The invention relates to the technical field of building materials, and relates to mortar containing recycled aggregate. The mortar comprises the following components by mass: 15-20 parts of water; 20to 30 parts of Portland cement; 30 to 40 parts of recycled aggregate; 60 to 80 parts of natural aggregate; 15 to 20 parts of nano calcium carbonate; 10 to 15 parts of silica fume; and 1-3 parts of zirconium naphthenate. The invention also relates to a preparation method of the mortar containing recycled aggregate. The preparation method comprises the following steps: (1) pretreatment of recycledaggregate: uniformly mixing recycled aggregate, nano calcium carbonate, silica fume and zirconium naphthenate to obtain a premix; and (2) mixing: sequentially adding Portland cement, water, the premixand natural aggregate into a reaction container, and uniformly stirring and mixing to obtain the mortar containing recycled aggregate. The recycled aggregate does not influence the compression strength and rupture strength after the mortar cures.
本发明涉及建筑材料的技术领域，涉及一种含再生骨料的砂浆，其包括以下质量份数的组分：水15‑20份；硅酸盐水泥20‑30份；再生骨料30‑40份；天然骨料60‑80份；纳米碳酸钙15‑20份；微硅粉10‑15份；环烷酸锆1‑3份。还涉及一种含再生骨料的砂浆的制备方法，包括以下步骤：步骤（1），再生骨料预处理：混合再生骨料、纳米碳酸钙、微硅粉以及环烷酸锆，混合均匀，得预混合料；步骤（2），混合：在反应容器中依次序加入硅酸盐水泥、水、预混合料以及天然骨料，搅拌混合均匀，即得含再生骨料的砂浆。本发明具有再生骨料不容易对砂浆硬化后的抗压强度以及抗折强度造成影响的效果。
