Expansive concrete repair mortar in marine environment and preparation method thereof
The invention relates to expansive concrete repair mortar in a marine environment and a preparation method thereof. The expansive concrete repair mortar comprises a rubber material, an additive and aggregate, the adhesive material is prepared from the following components in parts by mass: 100 to 120 parts of superfine cement, 20 to 40 parts of superfine mineral powder, 20 to 50 parts of ardealite, 10 to 20 parts of fly ash microbeads and 10 to 20 parts of silica fume. The admixture comprises the following components in parts by mass: 3-6 parts of latex powder, 1-3 parts of a water reducing agent and 0.5-2 parts of an early strength agent; the aggregate comprises quartz sand, common light aggregate and superfine light aggregate, and the total mass fraction of all the components in the aggregate is equal to the total mass fraction of all the components in the rubber material; in the aggregate, the volume percent of the superfine light aggregate is 5%-10%, the volume percent of the common light aggregate is 5%-20%, and the volume percent of the quartz sand is 70%-90%. According to the invention, the negative influence of phosphogypsum on mortar in the prior art can be solved.
本申请涉及一种海洋环境下膨胀型混凝土修补砂浆及制备方法，其包括胶材、外加剂和集料；按照质量份计，所述胶材包括：超细水泥100‑120份、超细矿粉20‑40份、磷石膏20‑50份、粉煤灰微珠10‑20份、硅灰10‑20份；按照质量份计，所述外加剂包括：乳胶粉3‑6份、减水剂1‑3份、早强剂0.5‑2份；所述集料包括石英砂、普通轻集料和超细轻集料，所述集料中各成分的总质量份数与所述胶材中各成分的总质量份数相等；在所述集料中，所述超细轻集料的体积百分比为5％～10％，普通轻集料的体积百分比为5％～20％，石英砂的体积百分比为70％～90％。本申请可以解决相关技术中磷石膏对砂浆造成的负面影响。
