oversized aggregate placed in improperly cured concrete in freezing weather. When the January 1910 failure occurred, it showed that the dam structure and the founding bedrock had failed. The owner/operator's disregard of the engineer's recommend-ed repairs was the fatal ...
investigated in order to obtain data on intended reduction of the shrinkage deformations. The limit shrinkage values determined thereby for various concrete compositions were significantly greater, and were reached in shorter time, than can be calculated, for example, in formulas given in German ...

The Issue with Pouring Concrete in Cold Weather When temperatures dip below 40 °F, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete. If concrete curing temperatures are below freezing, the water inside the concrete can freeze and expand, resulting in crack...
Pouring concretein cold weather can be challenging since concrete needs to be protected from freezing for 24 hours to reach its minimum strength of 500 pounds per square inch. Concrete that freezes early can lose much of its overall strength. However, concrete can be successfully poured in cold...
