Every construction worker prefers working outdoors when the weather is perfect – 60 degrees and dry. In fact, fresh concrete needs those perfect weather conditions. Unfortunately in the Mid-west you may only get a dozen days a year with those particular working conditions. When winter rolls in many business wonder how to meet their construction goals.
Difficulties with pouring fresh concrete outdoors
- Wet, muddy, frozen or snowy site conditions make it difficult for people and equipment to move around a construction site.
- Rain is bad for fresh concrete. Rain can ruin the screed finish and prevent the face of the concrete from getting hard, causing low durability.
- Wind and sun are bad for fresh c oncrete. Wind and sun can cause accelerated drying of the concrete surface which can lead to drying shrinkage, cracking, and low durability of the concrete surface because the water evaporates before the cement can use the water for curing.
- Cold is bad for fresh concrete. Curing concrete is based on time and temperature. Higher temperatures equal faster curing. Fresh concrete will not cure in freezing conditions.
Benefits of pouring concrete indoors
- A temperature controlled indoor environment gives us “t-shirt weather” year-round for pouring concrete.
- Heated rock, sand and water for mixing fresh concrete; no matter how cold it gets outside our fresh concrete is toasty warm.
- Accelerated curing using form heaters. During curing, the form heaters raise the temperature of the concrete to between 90 and 140 degrees to ensure high early strength.
- No wind, rain, sun, cold or snow to interrupt pouring fresh concrete.
Fortunately cured concrete is resilient to all types of weather conditions. Wells Concrete manage these changing weather conditions by pouring concrete indoors. All four Wells production facilities pour concrete indoors, allowing the concrete to remain unaffected by the changing weather and seasons. The perfect construction site is actually indoors.
