| 摘 要： | 选用超细矿粉配制水泥基材料,比较了其与普通矿粉对水泥浆体的力学性能影响.分别通过XRD和MIP分析了硬化水泥浆体的水化产物、最可几孔径及孔隙率.分析结果表明,粒径明显偏小的超细矿粉具有较高的火山灰反应活性,1d时水化产物中Ca( OH)2的衍射峰明显低于纯水泥浆体和掺普通矿粉的水泥浆体,超细矿粉能显著促进水泥基材的早龄...

| Abstract: | The early age mechanical performance of cement-based material incorporated with ultra fine slag and ordinary slag were comparatively investigated.The hydration products,pore size and porosity of cement-based material were tested with XRD(X-ray diffraction) and MIP(mercury intrusion porosimetry),respectively.The low peak strength of Ca(OH)2 obtained from XRD analysis show that ultra fine slag with significantly smaller particle size than ordinary slag has higher pozzalanic activity than ordinary slag,which s... |
