what is the best method to use when sealing an aggregate concrete driveway
Admixtures can be used to increase slump without increasing the water in the concrete. The type of aggregate, the air content, the admixtures, temperature and the proportions of all the ingredients affect slump. The typical slump used for a driveway is five inches plus or minus one. A pound per square inch (psi) is the unit of measurement used to describe the compressive strength of concrete.
