Repair mortar for concrete member and preparation method thereof
The invention discloses repair mortar for a concrete member and a preparation method thereof, which relate to the technical field of cement-based mortar. The repair mortar for the concrete member is mainly prepared from an additive and 1060 parts by weight of an internal admixture. The additive comprises the following raw materials in parts by weight based on the total weight of the repair mortar: 0.5-1.5 parts of a defoaming agent, 20-30 parts of an expanding agent, 25-35 parts of rubber powder and 8-12 parts of a water reducing agent; the internal admixture comprises the following raw materials in parts by weight based on the total weight of the internal admixture: 85-105 parts of water, 390-420 parts of cement, 20-35 parts of silica fume, 20-35 parts of an accelerator and 450-550 parts of graded sand. The repair mortar has the advantage of high bonding strength. The preparation method comprises the following steps of material mixing, sand mixing, mortar preparation and the like. The preparation method has the advantage that the bonding strength of the product can be improved.
本申请公开了一种用于混凝土构件的修补砂浆及其制备方法，涉及水泥基砂浆技术领域。一种用于混凝土构件的修补砂浆，主要由外加剂和1060重量份的内掺料制成，所述外加剂包括基于修补砂浆总重量计的以下重量份原料：消泡剂0.5‑1.5份，膨胀剂20‑30份，胶粉25‑35份，减水剂8‑12份；所述内掺料包括基于内掺料总重量计的以下重量份原料：水85‑105份，水泥390‑420份，硅灰20‑35份，速凝剂20‑35份，级配砂450‑550份。其具有粘结强度高的优点。其制备方法包括以下步骤：掺料、混砂和砂浆制备等；其制备方法具有可改善产品粘结强度的优点。
