32.5, 32.5R , 42.5N and 42.5R

OPC 42.5 N
OPC 42.5N is ordinary Portland cement with standard strength development. The most popularly used cement on the market today, OPC 42.5 comes in two sub grades. There is OPC 42.5 R, which attains strength quickly, and OPC 42.5 N, which attains it at the normal rate. With the exception of applications which require high strength

OPC 42.5 R
OPC 42.5 R Ordinary Portland cement 42.5 is the standard grade of cement used in the majority of ordinary cement applications, such as pavements, residential buildings, and pipes. OPC 42.5 comes in two sub grades, OPC 42.5 R, and OPC 42.5 N. OPC 42. 5 R develops high strength early in the curing phase, whereas

OPC 42.5
OPC 42.5 OPC 42.5 is a general use grade of ordinary Portland cement. Replacing the once popular OPC 33 in general cement work whilst maintaining its duties as a medium strength cement, OPC 42.5 is commonly used for both construction and pre-cast work. OPC 42.5 can therefore be found in a multitude of locations, from
