SU1227610A1 - Fibrous concrete mix - Google Patents

Description

The invention relates to compositions of dispersion reinforced concrete concrete mixtures (fibrous concrete mixes) and can be applied in the building materials industry.

The aim of the invention is to provide compressive strength, water and frost resistance of concrete.

Example. The preparation of fnbro-fieTOHHOft mixtures is carried out with (in this way ,.

Portland cement is mixed with 1 mixing water, into which calcium chloride is directly introduced and the sulphite-yeast mash is the surfactant additive. Then basalt fiber is introduced into the mixer; oncological ground construction sand and pyrite cinder, stirring for 1 minute, after which they are filled in and mixed together for 1-2 minutes.
