Anti-freezing concrete composition and preparation method thereof
The invention relates to the technical field of concrete compositions, in particular to an anti-freezing concrete composition and a preparation method thereof. The invention discloses an anti-freezingconcrete composition. The concrete comprises the following components in parts by weight: 100-120 parts of Portland cement, 160-220 parts of gravels, 130-150 parts of sand, 25-35 parts of fly ash, 55-75 parts of water, 5-8 parts of polypropylene fibers, 11-16 parts of a composite antifreeze agent, 0.2-0.4 part of an air entraining agent, 10-15 parts of an additive and 2-5 parts of a composite water reducing agent. The anti-freezing concrete composition has good freezing resistance, strength and impermeability, can meet engineering requirements on durability and use safety of concrete under alow-temperature condition, and is simple and efficient in preparation method, convenient to operate and control, stable in product quality and beneficial to industrial production.
