摘要
对表面带槽蒸压粉煤灰砖试块进行了连续110d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。研究结果可为我国蒸压粉煤灰砖在工程中的应用提供参考依据。
On the basis of the test on the dry shrinkage performance of autoclaved flyash combed bricks cured in standard environment and natural environment for 110 days, the main factors for affecting the dry shrinkage performance, such as the ambient temperature, the relative humidity and the curing ages are analyzed. The formulas which estimates the dry shrinkage performance are put forward. The research results can provide a reference for utilization of autoclaved fly ash bricks in engineering.
