EMC技术对RPC流动度及强度的影响
Effects of EMC Technology on the Fluidity and Strength of RPC
摘要
Abstract
The Energetically Modified Cement(EMC)is a new technology based on grinding.However, the effects of EMC technology on the performance are unclear.Based on experiments, the effects on the fluidity of RPC by the EMC technology were discussed, as well as the optimal quantity of the water-reducing admixtures used in experiments.Meanwhile, experiments were performed to study the impact on the strength of RPC by the EMC technology, including every age strength and those of Reactive Powder Concrete(RPC) made by different water to binder ratio.The results showed that the EMC technology lowered the RPC fluidity and the optimal quantity of the water-reducing admixtures, which is particalarly obvious for FDN.The compressive strength of RPC in 1 day was increased by 103.4% because of the use of EMC technology, while the value of flexural strength was 27.2%.The corresponding ones in 28 days were 25.1% and 36.6% respectively.Besides, EMC technology reduced the degree of relationship between strength and the water to binder ratio.关键词
