TYPES OF COMMERCIAL CONCRETE MIXES
Commercial concrete is made by mixing water, aggregates and cement in various ratios. The materials and ratios used will add certain characteristics to the concrete. Below are some of the types of concrete available for commercial applications:
- Normal concrete: Normal concrete is a great all-around solution with enough strength for most construction work. It uses regular cement, and its aggregates include stone and sand. It has a relatively quick setting time — anywhere from 30-90 minutes.
- High-strength concrete: As the name implies, high-strength concrete can stand up to more stress. It uses less water and a higher amount of quality aggregate. Some additives can also help make it stronger. High-strength concrete can take much longer to set, but it’s suitable for high-load projects, like walkways.
- High-performance concrete: High-performance concrete is even stronger than high-strength concrete. It offers additional durability and strength for large pieces like pillars, warehouses and facades. It can stand up better to tough environments where it might be exposed to chemicals or abrasion.
- Air-entrained concrete: Lastly, air-entrained concrete incorporates small air bubbles into the concrete that can better resist freeze-thaw cycles. Normally, when water enters concrete and freezes, it increases the internal pressure and damages the concrete over time. Air-entrained concrete helps alleviate this issue for applications where freeze-thaw cycles are likely to be a problem.
