Micro silica (RAH) is an amorphous polymorph of silica (SiO2 / silicon di-oxide). It is also known as silica fume or condensed silica fume. It is an ultrafine powder collected as a by-product during the production of the silicon and ferrosilicon alloys.  It consists of spherical particles having an average diameter of 150nm. The main field application is as pozzolanic material for high performance concrete.It is uniquely pure and efficient.  When used as an additive for the concrete, micro silica dramatically improves the durability and shelf life of concrete, thus saving the maintenance costs. RAH as a pozzolanic reactive material can be used to improve surface area of transition zone between the microscopic stucture of cement paste and aggregate in the high performance concrete. Particle size of 0.03 - 0.1 microns.
