WhatsApp: +86 182217550731. Fineness test 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, fig. below. Different cements are ground to different fineness.
