Municipal bridge concrete polymer machine-spraying quick-setting repair mortar
The invention discloses a municipal bridge concrete polymer machine-spraying quick-setting repair mortar, which belongs to the technical field of repair mortar, and comprises the following components: 300-500 parts of ordinary Portland cement, 0-150 parts of sulphoaluminate cement, 300-700 parts of quartz sand, and 10-100 parts of fly ash. The polymer repair mortar is prepared from the following components in parts by weight: 10-50 parts of redispersible latex powder, 0.5-5 parts of a water reducing agent, 1-4 parts of wood fibers, 0.2-8 parts of cellulose ether, 0.1-3 parts of starch ether, 0.1-3 parts of an air entraining agent, 0.5-8 parts of a rheological agent and 1-15 parts of waterproof powder, cement is used as a basic binding agent, a high-strength material (quartz sand) is used as a main aggregate, and the polymer repair mortar is prepared by modifying a high-molecular polymer. And an anti-cracking agent, a rheological agent, a waterproof agent and the like are used as auxiliary materials to prepare the special concrete repairing material. The product has the advantages of good smoothness, strong waterproofness, high strength and no shrinkage; the paint has the characteristics of no toxicity, harmlessness, no aging, no pollution to water quality and surrounding environment, good self-sealing performance, rust resistance and the like.
本发明公开了一种市政桥梁混凝土聚合物机喷速凝修补砂浆，属于修补砂浆技术领域，聚合物修补砂浆的组分如下，普通硅酸盐水泥300‑500份、硫铝酸盐水泥0‑150份、石英砂300‑700份、粉煤灰10‑100份，可再分散乳胶粉10‑50份、减水剂0.5‑5份、木质纤维1‑4份、纤维素醚0.2‑8份、淀粉醚0.1‑3份、引气剂0.1‑3份、流变剂0.5‑8份、防水粉1‑15份，聚合物修补砂浆以水泥为基础结合剂，高强度材料(石英砂)作为主骨料，通过高分子聚合物改性，辅以抗裂剂、流变剂、防水剂等物质配制而成的混凝土特种修补材料。本产品具有平整性好，防水性强，强度高、无收缩；无毒、无害、不老化、对水质及周围环境无污染，自密性好、阻锈等特点。
