Tests of the physical and mechanical properties of prototypes of Portland cement from a three-component raw mixture, carried out in accordance with the requirements of GOST, showed that with a saturation coefficient of KH=0.88-0.89 and a silicate module n=2.5-2.7, the prototypes show strength characteristics at 28-day hardening under normal conditions for bending within 6.2- 6.6 MPa, and for compression within 41.0-42.2 MPa. At the same time, it should be noted that hydrothermal treatment at a temperature of 95 ± 5°C also leads to a set of strength within 50-60% of the grade strength (Table 4.). Download 0.63 Mb.
