Abstract

The invention relates to an anticorrosion and antirust reinforced concrete, and a microcirculation construction production method thereof, and belongs to the field of building concrete materials. The anticorrosion and antirust reinforced concrete for promoting the structure microcirculation and refinement of a concrete aggregate compound and enhancing the interface combination and the density comprises, by weight, 160 parts of Portland cement, 90 parts of broken stones, 60 parts of fine sands, 30 parts of calcium chloride, 12 parts of magnesium silicate, 10 parts of active calcium silicate, 8 parts of sorbose calcium, 9 parts of dialuminum hydrogen phosphate, 6 parts of strontium oxide, 8 parts of brucite powder, 18 parts of fly ash, 4 parts of white clay powder, 12 parts of silica micro-powder, 6 parts of polyvinyl alcohol, 15 parts of phosphogypsum, 5 parts of lithium 12-hydroxystearate, 6 parts of potassium tripolyphosphate, 5 parts of sodium allyl sulfonate, 2 parts of a water reducer, 2 parts of an expanding agent, 15 parts of barium hydroxide and a proper amount of water. The anticorrosion and antirust reinforced concrete has excellent impact, compression, tensile, crack, corrosion and rust resistance.

Description

technical field [0001] The invention relates to the field of building concrete materials, in particular to an anti-corrosion and anti-rust reinforced concrete material that promotes structural microcirculation and refinement and a selective construction preparation method thereof. Background technique [0002] Concrete and reinforced concrete are widely used in infrastructure projects such as buildings, bridges, dams, urban traffic, seaport terminals, etc. With the frequent occurrence of El Niño extreme weather, various geological and meteorological disasters have caused great damage to the human ecological environment. Humidity, high salinity, high alkali, and smog seriously threaten the safety of these infrastructures. The reinforced concrete structure is impacted by the external environment, so that the performance indicators of the concrete, such as durability, corrosion resistance, waterproof and impermeability, fire and explosion resistance, crack resistance and heat p...
