智能动力混凝土--低强度普通混凝土高性能化的探索与实践(一)

Smart dynamic concrete-exploration and practice in high-performance of low-grade ordinary concrete

结合我国原材料和混凝土市场的特点,基于巴斯夫自主知识产权的RheoMATRIX外加剂新技术,提出了以C30为代表的低强度等级普通混凝土的高性能化的概念及解决方案——智能动力混凝土(Smart Dynamic ConcreteTM,SDC)。智能动力混凝土的设计参数:胶凝材料总量低于380kg/m3,初始流动度600～700mm,1h的流动度不小于600mm,T50不超过12s,无泌水、离析现象。大量的试验证明,智能动力混凝土在中国市场上具有广泛的推广应用前景。

In this paper, the concept and solution about high-performance of low-grade ordinary concrete have been proposed as smart dynamic concrete （ SDC）,which based on BASF proprietary admixture technology-RheoMATRIX , and combined with the characteristics of Chinese raw material and concrete market.Some important design parameters of SDC are fixed as follows：The total binder contents are not more than 380 kg/m^3. The slump flow should be in the range of 600 to 700 mm immediately after mixing and at least 600mrn after one hour, with less than 12 second T50 value, and no bleeding and segregation.A large number of tests have proved broad promotion and application prospects of SDC in China market.
