化学预应力混凝土在混凝土内部建立1MPa左右化学预应力,抑制裂缝形成,工程结构混凝土无裂缝,从而确保地下工程抗裂防渗。本文介绍了化学预应力混凝土在滨州学苑花园地下车库工程中的应用情况。通过缩减后浇带设置,降低施工难度,优选HCSA膨胀剂,以强度和限制膨胀率为指标,优化化学预应力混凝土配合比,控制新旧混凝土浇筑时间,加强混凝土振捣、养护及后期成品保护工作,确保了化学预应力混凝土的防水效果。 Chemical prestressed concrete in the concrete to establish about 1MPa chemical prestress, inhibit the formation of cracks, concrete structure without cracks, so as to ensure the anti-seepage of underground works. This paper introduces the application of chemical prestressed concrete in the underground garage of Binzhou Xueyuan Garden. By reducing the post-pouring zone set to reduce the construction difficulty, HCSA expansive agent is preferred, with the strength and limited expansion rate as an indicator, optimize the chemical prestressed concrete mix, control the pouring time of new and old concrete, strengthen concrete vibration, conservation and post-product protection work , To ensure that the chemical prestressed concrete waterproofing effect.
