeolite admixture 2-10%, polypropylen fibre 0.10-0.15%, composite pore-forming agent 0.002-0.65%, hydrophobizing agent 0.1-1%. The superplasticizer and the hydrophobizing agent are calculated from the cement mass. The above mixture is subjected to a stage of preliminary mixing and is ground and activated in mechanical activators, subsequently it is bagged into 25 kg bags, into a big bag type package, and onto cement carriers. The technical result is an increase in strength, frost resistance, and an acceleration of the hardening of the cellular fibre-reinforced concrete at reduced specific weight, a reduction of shrinkage, energy saving, the possibility of use at construction sites according to the principle of "simply dilute with water". |
