  • Fineness Test on Cement

    Fineness Test on Cement The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength. The fineness of grinding has increased over the years.

  • Fundamentals of Concrete

    Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the aggregate. For instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is needed to fill voids and cement the particles together than would be needed for a coarser sand.
