Micro silica

Introduction of Mega "Gel" products
Our mega "gel" products are produced on the basis of "microsilica", which after being added to concrete is combined with "calcium hydroxide" resulting from cement "hydration" reactions and leads to the production of strong silicate structures.

Relying on the technical expertise of our experts, in order to make the best use of "micro silica" in concrete and eliminate the problems of direct use of these materials in powder form, we have developed and produced it as a "micro silica slurry".

Notable civil engineers:
Why is micro silicate a cement supplement?
Hello dear colleagues,
One of the main problems of concrete structures is their resistance to chemical attacks such as
chlorine ions, sulfates, etc. on the shores of the seas. Protecting the connections (rebar’s) has
always been a problem for project employers.
Today, most consulting engineers in the construction industry recommend the use of "microsilica powder" with Super Plasticizer in concrete construction. Because scientific experiments
have shown that the presence of "micro silica" or (silicon smoke - Silica fume, also known as
micro silica, CAS number 69012-64-2, EINECS number 273-761-1, is an amorphous “noncrystalline” polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a byproduct of the silicon and ferrosilicon alloy production and consists of spherical particles with
an average particle diameter of 150 nm This makes it approximately 100 times smaller than
the average cement particle.) in cement mortar 7% in concrete significantly prevents the
pe*******on of chlorine ions. Micro silica (Silica Fume) meeting the requirements of ASTM C
1240, EN 13263, JIS A 6207 and ISIRI 13278.
