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.
Q. How long does it take for a crew to set and pour my concrete job? A. It alldepends on the particular job specifications, weather conditions, as well as set and pour schedules. 1 â 10 yards of concrete can be poured in the same day. 10 â 20 yards usually takes about two days.our new concrete requires 2 hours of curing before it can handle light rain and 24 hours before it can withstand ANY foot traffic. Try not to bump or hit your new concrete with hard objects for the first 28 days. You will notice the color changing during the curing process.
