摘要
将稻草原材料制成不同粒径的微粒,并分别按不同掺量制成复合砂浆,通过试验得到复合砂浆抗折强度、抗压强度、干缩率以及导热系数变化规律。研究结果表明,稻草纤维微粒能有效改善砂浆物理力学性能,为节能环保起到有效的推动作用。
The different size of particle is produced by straw raw material, composite mortar is made of different dosage of particle. The change rules of the flexural strength, compressive strength, dry shrinkage and thermal conductivity variation of composite mortar is obtained by experiment. The results show that, the straw fiber particle can effectively improve the physical and mechanical properties of the mortar,which can promote the energy saving and environmental protection.
