— Microsilica in concrete contributes to strength and durability two ways: as a pozzolan, microsilica provides a more uniform distribution and a greater volume of hydration products; as a filler, microsilica decreases the average size of pores in the cement paste.

Microsilica in concrete improves its strength and durability as it provides more uniform distribution and a greater volume of hydration products, and decreases the average size of pores in the cement paste.

 — The first one is the pre-induction period (duration time: a few minutes, just after being exposed to water) where the rapid hydration of C 3 S occurs. When C 3 S is exposed to water, at the surface level, ions start to a rapidly dissolve, with release of hydroxyl and silicate ions in the liquid phase.

Agreement signed between Oman Cement Company and Sohar Aluminum for the utilization of SPL, that is generated from Aluminum process, in cement manufacturing. The SPL (spent Pot-lining) is a brick that is rich in calcium and silica which have an ended life.

 — Nano-silica (nS) or silica nanoparticles, also known as silicon dioxide nanoparticles, can be used as additives for improving concrete's mechanical and durability properties [24], [25], [26]. The effect of nS on nanostructure of cement paste also confirmed the improvement in concrete durability [27].

The total current production capacity of Oman Cement Company is 2.4 million MTs Cement. Oman Cement has a range of top quality products to meet your requirements. We have given a list of our products below with detailed description and specification data.

 — Silica is obtained from a nearby quartz phyllite source, around 3km away. Iron ore is sourced from the same area. Our alumina source is kaolin from around 600km away. We used to import bauxite from India for our alumina but since we switched to Omani kaolin we proudly produce cement that has Omani raw materials.

Silica: Silicon dioxide is known as silica, chemical formula SiO 2. A sufficient quantity of silica should be present in cement to dicalcium and tricalcium silicate. Silica imparts strength to cement.

 — Silica fume concrete for the rehabilitation of damaged bridge and marine columns and piles for use in mine tunnel linings and rock stabilisation. Silica fume-infused high-performance concrete (HPC) for marine buildings, parking, high way bridges, and bridge deck overlays.
