2021-11-8  The particle size and distribution of SUPPERPOZZ P500 TM is a key characteristic in ensuring the product's superior performance. SUPPERPOZZ P500 TM particles range in size between 0.1 - 30 microns with a mean particle diameter of 3.9 to 5 microns. This is significantly finer than Portland cement, other commonly used cement types and upplementary cementitious materials (SCM).

Al(OH)3 ultrafine powder was extracted from fly ash with the method of dispersing agent-carbonizating. Fly ash is activated by the method of sintering with limestone, so the inert mullite can be convert into C12A7 which can be dissolved in Na2CO3 liquor. The conversion of β-C2S to γ-C2S is accompanied by an increase in volume and results in the self-pulverization of the sintering feed, and ...

2021-6-7  Fly ash ultrafine grinding: Because the microbeads (ultra-fine fly ash) particles are extremely small, they can be added to the concrete to fill the gaps between the cement particles, so that free water can be discharged, and the fluidity of the cement slurry can be increased. Therefore, it can be used to prepare self-compacting concrete.
