How to stop concrete dusting - Causes, Effects, and Repairment

It produces a very high water-cement ratio and the outcome will be a low strength surface layer. Inadequate curing. If proper curing is done and allowed concrete surface for drying rapidly mainly in hot, dry, and windy season, then it will result in the weaker surface layer. They may contain dust even under foot traffic. Inadequate compaction. Reduction on abrasion resistance is the

Hot Weather Concreting | Problems, Effects and Precautions

 · Cement temperature has only a minor effect on the temperature of freshly mixed concrete because it represents a relatively small percentage of the total mixture. Concrete Curing is a hydration process and requires water to be present. Forms should be sprayed with water to keep them damp, or they will absorb part of the mixing water. As soon as the concrete has set
