The density of Portland cement is 1.44 ton/m3.
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
The various types of ordinary portland cement are,Ordinary portland cement 33 gradeOrdinary portland cement 43 gradeOrdinary portland cement 53 grade
Determination of Free Lime in Clinker and Cement?
Ordinary Portland cement is form from materials of limestone or chalk and clay in proportion of 78and 22% respectively. The limestone and the clay are crushed and water is added to form slurry. The slurry is the heated at a high temperature in a klin to form clinker. The clinker is grinded into a powder and a range of gypsum is added which generate setting or hardening when water is added.
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
There are three different types of cement,Ordinary portland cementPortland pozzolana cementSpecial cements.There are 3 types of cement,OPC (Ordinary Portland cement)PPC (Portland pozzolona cement)Special Cements.There are many types of cement. These include gray ordinary Portland cement, well cement, hydraulic cement, as well as bagged cement.There are three different types of cement,Ordinary portland cementPortland pozzolana cementSpecial cements.
The specific gravity of Ordinary Portland Cement (OPC) - 43 grade typically ranges from 3.10 to 3.15. This value indicates the density of the cement relative to the density of water, providing insight into its composition and quality. Specific gravity can vary slightly based on the manufacturing process and the raw materials used.
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
Ordinary Portland cement is the most common cement used in the world, made from stucco, concrete, mortar and other materials. Slag cement is usually mixed with Portland cement and is the substance leftover after metal has been smelted from raw ore.
