FIELD: chemistry.
SUBSTANCE: light fibre-reinforced concrete is prepared from a mixture containing, vol. %: portland cement 10.0 - 22.0, granular foamed glass with particle size of 0.1 - 5 mm 40.0 - 70.0, packed or unpacked microsilica 0.5 - 3.0, generation 4 superplasticiser 0.1 - 0.3% of the weight of the binder, fibre 0.5 - 4.0 g per litre of the ready mixture, water - the balance. The light fibre-reinforced concrete is prepared from a mixture which further contains secondary filler - microcalcite with particle size of 5-100 mcm or dolomite powder or sieved sea sand. The light fibre-reinforced concrete is prepared from a mixture wherein the generation 4 superplasticiser used is polycarboxylate ether Sika Viscocrete 105P.
EFFECT: obtaining articles with a smooth front surface and low heat conductivity.
