指出植物纤维具有环保节能、保温防火、轻体防雷等优点，将其掺入混凝土中可以改善其脆性，延缓开裂，改变水泥基稻草纤维复合材料的水灰比和纤灰比并加入 CaCl2作为外加剂来制作试件，通过测量试件的静曲强度和观察试件断面的显微图像来确定最优配合比，并分析了 CaCl2对稻草纤维水泥基复合板材的微观影响，得出了一些结论。%Point out plant fibers have lots of advantage such as:fire prevention,environmental protection,energy conservation,heat preserva-tion,light and lightning protection. Incorporated in the concrete can improve its brittleness and delay cracking. Change water cement ratio of ce-ment matrix straw fiber composites and fiber cement ratio to make the specimen. In addition,joining CaCl2 as admixture,measured in the cross section of the specimen static music intensity,observed the microscopic image of specimen to determine the optimal mixture ratio and analysis the micro impact of CaCl2 for straw fiber cement matrix composite,obtains some conclusions.
