Manufacturing method of green high-ductility fiber concrete hollow building block
The invention relates to a manufacturing method of a green high-ductility fiber concrete hollow building block. The hollow building block is manufactured by taking high-ductility fiber concrete as a raw material. The high-ductility fiber concrete comprises cement, fly ash, mineral powder, sand, sisal fibers and water, wherein in percentage by mass, the ratio of the cement to the fly ash to the mineral powder to the sand to the water is 1: (0.55-0.70): (0.27-0.35): (0.73-0.9): (0.55-0.65); the total volume of the cement, the fly ash, the mineral powder, the sand and the water after uniform mixing is used as a base number, and the volume mixing amount of the sisal fibers is 0.2-1%. The use amount of the industrial waste slag powder and coal ash is relatively increased, and the use amount ofcement is relatively reduced, so that the prepared high-ductility hollow building block is green and environment-friendly. And the ductility of the cement base is effectively improved by reasonable mineral powder and fly ash mixing amount. Compared with pva, steel fibers and the like which are used as raw materials for providing bridging stress and playing a role in resisting cracking, the sisal fibers are used as main components for improving the cracking resistance and have the advantages of being low in cost and environmentally friendly, and after the sisal fibers are subjected to alkali treatment, the durability can meet engineering requirements.
本发明涉及一种绿色高延性纤维混凝土空心砌块的制作方法，采用高延性纤维混凝土作为原材料制作空心砌块。高延性纤维混凝土的组分为水泥、粉煤灰、矿粉、砂、剑麻纤维和水；其中，按质量百分比计，水泥:粉煤灰:矿粉:砂:水=1:0.55~0.70:0.27~0.35:0.73~0.9:0.55~0.65；以水泥、粉煤灰、矿粉、砂和水混合均匀后的总体积为基数，剑麻纤维的体积掺量为0.2‑1%。相对提高了工业废渣矿渣粉、粉煤灰的使用量，水泥用量的相对减少有利于制成的高延性空心砌块是绿色环保的。合理的矿粉和粉煤灰掺量有效提高水泥基的延性。相比pva，钢纤维等作为提供桥联应力，起阻裂作用的原材料，采用剑麻纤维作为提高阻裂能力主要成分，具备成本较低绿色环保的特点，且剑麻纤维通过碱处理后，耐久性可满足工程需求。
