研究了稻壳灰对含石灰石粉水泥浆体碳硫硅钙石形成的影响。将粗稻壳灰（CRHA）和细稻壳灰（FRHA）按不同比例掺入水泥中，制备2%MgSO4溶液养护的试件。每月检查迫击炮的外观变化。抗压强度，长度和质量的发展作为时间的函数进行了检查。用X射线衍射、傅里叶变换红外光谱和激光拉曼光谱对硫酸盐侵蚀产物进行了表征。结果表明，用RHA部分取代水泥，可延缓水泥混凝土的劣化程度。使用FRHA表现出更好的性能比那些粗糙的。含20%FRHA的砂浆在MgSO4溶液中浸泡12个月后，未观察到明显的退化。
The influence of rice husk ash (RHA) on the thaumasite formation of cement pastes containing limestone powder was investigated. The specimens which were cured in 2 % MgSO4solution were prepared with different ratios of coarse rice husk ash (CRHA) and fine rice husk ash (FRHA) to cement. The visual change of mortars was inspected monthly. Compressive strength, length and mass developments were examined as functions of time. The products of sulfate attack were examined by X-ray diffraction, Fourier transform infrared spectroscopy and Laser-Raman spectroscopy. The results showed that the degree of deterioration was retarded when cement was partially replaced by RHA. The use of FRHA showed better performance than those of the coarser ones. No obvious degeneration was observed in the mortar contains 20 % FRHA after 12 months of immersing in the MgSO4solution.
