本文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为代表的低标号自密实混凝土的新概念及解决方案─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600~670mm,1hr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。
Based on the characteristics of raw material and concrete market in our country and based on the new technology of RheoMATRIX admixture based on BASF’s proprietary intellectual property, this paper proposes a new concept and solution of low-grade self-compacting concrete represented by C30 ── Smart Dynamic Concrete (SDC) ). The design parameters of intelligent dynamic concrete: the total amount of cementitious material is less than 380kg / m3, the initial fluidity is 600-670mm, the fluidity of 1hr is not less than 600mm, T50 is no more than 12s, no bleeding and segregation phenomenon. A large number of tests show that intelligent dynamic concrete in the Chinese market has a wide range of promotion and application prospects.
