We think the chaps at Tentacle Media have done a fantastic job with our new animation. The hazard of high pH wash water is becoming more widely recognised by the industry and we hope this short animation will help at least in some way to improve awareness and site safety for workers.
Dealing with concrete wash water correctly should be an important part of any site plan. And equally important is that the equipment you are using is properly tested.
pH is a measure of how acidic a solution is. For dilute solutions the pH scale ranges from pH 0 to pH 14, pH seven is in the middle and is therefore the neutral point; pH’s less than 7 are acidic and pH’s greater than 7 are alkaline.
The chemical reaction which causes fresh concrete to slowly stiffen and harden is quite complicated. A by-product of this process is the creation of a highly alkaline chemical that has a natural pH in excess of 12. Drinking water, by comparison, has a pH of around 6.5 to 7.
