Embodiment Construction
[0010] Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not limiting, and the protection scope of the present invention cannot be limited by the following examples.
[0011] A concrete micro-crack reinforcement construction method, comprising the following steps:
[0012] (1) The crack width is less than 0.3mm: the cracks below 0.3mm can be automatically repaired by using the characteristics of the permeable crystalline waterproof material. When the base surface is cleaned in place, spray the permeable crystalline waterproof material CM-DPS directly. Realize the repair of cracks below 0.3mm;
[0013] (2) If the width of the crack is within 0.3-0.5mm: expand the crack, and the width of the crack is twice the width of the crack itself; Supplementary alkali treatment, CaOH diluted at a ratio of three thousandths 2 After filling the alkali with water, immediately use CM-DPS to fill the joints; repeat the...
