Hydraulic self-healing mortar and preparation method thereof
The invention belongs to the technical field of concrete materials, and particularly relates to hydraulic self-healing mortar and a preparation method thereof. The hydraulic self-healing mortar disclosed by the invention is prepared by mixing the following components in parts by weight: 270-290 parts of a rubber material, 700-750 parts of aggregate, 4-4.5 parts of an additive, 1.5-9 parts of a repairing agent, 100-110 parts of water and fibers accounting for 0.5%-1.2% of the total volume. The preparation method comprises the following four steps: preparing the components, dry-mixing, pulping and forcibly stirring. The prepared mortar is repaired and inspected through the five steps of preparation, die filling, crack reserving, maintenance and repair detection test. The mortar disclosed by the invention has the functions of self-diagnosing cracks and self-repairing the cracks, can provide a new research way for improving the crack resistance of a concrete matrix or reducing existing cracks of concrete, and can also provide guarantee measures for improving the performance of a concrete material, so that the service life of a concrete building is prolonged.
本发明属于混凝土材料技术领域，具体地涉及一种水工自愈合砂浆及其制备方法。本发明的水工自愈合砂浆是由按照如下重量份的胶材270～290份、骨料700～750份、外加剂4～4.5份、修复剂1.5～9份、水100～110份，及占总体积的掺量百分比为0.5％～1.2％纤维混合而成。将上述组成料通过准备、干拌、制浆和强制搅拌四个步骤制备而成。通过制备、装模、预留裂缝、养护和修复检测试验五个步骤对制备的砂浆进行修复检验。本发明的砂浆具有自我诊断裂缝及自我修复裂缝的功能，可为提高混凝土基体抗裂性能或减少混凝土既有裂缝提供新的研究途径，也可为混凝土材料性能提升提供保障措施，进而延长混凝土建筑物使用寿命。
