Glass aggregate for inhibiting alkali-aggregate reaction and preparation method thereof
The invention discloses a glass aggregate for inhibiting alkali-aggregate reaction and a preparation method thereof, and belongs to the technical field of building materials. The method comprises the following steps: S1, uniformly mixing glass powder, sulphoaluminate cement, metakaolin and zirconium oxide to obtain mixed powder; s2, uniformly mixing a silane coupling agent, a carboxylic acid polymer and water to obtain a mixed solution, and then mixing and uniformly stirring the mixed powder and the mixed solution to obtain modified slurry; s3, soaking glass coarse aggregate in the modified slurry obtained in the step S2, taking out the glass coarse aggregate after fully wrapping the glass coarse aggregate, and standing and airing the glass coarse aggregate to obtain the glass aggregate for inhibiting the alkali-aggregate reaction. The method provided by the invention can isolate alkaline substances and reduce alkalinity at the same time, thereby effectively inhibiting the occurrence of alkali-aggregate reaction.
本发明公开一种抑制碱‑骨料反应的玻璃骨料及其制备方法，属于建筑材料技术领域。所述方法包括以下步骤：S1.将玻璃粉、硫铝酸盐水泥、偏高岭土和氧化锆混合均匀后得到混合粉料；S2.将硅烷偶联剂、羧酸聚合物和水混合均匀，得到混合液，然后将混合粉料与混合液进行混合并搅拌均匀后，得到改性浆体；S3.将玻璃粗骨料浸泡在步骤S2得到的改性浆体中，充分包裹后取出，静置晾干，即得到所述抑制碱‑骨料反应的玻璃骨料。本发明的方法可以同时隔离碱性物质和降低碱度，进而有效抑制了碱‑骨料反应的发生。
