摘要
本文用国标和ASTMC1 2 0 2方法测试掺加不同外加剂的混凝土抗渗性能 ,测试结果表明ASTMC1 2 0 2方法夸大了掺粉煤灰、硅灰混凝土的抗渗性能。水压加压方法真实的反映混凝土的抗渗性能。
The methods of GBJ82-85 and ASTMC1202 for measuring permeability of concrete were used.The concrete contains fly ash,slag silica fume,expansive agent,dula fibre.The result indicates that the ASTMC1202 method overdrew to resist permeability of concrete containing fly ash,lowered to resist permeability of concrete containing expansive agent;dula fibre cannot lower concrete permeability.
