METHOD TO PRODUCE HIGH-STRENGTH CONCRETE MORTARS

摘要

FIELD: construction.SUBSTANCE: portland cement, crushed stone and sand are mixed, additionally they add cooled keratin protein polymer (produced in the following manner: they take 100 kg of horns and hoofs, pour with 3.0% alkaline solution of NaOH at the ratio of 1:10 and heat in a reservoir at temperature of 121°C for 6 hours to produce keratin protein polymer made of 84% protein, 15% polypeptides and less than 1% of amino acids on dry basis, balance - water.EFFECT: increased strength of concrete and production of environmentally safe products.
