Environment-friendly modified straw fiber recycled fine aggregate cement-based composite material and preparation method thereof
The invention provides an environment-friendly modified straw fiber recycled fine aggregate cement-based composite material and a preparation method thereof. The composite material comprises water, cement, modified straw fibers and fine aggregate, wherein a mass ratio of the water to the cement to the fine aggregate is 1: 1: 5, and the modified straw fibers account for 0.2%-1% of the mass of the cement based on the use amount of the cement; and the fine aggregate is composed of recycled fine aggregate and river sand, the weight of the recycled fine aggregate accounts for 25%-75% of the weightof the fine aggregate, and the balance is the river sand. The composite material has the advantages of better compressive strength, frost resistance, bending strength and crack resistance, so the application range of the concrete is enlarged to a great extent; and the preparation method is simple, production cost is saved, and product stability is ensured.
本发明提供一种环保型改性秸秆纤维再生细骨料水泥基复合材料及其制备方法，所述的复合材料组成包括水、水泥、改性秸秆纤维和细骨料，所述的水、水泥、细骨料的质量比为1:1:5，所述的改性秸秆纤维以水泥的用量为参考来计算，改性秸秆纤维为水泥质量的0.2％～1％；所述的细骨料由再生细骨料和河沙组成，再生细骨料占细骨料重量的25％～75％，其余为河沙。具有抗压强度、抗冻性能、抗弯强度和抗裂性能更好的优势，使其应用范围很大程度上增加；其制备方法简单，节省生产成本，保证了产品的稳定性。
