CONCRETE MIX FOR MANUFACTURE OF THIN-WALLED PRODUCTS Russian patent published in 2009 - IPC C04B28/02 C04B111/20 C04B111/27 

FIELD: construction.

SUBSTANCE: invention is related to construction materials, namely to compositions for concrete mixes reinforced with basalt fiber for manufacture of thin-walled products in the form of fencing and facing structures, such as facing tiles, ventilated facades, etc. Concrete mix for manufacture of thin-walled products contains Portland cement, basalt fiber with length of 12 mm, superplasticiser based on naphthalene sulfocompounds, water and mineral filler in the form of granite crushed stone sifting with fraction of 2-5 mm and sand with size module of 1-2.5, in ratio of 7:3 at the following ratio of components, wt %: Portland cement - 28.50-31.50, basalt fiber with length of 12 mm - 1.39-1.61, superplasticiser based on naphthalene sulfocompounds - 0.29-0.31, water -5.40-6.00, mineral filler - sifted granite crushed stone of fraction 2-5 mm and sand with size module of 1-2.5 - the rest.

EFFECT: higher strength for compression and tension in bending, frost resistance and water impermeability of thin-walled products.
