So, what is portland-limestone cement (PLC), anyway? • PLC is a slightly modified version of portland cement that improves both the environmental footprint and the basic performance of concrete. It is now described in ASTM and AASHTO specifications, is available in Mississippi, and is used just like traditional portland cement in mix designs.
The effect of limestone granulometric composition on the properties of composite materials was studied. The studies used limestone with 3 different Blaine specific surfaces: 250 m 2 /kg, 300 m 2 /kg and 450 m 2 /kg. Tests were carried out on cement samples containing mass fractions of 10%, 15%, 25% and 35% crushed limestone, and demonstrate the importance of the granulometric composition .
