Preparation method of anti-cracking concrete for outer wall
The invention belongs to the technical field of concrete processing and manufacturing, and particularly relates to a preparation method of anti-dry-crack type outer wall concrete, which is prepared from the following raw materials in parts by weight: 50 to 90 parts of Portland fly ash cement, 17 to 33 parts of mineral powder, 7 to 11 parts of calcium lignosulphonate, 70 to 86 parts of gravel, 70 to 90 parts of quartz sand, 15 to 20 parts of polypropylene fiber, 13 to 15 parts of steel fiber, 10 to 15 parts of carbon fiber, 18 to 30 parts of mortar reinforcing agent and 100 to 180 parts of clear water. The prepared concrete product has the advantages of high bonding strength, high shrinkage resistance, high bonding force, stable performance and the like, the processing and preparation device can improve the viscosity of the concrete, so that the concrete is more uniformly mixed together, the proportion of each part of the concrete is more uniform, the impermeability and durability of the concrete are effectively improved, the construction quality can be improved, and the construction cost is reduced. The construction cost is saved, the waterproof function of the outer wall cover of the building is improved, the service life of the building is prolonged, and good economic benefits and social benefits are generated.
本发明属于混凝土加工制造技术领域，具体涉及一种抗干裂式外墙用混凝土制备方法，其各原料重量组份为：粉煤灰硅酸盐水泥50～90份、矿粉17～33份、木质素磺酸钙7～11份、碎石70～86份、石英砂70～90份、聚丙烯纤维15～20份、钢纤维13～15份、碳纤维10～15份、砂浆增强剂18～30份和清水100～180份；制得的混凝土产品粘合强度高、抗收缩性能强、粘结力强、性能稳定等优点，加工制备装置能够使混凝土粘性变高，使混凝土更加均匀的混合在一起，使各部分混凝土配比更加均匀，有效地提高混凝土的抗渗性和耐久性，并能提高施工质量，节约施工成本，提升建筑物外墙封皮的防水功能，增加建筑物的使用寿命，产生良好的经济效益和社会效益。
