Test samples,Effects of cement fineness on cement properties,Effects of cement fineness on cement properties. Q. How does the fineness to which the clinker is ground affect the properties of the cement? A. Increasing the fineness increases the rate of hydration of cement, which increases the rate of gain in strength and also the rate at which heat is liberated as in Type III compared with Type I cement (ASTM C150).Effects of colloidal nanoBoehmite and nanoSiO2 on,The influences of colloidal nanoBoehmite (CNB) and colloidal nanoSiO 2 (CNS) on fly ash cement mortar hydration and microstructure development of fly ash cement pastes were investigated.
