Apr 12, 2020 Small Particle If we have OPC cement with small or fine particles then these particles are unattached to each other.So, when we add water into it this water reacts with these particles simultaneously as these are not attached to each other. So, in these types of cement particles, the hydration process is fast as compared to the large particles.
Portland cement - Designing Buildings - Share your construction industry knowledge. Portland cement is used to make almost all concrete. It is also the principal cement used in most masonry mortars and renders. The most commonly used type of Portland cement is Ordinary Portland Cement (OPC), but there are other varieties available, such as white Portland cement.
Conventional Portland cement-based materials are considered to be responsible for 58% of total man-made CO 2 emissions. Due to this fact, finding an alternative cementitious system, with lower CO 2 foot print than that of ordinary Portland cement (OPC), is one of the major challenges of cement and concrete industries.
(CLSM). Production of Ordinary Portland Cement (OPC) requires 60 to 70% of CaO phases and generally, it is supplied by using limestone (CaCO 3) phases. The significant amount of calcium carbonate phase present in wood ash makes it a potential material to be used as a raw material for cement production.

Advantages of ordinary portland cement OPC has great resistance to cracking and shrinkage. The initial setting of OPC is faster than that of PPC. The treatment period of OPC is shorter than PPC hence the cost of treatment is reduced, therefore recommended where the cost-prohibitive treatment will occur.
