摘要
掺一定量的硅粉可以抑制碱骨料反应(ASR)的膨胀变形。从硅粉抑制ASR的能力,抑制ASR膨胀的程度以及抑制ASR膨胀的工程安全性等三个方面,对掺硅粉抑制骨料ASR的有效性进行评估,评估结果表明:掺8%硅粉能够有效的抑制骨料的ASR膨胀。
Doped a certain amount of silica fume can inhibit the expansion of ASR deformation. The author describes the evaluation of effectiveness of silica fume on suppressing ASR expansion including the strength of silica fume in suppressing ASR expansion, degree and safety of silica fume in suppressing ASR expansion.the results of evaluation shows that: a mix ratio of 8% of silica fume may be quite adequate.
