摘要
按照GB/T2542-2003《砌墙砖试验方法》标准中规定的冻融试验方法,对蒸压粉煤灰砖进行抗冻性能试验及计算,常会出现制品冻融后抗压强度反而提高的反常现象。分析认为:《砌墙砖试验方法》标准规定的冻融试验方法不适用于蒸压粉煤灰砖,并就蒸压粉煤灰砖抗冻性能的试验方法提出建议。
The product compressive strength grew by freeze experiment ac-cording to the freeze experiment method in the standard GB/T 2542-2003 'The method of evaluating the fired common brick'. The analysis thought: 'The method of evaluating the fired common brick' is not suitable in auto-claved fly ash brick and put forward the proposal of autoclaved fly ash brick freeze experiment method.
