摘要：
Self-compacting concrete (SCC) mixes were cast which contained different w/b ratio changing stepwise from 0.42 down to 0.29, and also different silica fume content, 0%; 6% and 12% (by weight) on a cement replacement basis. SCC turned out to be frost resistant at w/b ratio around 0.34 but increasing silica content did not improve the frost resistance and therefore the w/b ratio 0.30 has to be established for silica fume content of 12%. Rheological measurements on fresh concrete as well as compressive strength on hardened concrete were also carried out.
