When Is it Too Cold to Pour

Mar 31, In seasons where temperatures are liable to fall below 40 degrees Fahrenheit (4.4 degrees Celsius) or exceed 90 degrees Fahrenheit (32 degrees Celsius), the ratio of water, cement and aggregate can shift, changing the end result. In high temperatures, water can evaporate and result in a misshapen and weaker final product, but in low temperatures, the freezing of water in the concrete mixture


To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment. Mixing Tools. Sikafloor-161 must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable
