Abstract

As construction waste, waste glass has great harm to the environment. It is essential to find an effective method to reuse waste glass. In this paper, the effect of glass powder on the performance of concrete is studied. The results show that the addition of glass powder leads to the increase of friction and the deterioration of working performance. ICP and TG show that the early volcanic ash effect of glass powder is not obvious. The addition of glass powder reduces the early compressive strength, but with the increase of age, the compressive strength of concrete increases. Through MIP, UPV and SEM-EDS, it is shown that with ageing, the addition of glass powder improves durability and no significant difference in hydration products is observed. Thus, the addition of glass powder can provide good economic and environmental benefits. Therefore, glass powder can be mixed according to actual engineering needs.

不同替代率玻璃粉对混凝土性能影响的微观机理分析
废玻璃作为建筑垃圾,对环境危害很大。找到一种有效的方法来再利用废玻璃是很重要的。本文研究了玻璃粉对混凝土性能的影响。结果表明,玻璃粉的加入导致摩擦增大,工作性能下降。ICP和TG表明玻璃粉的早期火山灰效应不明显。玻璃粉的加入降低了混凝土的早期抗压强度,但随着龄期的增加,混凝土的抗压强度增加。MIP、UPV和SEM-EDS分析表明,随着老化,玻璃粉的加入提高了材料的耐久性,水化产物无显著差异。因此,添加玻璃粉可以提供良好的经济效益和环境效益。因此,玻璃粉末可根据实际工程需要进行混合。
