All-component low-carbon concrete capable of absorbing carbon dioxide and preparation method of all-component low-carbon concrete
The invention discloses all-component low-carbon concrete capable of absorbing carbon dioxide and a preparation method of the all-component low-carbon concrete. The all-component low-carbon concrete comprises the following components: cement subjected to carbon absorption treatment; aggregate is recycled; recovering sand; an admixture; hollow glass beads; an additive; an aqueous solution. According to the invention, all the components of the concrete can capture carbon dioxide gas, so that the carbon capture amount of the concrete is greatly increased, the carbon emission of the concrete industry is reduced, and the concrete has important environmental protection significance. After the cement, the recycled aggregate, the recycled sand, the carbon sequestration admixture, the hollow glass beads and the aqueous solution are subjected to high-temperature pressurized carbonization, the absorption of the concrete to carbon dioxide gas is greatly improved, and the performance of the recycled aggregate, the recycled sand and the carbon sequestration admixture is improved, so that the working performance, the mechanical performance and the durability of the concrete are improved. The carbon dioxide gas is wrapped in the hollow glass beads, so that the carbon capture amount is further increased. And meanwhile, the working performance of the concrete can be improved by utilizing a ball bearing effect.
本发明公开了一种全组分吸收二氧化碳低碳混凝土及制备方法，包括如下组分：吸碳处理后的水泥；回收骨料；回收砂；掺合料；空心玻璃微珠；外加剂；水溶液。本发明实现混凝土各组分均可捕集二氧化碳气体，使混凝土碳捕集量大幅提升，减少混凝土行业的碳排放，具有重要的环保意义。当水泥、回收骨料、回收砂、固碳掺合料、空心玻璃微珠、水溶液经过高温加压碳化后即大幅增加了混凝土对二氧化碳气体的吸收，又改善了回收骨料、回收砂、固碳掺合料的性能，进而提升了混凝土的工作性能、力学性能、耐久性能。利用空心玻璃微珠内部包裹二氧化碳气体，进一步增大碳捕集量。同时还能利用滚珠轴承效应，提升混凝土的工作性能。
