Thermal stresses of concrete in a large block
Conclusions 1. The results of the investigations confirm the crack resistance of blocks with planar dimensions of 80×30 m when placing concrete in layers 0.75 m thick both in the summer and winter with surface and pipe cooling of the concrete. 2. The maximum tensile stresses (16 kgf/cm2) occurred in the middle part of the block in layers of the spring masonry during their secondary cooling. The maximum tensile stresses did not exceed the tensile strength of the concrete. 3. The thermal state of concrete in large blocks in layers 0.75 m thick meets the requirements of the technological regulations of concrete placement by the Toktogul method.
