Alkali Silica Reaction

ASR is a reaction between the alkali hydroxides in Portland cement and some minerals present in the aggregate (such as opal, chert, chalcedony, trim it, cristobalite and quartz). Without any reactive aggregate contains reactive silica, high porosity solution of alkalinity and sufficient moisture, there will be no expansion due to ASR.

What is Silica Fume?

2020-1-15Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). The individual particles are extremely small, approximately 1/100th the size of an average cement particle. Because of its fine particles, large surface area, and the high SiO2 content, silica fume is a very reactive pozzolan when used in concrete.

RAW MATERIALS IN CEMENT PRODUCTION

The choice of composition of materials mixture with useful components generally is determined by plant's geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.
