ASTM C595 and AASHTO M240 were revised in 2012 to define portland-limestone cements with between 5% and 15% limestone by mass. Portland-limestone cement (PLC) has comparable performance properties to ordinary portland cement but improves the environmental performance of concrete. PLC has been used in the United …

PUG Base is a byproduct of concrete that is made in a pugmill (more on pugmills later). Unlike regular concrete, PUG Base is cement-treated road base and is a mix of sand, gravel, lime powder, and water. As such, it is of a lower grade than normal concrete. While PUG Base is strong and durable on its own, some experts choose to use a sub …
