LP cements can provide very effective alternative to
Portland cement, mainly for secondary applications such
as masonry mortar, plastering, base/sub-base for flooring,
etc. A typical LP cement will consists of 30% lime, 60%
pozzolana and 10% calcined gypsum, all three being interground
in a ball-mill. Such cement will have an energy
content of 2.33 MJ/kg.
