INFLUENCE OF TEMPERATURES AND SIZES OF WORK SEQUENCE ON CRACKS FORMATION IN RC WALLS

: The construction of the underground watertight structure is not only conditioned by the watertightness of the foundation slab, but also by the walls. The formation of a crack and thus the amount of reinforcement required to control the occurrence of a crack are dependent on several factors. The amount of tensile stresses occuring in the wall is mainly influenced by the ambient temperature at the time of concreting, the temperature of the foundation slab, which is already hardened, and the ratio of the height of the work sequence of the wall to its length.
