SU698951A1 - Raw mixture for producing silicate concrete - Google Patents

Description

The invention relates to the preparation of building compositions used in particular in the construction of mines.

Raw materials for the manufacture of silicate concrete are known, including liquid glass, ground granulated slag, aggregate, and fine ground quartz sand.

The disadvantage of this mixture is that Bsp: is better than a mixture when using aluminum .-- n-; : Eve powder occurs as a result of intensive hydrogen evolution. Therefore, in mine construction, when, under safety conditions, the percentage increase in hydrogen content in air is unacceptable, it is impossible to use such a mixture.

In addition, the well-known raw mix for the manufacture of silicate (gx) concrete, including Portland cement 8-10, liquid glass 52.5-79.5, shlomk lomnny 837 and perhydrol 2.5, is such a mixture of yabl with rc most flat). to the invention

Its disadvantage is the low strength and high coefficient (}) of thermal conductivity. The purpose of the invention is to increase the strength and reduce the coefficient of thermal conductivity.

This is achieved by the fact that the raw mix for the manufacture of silicate concrete, including Portland cement, water glass, blast furnace slag and intumescent, contains hydroponite as intubate in the following ratio of components, weight h; Portlandzek-1ent5-15

An example of the preparation of the mixture. Dry components - portlag cement, blast-furnace and dispersed hydroperite are poured in an arbitrary sequence into the mixer, where mixing is carried out. Then, in the same smollen immobility they pour in liquid STR and LRG.

The second mixing is carried out until the continuity of the process of preparing a homogeneous mass is obtained. The mixture is mixed, the separation of the process of introducing liquid glass of the process into two stages is permissible. In the first stage

it reacts with. hydroperit, it is carried out the preparation of dry, uniformly distributed throughout the whole volume, then the mixture obtained

As a result, the pro-packer begins in an airtight container for the process of gas release, causing the mixture to swell. Intensive gas evolution begins in minutes. After a match, it allows, depending on 0.

In the second stage, as necessary, mix the mixture of dry ingredients with liquid glass.
