Grades:33 Grade, 43 Grade, 53 GradeNone (Only PPC Grade)
Constituents:Limestone, Gypsum, Clinkers, SilicaPozzolanic materials (Volcanic ash, Fly ash), OPC, Gypsum
Used for:General residential/ commercial construction worksMarine constructions, Buildings near seashores, Dams, Industrial structures, etc
(Due to its high resistance towards sulphate attacks)
Setting Time:Fast setting
(Achieves 43/53 Mpa by 28 days)
Slow setting
(Achieves 33 Mpa by 28 days)
Concrete Strength:Greater strength during the initial days of curing, due to faster setting timeInitially, the strength is not equivalent to OPC grade. However, it gains more strength than OPC with the passage of time.
