Concrete pH Testing problems and Solutions Stovers

Concrete pH Testing problems and Solutions Once pH testing is done and you have high readings there seems to be a lot of different opinions on what needs to be done The pH of new concrete will be approximately 12 to 13 mostly due to calcium hydroxide which is a normally byproduct of cement hydration As a concrete surface reacts with carbon dioxide in air the pH of the surface gradually is
