Ultra-super Pozzofine M-500 (Silica Fumes) is a very high-efficiency pozzolanic material for use as a component of cement with Portland cement to yield High-Performance Concrete.

Ultra-Super Pozzofine M-500 is New Age Product with High Activity Index. It is produced by careful selection, processing, and testing of fly ash. In the course of the process, it acquires pozzolanic and self-cementing properties and Very High Content of active silica and alumina which give to improve extra Strength gaining and improve durability of concrete. The size of the particles is Very Fine in Size between 0.1 - 30 microns Fineness % retained on 45 microns is 0% this is the key factor in ensuring the product's superior performance. As it is a top-of-the-range product in terms of all the International Standard specifications for fly ash and is subjected to stringent quality control. They are also being used as a partial replacement for the cement, in the range of 50% to 70% (Depending on the mixture of proportions used). It enhances resistance to sulphate attack, controls alkali-silica reactivity, and reduces permeability.
