本文通过对加气混凝土各方面性能的分析,从加气混凝土含气量、抗压强度、抗冻性、气泡特征几个方面测定实验数据,结果表明:加气混凝土硬化后含气量降低,硬化混凝土含气量随新拌混凝土含气量的增加而增大;引气剂的加入提高了混凝土的抗冻性,降低了混凝土的强度。预应力混凝土加入引气剂后应力损失增大,气泡间距系数对混凝土抗冻性影响较大。
In this paper, the performance of aerated concrete in various aspects of performance analysis, from aerated concrete gas content, compressive strength, frost resistance, bubble characteristics of several experimental data, the results show that: aerated concrete hardened gas content decreased, hardened concrete Air content increases with the increase of air content of fresh concrete; the addition of air entraining agent increases the frost resistance of concrete and reduces the strength of concrete. After adding pre-stressed air entraining agent, the stress loss increases, and the coefficient of bubble spacing has a great influence on frost resistance of concrete.
