Building reinforced high-ductility concrete as well as preparation method and construction method thereof
The invention discloses building reinforced high-ductility concrete as well as a preparation method and a construction method thereof. The building reinforced high-ductility concrete is prepared fromthe following raw materials in parts by mass: 1 part of a cementing material, 0.25 to 0.45 part of quartz sand, 0.01 to 0.02 part of synthetic fibers, 0.001 to 0.02 part of xanthan gum, 0.0003 to 0.0008 part of a water reducing agent and 0.25 to 0.35 part of water. The building reinforced high-ductility concrete has excellent toughness and has a good inhibition effect on crack development, xanthangum is doped to improve the cohesive force of the high-ductility concrete, and the surface cohesiveness of the high-ductility concrete and an existing component is improved, so that a surface layer of the building reinforced high-ductility concrete and the component form a whole, and the existing structure has the performance of ductile failure resistance. When a pressing and plastering process is adopted for reinforcing construction, the construction process is simple, and the problem that most reinforcing construction methods are prone to damaging existing structures in the reinforcing process can be effectively solved.
本发明公开了一种建筑加固高延性混凝土及其制备和施工方法，其原料按质量份计算包括：胶凝材料1份，石英砂0.25～0.45份，合成纤维0.01～0.02份，黄原胶0.001～0.02份，减水剂0.0003～0.0008份，水0.25～0.35份。本发明的建筑加固高延性混凝土具有优异的韧性、对裂缝的开展有良好的抑制作用，掺入黄原胶提高其粘聚力，提高了高延性混凝土与既有构件表面粘结性，使得建筑加固高延性混凝土面层与构件成为整体，也使既有结构具有抗延性破坏的性能。采用压抹工艺进行加固施工时，不仅施工工艺简单，而且可以有效的解决大多数加固施工方法在加固过程中易对既有结构造成损伤的难题。
