Foam concrete equipment and construction Foam concrete is a special kind of aerated concrete. Its pore structure and material properties are close to those of aerated concrete. The difference between the two is only in the shape of pores and the means of aerating. The pores of aerated concrete are generally oval, while foam concrete is deformed and forms polyhedron due to the effect of pores. Aerated concrete uses chemical gas generation -

Application of micro silica powder in concrete construction Micro silica fume, also called silica fume or condensed silica fume, or silica fume, is a by-product produced by the reduction of high-purity quartz, coke and sawdust in the submerged arc furnace during the production of ferrosilicon or metal silicon. The main component is SiO2. Generally, the color of micro silica fume is between light gray and dark gray. SiO2 itself is colorless, and its color mainly depends on the content of carbon and iron oxide. The higher the carbon content, the better the color -
