The hardening of concrete is a chemical reaction that requires certain conditions and temperatures. Ideally, concrete should be poured when the air temperature is between 50 and 90 degrees Fahrenheit. Cold temperatures slow the concrete-setting process, and when temperatures dip below freezing, the delay allows the water in the mix to freeze before the concrete hardens. This creates cracks in the concrete because water expands as it freezes.
Answered by The Community. Making the world better, one answer at a time. Depending on the composite of the concrete material, it can melt at different temperatures. When concrete reaches a high enough temperature such as more than 1000 degrees Celsius, it can crumble like sugar.ot everything that is solid at room temperature and normal atmospheric pressure will melt by simply raising the temperature-some things convert directly to gas (sublimate)a â¦ nd some things will decompose or react to other substances before melting (burning is one type of reaction), to answer part of the question.
