Self-repairing cement-based material and preparation method thereof
The invention relates to a self-repairing cement-based material and a preparation method thereof, and belongs to the technical field of self-repairing materials. The self-repairing cement-based material comprises liquid metal besides the material composition of the cement-based material, the cement-based material is cement paste, cement mortar or common concrete, and the liquid metal is low-melting-point metal, comprises indium, tin, lead, bismuth, zinc, antimony, cesium, francium and alloys thereof, and also comprises alloys containing lithium, sodium, potassium and rubidium. The invention provides a double-channel cement-based material self-repairing technology by introducing liquid metal into the mix proportion design of a cement-based material and targeting cracks.
本发明涉及一种自修复水泥基材料及其制备方法，属于自修复材料技术领域。该自修复水泥基材料，除了水泥基材料的物质组成外，还包括液态金属，所述水泥基材料为水泥净浆、水泥砂浆或普通混凝土，所述液态金属为低熔点金属，包括铟、锡、铅、铋、锌、锑、铯、钫及其合金，亦包括含有锂、钠、钾和铷的合金。本发明是在水泥基材料配合比设计中引入液态金属，以裂缝为靶向，提出了“双渠道”水泥基材料自修复技术。
