Cold weather, in terms of concrete pours, is more than three successive days when the averagedaily air temperaturedrops below 40°F and stays below 50°F for more than one-half of any 24-hour period.1Under these cold weather conditions, special techniques need to be applied. Longer work pe...
First, it’s not only important to consider ambient temperature but also how you will keep the concrete at the correct temperature while it cures. When pouring concrete in cold weather, many people use heated enclosures or insulated blankets to prevent the concrete from freezing. Alternatively, w...
Pouring concrete in cold weather can be tricky. Get expert tips for dealing with frozen ground, worker safety and more so your concrete turns out well.
Before concrete pouring should know the weather situation in a timely manner. 在具体瓦砾最大微粒大小和转达的管子直径的比率适当为1:3,沙子比率应该在40% ~ 45%,水水泥比率之间应该在0.5 ~ 0.55之间,暴跌应该在15之间到18 cm。 在混凝土倾吐应该及时之前地知道天气情况。 [translate] ...
Hot weather can cause problems for concrete at some point, usually between 75oF and 100oF. Low relative humidity and high wind speed cause the most problems most of the time. The harsh sun and high temperature, along with these conditions, make it very likely that problems will happen. Ther...
In cold weather, the temperature of the concrete can be controlled by providing appropriate curing conditions to maintain insulation and strength gain, such as the use of heating systems. High curing temperatures can also be controlled when mass pouring with cooling pipes. ...

The article discusses WeatherAPP, a smartphone application from Holcim that provides a four-day forecast for temperature, wind speed, and humidity, useful information to those pouring concrete. WeatherAPP can help prevent plastic-shrinkage cracking by calculating the likelihood of that happening under ...
In neighbouring Yunnan Province, six people were killed and 35 injured in rain-related disasters, including the partial collapse of a steel and concrete bridge over the Yuan River in Yuxi county, about 60 miles south of the provincial capital of Kunrning. Earlier, at least 29 others were ...
Weather stationsare usually equipped to measure atmospheric conditions for weather forecasts and studies on the weather and climate. Ananemometeris a device often found in such stations that measures wind speed and direction. The anemometer shown in the comic is a typical three-cup anemometer, whose...
