Composite admixture as well as preparation method and application thereof
The invention relates to the field of building materials, and particularly discloses a composite admixture and a preparation method and application thereof.The composite admixture is prepared from, by weight, 4-16 parts of a defoaming agent, 2-10 parts of a water reducing agent, 1-5 parts of a dispersing agent, 10-20 parts of modified rubber powder, 5-15 parts of water and 3-21 parts of isopropanol; the modified rubber powder is konjac glucomannan modified rubber powder, after the modified rubber powder is applied to cement, the breaking strength of the obtained cement in 3d and 28d is 5.8 MPa and 10.3 MPa at most, the compressive strength of the cement in 3d and 28d is 24.7 MPa and 65.2 MPa at most, and the modified rubber powder has high mechanical strength.
本申请涉及建筑材料领域，具体公开了一种复合外加剂及其制备方法和应用，其中，一种复合外加剂，包括如下重量份原料：消泡剂4‑16份，减水剂2‑10份，分散剂1‑5份，改性橡胶粉10‑20份，水5‑15份，异丙醇3‑21份；所述改性橡胶粉为魔芋葡甘聚糖改性橡胶粉，将其应用到水泥中后，得到的水泥的3d、28d的抗折强度最高分别为5.8MPa和10.3MPa，3d、28d的抗压强度最高分别为24.7MPa和65.2MPa，具有较高的力学强度。
