MIXING MATERIALS OF CONCRETE OF STRENGTH ENHANCEMENT AND FROST RESISTANCE AND MIXING METHOD OF THE CONCRETE MATERIALS

摘要

The present invention relates to a concrete mixing composition for strength enhancement and frost resistance and a method for mixing concrete. The concrete mixing composition includes a sodium chloride, ammonium chloride, magnesium chloride, soda ash, a surfactant, propylene glycol to increase strength of concrete and increase durability to prevent crack and defect on cross section of concrete caused by frost.
