Anti-cracking high-strength coral mortar and preparation method thereof
The invention relates to the technical field of building mortar, and discloses an anti-crack high-strength coral mortar and a preparation method thereof, the mortar is prepared from the following raw materials by weight: 1220-1280 parts of coral sand; 480 to 560 parts of cement; 95 to 140 parts of industrial waste residue; 3.1 to 5.1 parts of an additive; 4.8 to 7.5 parts of a polymer; 3.8 to 6.1 parts of fiber; 250 to 280 parts of seawater; the coral sand is used as a fine aggregate, the industrial waste residue comprises slag powder, fly ash and silica fume, and the slag powder accounts for 70-75% of the total mass of the industrial waste residue. According to the invention, through scientific proportioning and optimization, the adverse effect of high brittleness of coral sand on the mortar strength is solved, so that the obtained coral mortar has good workability, the compressive strength is 70 MPa or above, the safety and reliability of a building structure can be ensured, and the engineering purpose of crack resistance is realized.
本发明涉及建筑砂浆技术领域，公开了一种抗裂高强型珊瑚砂浆及其制备方法，该砂浆是由以下重量份数配比的原料制备而成：珊瑚砂：1220～1280份；水泥：480～560份；工业废渣：95～140份；外加剂：3.1～5.1份；聚合物：4.8～7.5份；纤维：3.8～6.1份；海水：250～280份；所述珊瑚砂作为细集料，工业废渣包括矿渣粉、粉煤灰和硅灰，其中矿渣粉用量占工业废渣总质量的70～75％。本发明通过科学的配比与优化，解决了由于珊瑚砂脆性大对砂浆强度造成的不利影响，使所得珊瑚砂浆具有良好工作性的同时，抗压强度在70MPa以上，能够保证建筑结构的安全性和可靠性，并实现了阻裂的工程目的。
