UHPC (Ultra High Performance Concrete) material for reinforcing clear water whole rubble wall body and reinforcing method of UHPC material
The invention discloses a clear water whole rubble wall reinforcing UHPC material and a reinforcing method thereof, and relates to the technical field of wall reinforcing, the UHPC material comprises Portland cement, silica fume, limestone powder, quartz sand, iron ore tailing particles, pumice particles, a polycarboxylic acid water reducer, water, toner and modified basalt fiber. The reinforcing mode that novel UHPC (ultra-high performance concrete) is used for filling horizontal and vertical grooves in the outer side of the whole rubble wall body and reinforcing caulking joints in the inner side is combined is adopted, meanwhile, in order to enhance tying of the grooves in the outer surface and the caulking joints in the inner surface, tie bars are arranged, the shear resistance of mortar joints of the whole rubble wall body and the stability of the wall body are greatly improved, and the whole rubble wall body has the advantages of being simple in structure and convenient to use. And the anti-seismic property and durability are remarkably improved, and the method is convenient to construct and can be widely applied to anti-seismic reinforcement of the whole rubble wall. The problem that in the prior art, shear resistance and flexural capacity of a masonry wall are insufficient is solved.
本发明公开了一种清水整毛石墙体加固UHPC材料及其加固方法，本发明涉及墙体加固技术领域，该UHPC材料包括：硅酸盐水泥、硅灰、石灰石粉、石英砂、铁矿石尾矿颗粒、浮石颗粒、聚羧酸系减水剂、水、色粉和改性玄武岩纤维。发明采用新型UHPC(超高性能混凝土)对整毛石墙体外侧水平与竖向开槽进行填充和内侧嵌缝加固相结合的加固方式，同时为增强外表面开槽与内表面嵌缝的拉结，设置了对拉结筋，极大地增加整毛石墙体灰缝的抗剪性能及墙体稳定性，显著提高抗震性能和耐久性，且施工方便，可广泛应用于整毛石墙体抗震加固。本发明解决了现有技术中砌体墙的抗剪和抗弯承载力不足的问题。
