The aim of the invention is to increase the mobility of the concrete mixture while maintaining the strength of the concrete, as well as the disposal of production waste. The main product includes, in May.%: Portland cement is the basis, amino acid production is a waste - the biomass of the producer of L-leucine is 0.05-2.0. 3 tab.

Description

1 13

The invention relates to the production technology of building materials, to the preparation of a porting cement based on cement and additives. The resin is intended for the manufacture of concrete mix.

The purpose of the invention is to increase the mobility of the concrete mixture while maintaining the strength of the concrete, as well as the utilization of production waste.

Used to portland cement, the additive is an amino acid waste product - biomass residue.

sy producer L-leucine and includes, wt.%:

Waste production of amino acids is obtained from the culture fluid by coagulating the cells of the producer of L-leucine under the action of calcium salts.

A coagulum is a suspension of lime and. phosphoric acid.

Biomass has a moisture content of 40-80%

The additive is a fine powder which is intended to be introduced into the mixing water that is in the gutter with it.

The preparation of the concrete mixture was carried out according to conventional technology. Heat treatment of concrete was carried out according to the mode 2 + 3 + 6 + 3 at an isothermal process temperature of 80 ° C. The cement-to-concrete ratio of the concrete mixture with the introduction of various amounts of additives was constant.

Table 1 presents the results of experiments showing the effect of the waste of the production of amino acids — the biomass of the producer of leucine, on the mobility of cement-concrete mixtures at the flow rate

cement 270 kg / m and a W / C equal to 0.68,

Table 2 shows the effect of the additive on the strength of concrete.

The concrete mixture obtained by the prototype provides an increase in plasticity from 1 cm (for the control sample) to 8 cm using the OK method, and the strength of the concrete increases after steaming from 24.1 to 27.0 MPa, i.e. persists.
