In general, Concrete can be placed safely without damage from freezing throughout the winter months in cold climates if certain precautions are taken. Cold weather is defined as a period when for more than 3 successive days the average daily air temperature drops below 5°C (40°F) and ...
Same goes for concrete work in general, but especially when cold weather comes on unexpectedly. To handle the cold, have everything you might need on hand and review these tips:Frozen ground—NEVER place concrete on frozen ground or onto ice or snow. There are a couple of problems with ...
How cold is too cold to pour concrete? And what should you do if it’s swelteringly hot, but you need to make a concrete repair? While you can pour concrete in cold and hot weather, it’s necessary to take certain precautions to ensure the concrete sets properly. Your pavement repairs...
Handling bleed water: Wait until all bleed water has evaporated before finishing. Concrete poured and placed in cold weather has a much slower setting and curing time, so bleeding will start later than expected. Be prepared to handle more bleed water than is typical in regular concrete placement...
Objective: The study focused on the application of urea to the cold weather concreting. One of the advantages of this method is to simplify curing after concrete placement at low temperatures; only an anti-evaporation sheet is necessary to keep fresh concrete wet until finishing of concrete curing...
In hot regions, cold water or ice is used to lower concrete mixture temperatures. Consequently, the hydration rate is reduced, and the slump-life is extended [13]. On the contrary, heating concrete ingredients is recommended in cold weather concreting [14]. Show abstract The behavior of self...
You’ll also want monitoring equipment to make sure you stick to your desired cold weather concreting specification. Depending on what it is, you may have to prevent the concrete temperature from going below a specified value during placement and curing. You may also need to keep the differentia...
