Methods: The surface hardness, compressstrength, diametral tensile strength of composites were measured.
方法：测定材料的硬度、压缩强度、径向拉伸强度。

Through adding low viscidity Hydroxypropyl Methyl Cellulose, workable performance of the dry mix can be most improved, but compressstrength reduce.
通过掺入低粘度的羟丙基甲基纤维素后，砂浆的施工和易性能得到了极大的改善，但强度有所降低。

RESULTS: The effect of fixation strength, stiffness, stability and ultimate compressstrength by GCC is better than that of general compress plate (GCP).
