针对西部盐湖地区耐腐蚀混凝土的需求和结合当地实际情况,设计了在干燥环境下与浸水环境下,通过对相对动弹性模量、相对质量、综合评价参数及扫描电子显微镜试验的研究来判断镁水泥混凝土的性能.通过研究发现:采用无损检测试验方法进行为期一年的试验后发现,镁水泥混凝土的6种配合比中性能最好的配合比是配合比2,而它所用材料的比例为:水∶MgO∶MgCl2∶石子∶砂子∶磷肥∶减水剂=1∶2.87∶1.09∶8.57∶4.61∶0.07∶0.12.
According to the demand of corrosion-resisting concrete in the western salt lake area and combining with the local conditions, the performance of magnesium cement concrete was studied by relative elastic modulus, relative quality, comprehensive evaluation parameters and scanning electron microscope under dry and immersed environment.The results show that the best mix ratio of the six mixes of magnesium cement concrete is mix ratio 2, and the proportion of materials used is: water∶MgO∶MgCl2∶stone∶sand∶phosphate∶water-reducing agent=1∶2.87∶1.09∶8.57∶4.61∶0.07∶0.12, after one year test by nondestructive testing method.
