HB7絮凝剂改性富水灌浆材料特性研究
Study on properties of water-rich grouting materials modified by HB7 flocculant
摘要
Abstract
Ordinary cement-based grouting materials have issues such as poor anti-dispersibility and low under-water bond strength in water-rich construction environments.To improve the applicability of cement-based grouting materials in water-rich conditions,HB7 flocculant was used for modification.It was found that HB7 flocculant can effectively enhance the anti-water dispersion performance and underwater bond strength of grou-ting materials.As the HB7 flocculant dosage increased from 1.5%to 3.5%,the anti-dispersibility of HB7-modified grouting materials improved,while the underwater bond strength first increased and then decreased.Compared with the water-rich grouting material modified with 1.5%HB7 flocculant,the 2.5%dosage im-proved anti-dispersibility by 69%and 28-day underwater bond strength by 38%.关键词
