Concrete joints are normally used to prevent cracks when the concrete shrinks by creating forming, tooling, sawing, and placing joint formers. The pre-planned cracks will provide a better finish concrete product and will be formed in specific locations where those cracks could be monitored.

The water-cement ratio is the weight of the mixing water divided by the weight of the cement. High-quality concrete is produced by lowering the water-cement ratio as much as possible without sacing the workability of fresh concrete, allowing it to be properly placed, consolidated, and cured.

Quickly calculate concrete slab and footing pours by entering the depth, width and length to find the number of cubic yards or bags of concrete needed for your project. Give these calculations to your ready-mix supplier or use them to estimate how many 40, 60 or 80 lb. bags of concrete to buy.
