HB7-18防裂剂与PVA纤维抗裂材料对面板混凝土性能影响研究
Study on Influence of HB7-18 Anti-Cracking Agent and PVA Fiber Anti-Cracking Materials on Performance of Panel Concrete
摘要
Abstract
In response to the cracking issue of thin-walled slab concrete at the Jinchuan Hydropower Station of Dadu River,HB7-18 anti-cracking agent and PVA fibers were incorporated into the benchmark concrete,respectively.Experimental studies were conducted on the mechanical properties,durability,deformation properties,and crack resistance of the two types of anti-cracking concrete,analyzing the impact of anti-cracking materials on the performance of panel concrete.The test results indicate that compared to the benchmark concrete,both HB7-18 anti-cracking agent and PVA fiber concrete can effectively enhance the anti-cracking performance and overall durability of panel concrete.Given the high demand for early-age anti-cracking performance in panel concrete,PVA fiber is more compatible in ensuring construction quality and long-term stability of the structure.It is recommended to use PVA fiber concrete as the mix design for the panel concrete construction of the Jinchuan Hydropower Station.关键词
