摘　　要：对蒸压粉煤灰砖试块进行了连续100 d干燥收缩变形的试验研究。通过对其在标准养护和自然养护环境中收缩性能的研究,分析了环境温度、相对湿度及龄期等因素对蒸压粉煤灰砖收缩变形的影响,并提出了考虑这些因素的蒸压粉煤灰砖收缩变形估算公式。研究结果可为蒸压粉煤灰砖在工程中的应用提供参考依据。Based on the test results for the dry shrinkage deformation of autoclaved flyash-lime bricks cured in the standard environment and the natural environment within 100 days,the main factors affecting the dry shrinkage deformation such as the am- bient temperature,the relative humidity and the curing ages are discussed and analyzed. The formulas which estimated the dry shrinkage deformation of autoclaved flyash-lime bricks are suggested, and this may be as a reference for the application of auto- claved flyash-lime bricks in engineering.
