| Popis: | This article studies technological, physical and technical properties and corrosion resistance of cement-sand slurry. Comparative data of the strength of test samples made on mortars of equal mobility with a composition of 1:1 (C: S) using river sand with fineness moduli (Mf): 1.50; 1.35; 1.25, showed the best results in the latter case. The use of the "Mylonaft M1" plasticizer in the solution in an amount of 0.5 % of the mass of the cementing with sand with Mf = 1.25 allowed to keep the mobility of 200 mm at W/C ratio = 0.6 without loss of the mixture homogeneity. Investigation of the corrosion resistance of sample mortars with the introduction of 1 % Na2SO4 into it during the process of its preparation made it possible to achieve stability in aggressive sulfate media at low (T = 20 °C) and normal temperatures (T = 5 ° C). In order to mechanize the work on strengthening the loess soils with cementing slurry the traditional equipment used in the production (stationary solution station with a compressor and a pump) has been compared with the advanced mobile unit UNB-125 × 50 SO on the basis of KamAZ 363501. |
