山西省建委主持的 GXF-1型混凝土膨胀剂应用推广会于1996年5月8日在太原市山西省建筑科学研究院召开。来自省内设计、施工、科研、管理、信息等18个单位的44名同志出席了会议。GXF-1型混凝土膨胀剂是由山西省建筑科学研究院、灵石常青水泥厂膨胀剂联营厂研制开发成功的,经山西省建筑工程质量监督检验站抽检和多项工程中使用,效果良好。1994年12月通过省级成果技术鉴定,达到国内同类研究先进水平。95年5月获山西省建设厅颁发的新产品推广许可证。该膨张剂具有优良的抗裂防水性能,掺入混凝土中后,由于膨胀作用,填充切断毛细孔缝,孔隙率减少,从而提高了混凝土的致密性,并可产生0.2-0.7MPa 的自应力,
The application and promotion of GXF-1 concrete expansive agent presided over by the Shanxi Provincial Construction Committee was held on May 8, 1996 in the Shanxi Academy of Building Science, Taiyuan. 44 comrades from 18 units including design, construction, research, management, and information in the province attended the meeting. GXF-1 concrete expansion agent was successfully developed by the Shanxi Provincial Academy of Building Research and Lingshi Evergreen Cement Plant expansion agent joint venture. It has been used in sampling inspections and construction projects of the Shanxi Province Construction Engineering Quality Supervision and Inspection Station. In December 1994, it passed the provincial-level technical appraisal to reach the advanced level of domestic similar research. In May 1995, it was granted a new product promotion permit by the Department of Construction of Shanxi Province. The expansive agent has excellent crack resistance and waterproof properties. After being incorporated into the concrete, due to expansion, the pores are filled and cut to reduce the porosity, thereby increasing the compactness of the concrete and producing a self stress of 0.2-0.7 MPa. ,
