In a general definition, hydraulic cement is a powder, that when mixed with water, undergoes a chemical reaction called hydration. The cement paste hardens and gains strength as it cures over time. Portland cement is the most common type of hydraulic cement and forms the basis of most cementitious materials used for concrete, mortar, and grout.

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.

Measuring and controlling the particle size distribution of cement is important both in order to achieve the desired product performance and to control manufacturing costs. Laser diffraction is the more popular method to determine the particle size distribution as the technique is quick, easy, reproducible, and provides a complete picture of the full size distribution.
