Guide: Pouring Concrete In Cold Temperatures Master Mix ...

In fact in 2017 some weather forecasts predict temperatures as low as -5°C! Freezing temperatures can have a big negative impact on freshly laid concrete, so now is as good a time as ever to read our top tips to help you correctly pour concrete in cold weather. WHAT COUNTS AS COLD TEMPERATURES? Concrete is described as being exposed to cold weather at any temperatures below 5°C, for longer ...

A Statistical Approach to Predicting Fresh State ...

Only a few studies attempted to predict fresh concrete properties like slump (Agrawal Sharma, 2010; Gomma et al., 2021; Oztas et al., 2006). This study adopted multivariate regression analysis (MRA) to model the relationships between properties (slump, air content, and density) of fresh sustainable concrete made with PLC, FA, and LWA and variables related to concrete mixture proportion. Both ...
