Abstract:
     The production method of aluminosilicate mineral superfine powder belongs to the field of building material technology, and uses kaolin as raw material and includes the following steps: heating said raw material for 1-2 hr. at 600-800 deg.C to obtain metakaolin; mixing raw material kaolin and water-reducing agent according to a certain weight percentage, uniformly stirring and drying to obtain adjuvant; uniformly mixing the metakaolin and adjuvant according to a certain ratio, grinding so as to obtain the invented product. Said product can change concrete composition, improve concrete structure, and can effectively inhibit internal pathological changes of concrete, and can protect concrete against external corrosion.
