摘 要:通过湿变环境下水泥生土砌块的吸湿性和膨胀变形,研究了水泥生土砌块的吸湿特性和膨胀变形的作用机理及其力学性能与环境湿度的关系。研究结果表明,水泥生土砌块的吸湿量与膨胀量远小于素生土砌块的吸湿量与膨胀量,且在同一湿度的不可逆收缩变小。随着环境相对湿度的升高,水泥生土砌块的抗压强度逐渐降低。水泥掺入可以显著改善湿度对砌块抗压强度的影响。 Abstract: Relationship between environmental humidity and mechanism and mechanical properties of absorption characteristic of cement raw soil block and expansion deformation of cement raw soil block were studied through absorption of cement raw soil block and expansion deformation under the condition of humidity variation. The results show that, the moisture absorption and expansion of cement block is much less than that of raw block, and irreversible shrinkage become smaller at the same humidity. With the increase of environmental relative humidity, compressive strength of cement raw soil block is gradually reduced. The influence of humidity on compressive strength of block can significantly improved by mixing cement.

(1)随着水泥掺量的增多,水泥生土砌块的吸湿量与膨胀量远小于纯生土砌块的吸湿量与膨胀量,且在同一湿度的不可逆收缩变小。
(2)水泥生土砌块的吸湿量与膨胀量关系曲线的变化趋势大致相同,但是水泥生土砌块与素生土砌块相比,相同吸湿量下,其膨胀量均显著下降。在相同吸湿量时,生土砌块的膨胀量随着水泥掺量的增多而减少。
(3)水泥掺量较小时,对砌块的抗压强度影响不大,只有较多水泥时,才会明显提高砌块的抗压强度。随着环境相对湿度的升高,水泥生土砌块的抗压强度逐渐降低。水泥掺入可以显著改善湿度对砌块抗压强度的影响。
