纳米SiO2对聚合物改性水泥基材料性能的影响
Influence of nano-SiO2 on polymer-modified cement-based materials
摘要
Abstract
The workability, setting time, and mechanical properties of polymer-modified mortar with nano-SiO2 were tested. The Influence of nano-SiO2 on hydration behavior of polymer-modified cement-based materials was studied using microcalorimetry. Microstructure was observed by scanning electron microscope. The test results show that the fluidity is improved, the hydration reactions of polymer modified cement-based materials are postponed, the setting time is shortened. The interface transition zone between aggregate and cement paste, and the hydration production structure are effectively improved.关键词
