| abstract |
The invention provides a composite alkali excited lithium slag low-temperature early-strength concrete and a preparation method thereof, which, in parts by weight, comprise 2-14 parts of ultrafine lithium slag slurry, 3-9 parts of nanometer carbide slag slurry, 27-35 parts of parts cement, 2-4 parts calcium sulfate, 0.1-0.2 parts sodium citrate, 65-75 parts fine aggregate, 90-100 parts coarse aggregate, 7-15 parts water, 1.2 parts water reducer, and 0.3 parts antifreeze agent. The present invention selects solid waste as raw material for preparation, which helps to reduce environmental pressure. The prepared concrete has good strength, impermeability and low temperature resistance. It can be widely used in construction concrete in low temperature area. |
