This works aims to study the effect of silica fume on the properties of alumina cement and sulphate resisting cement composite up to 90 days. The substitution of alumina cement by silica fume tends to increase the water of consistency and elongate the setting time. The apparent porosity increases and the compressive strength decreases with silica fume content. Melamine formaldehyde sulphonate (MFS) was used as super-plasticizer to decrease the mixing water, which affects the properties of the cement paste.
