Once the concrete has been poured it’s important that it undergoes proper curing and hardens correctly.
The first days are crucial. It is especially important to protect concrete from rain- or snowfall as well as evaporation. Protection of concrete will reduce the risk of cracking. There are various standards that must be met to achieve the best results – and we know how.
We offer knowledge about concrete. Knowledge that makes things easier for you in your project. We are The Concrete Specialists.
Cold Weather Concreting
Cold weather is defined as a period when the average daily temperature falls below 40⁰F for more than three successive days. Special considerations are required when batching, placing, finishing, curing, and protecting concrete against the effects of cold weather.
Hot weather is defined as any combination of high ambient temperature, high concrete temperature, low relative humidity, wind speed, or solar radiation that tends to impair the quality of the freshly mixed or hardened concrete.
Evaporation Retarder as a Solution to Plastic Cracking
Plastic cracks form within hours of placement, during the finishing and curing process though they may not be visible until the next day or week. Cracks generally run parallel to each other, spaced 1 to 3 feet apart, are typically relatively shallow, may appear random in pattern, and do not intersect the perimeter of the slab. Plastic cracks are unsightly but rarely impair the strength or durability of the concrete.
