Nano-enhanced internal curing sulfate-slag-resistant concrete and preparation method thereof
The invention provides nano-reinforced internal curing sulfate-resistant cave slag concrete and a preparation method thereof, and relates to the technical field of building materials, and the nano-reinforced internal curing sulfate-resistant cave slag concrete comprises the following raw materials in parts by weight: 100-500 parts of Portland cement, 30-300 parts of cave slag stone powder, 1000-1500 parts of fine aggregate, 1-5 parts of nano Fe2O3, 0.5-2 parts of water-absorbent resin, 3-5 parts of barium hydroxide and 200-300 parts of water. The nano-reinforced internal curing sulfate-resistant cave slag concrete provided by the invention realizes the replacement of the cave slag stone powder to cement, can effectively reduce CO2 emission, has the characteristics of good mechanical properties and working properties, excellent sulfate corrosion resistance and the like, improves the service performance of a concrete structure, greatly prolongs the service life of a building, and is suitable for large-scale production. And the method is particularly suitable for engineering construction with high requirements on the service life of buildings, such as bridge engineering.
本发明提供一种纳米增强内养护抗硫酸盐洞渣混凝土及其制备方法，涉及建筑材料技术领域，按重量份计，所述混凝土的原料包括：硅酸盐水泥100～500份、洞渣石粉30～300份、细骨料1000～1500份、纳米Fe2O31～5份、吸水性树脂0.5～2份、氢氧化钡3～5份和水200～300份。本发明所提供的纳米增强内养护抗硫酸盐洞渣混凝土实现了洞渣石粉对水泥的替代，能够有效降低CO2排放，并具有良好的力学性能和工作性能，优异的抗硫酸盐侵蚀性能等特点，提高了混凝土结构的服役性能，使建筑物使用寿命大幅提高，特别适用于桥梁工程等对建筑物寿命有较高要求的工程施工。
