Conclusions
- 1.
Rollcrete has creep, the general regularity of the development of which in time and as a function of the age of the concrete can be described by the formula proposed earlier by Aleksandrovskii and widely used for ordinary concrete.
- 2.
As for the quantitative side of the problem, the presently available scanty data on creep of rollcrete indicate that its creep is higher than creep of ordinary concrete.
- 3.
Formula (1) can be recommended for calculating the stress and thermal stress states of rollcrete masonry with consideration of creep; for engineering calculations, stress relaxation coefficients were obtained and are represented for rollcrete of class V10 by a family of curves convenient from the viewpoint of practical use.
