Preparation and application of dry-mixed self-compacting fine aggregate concrete for repairing
The invention relates to preparation and application of dry-mixed self-compacting fine aggregate concrete for repairing. The dry-mixed self-compacting fine aggregate concrete comprises the following raw materials in parts by weight: 300-420 parts of cement, 500-600 parts of machine-made sand, 200-500 parts of gravel, 120-170 parts of fly ash and 1-1.25 parts of a water reducing agent. The cement mortar has the advantages of good filling performance, high volume stability, micro-expansion without shrinkage, rapid setting and hardening at low temperature and high middle and later strength.
本发明涉及一种修补用干混自密实细石混凝土制备及应用，它包括以下重量份数的原料：水泥300~420份，机制砂500~600份，碎石200~500份，粉煤灰120~170，减水剂1~1.25份；本发明具有填充性良好能、体积稳定性高、微膨胀不收缩、低温下快速凝结硬化、中后期强度大的优点。
