Abstract

The invention discloses an FRP steel tube recycled concrete short column which comprises FRP layers, a seamless steel pipe, natural pebbles or gravels, recycled concrete, PC ordinary Portland cement, coarse sand and water. The ratio of the PC ordinary Portland cement tothe coarse sand to the water is 500 to 479 to 190. The contents of the natural pebbles or gravels and the recycled concrete content are 1231 and 0 or 923.25 and 307.75 or 615.5 and 615.5 or 307.75 and 923.25 respectively. The concrete is arranged in the steel pipe. One to three FRP layers wrap the steel pipe. Waste concrete is directly utilized and simply processed and is used for coarse aggregate of the concrete according to a certain replacement rate. Therefore, the environmental pressure can be reduced, and the waste concrete can be also turned into wealth to save the costs.

Description

technical field [0001] The invention relates to FRP steel pipe recycled concrete, in particular to a FRP steel pipe recycled concrete short column. Background technique [0002] At present, there is no new type of component such as FRP steel tube recycled concrete component, and similar products are simply a combination of FRP and concrete without combining steel tubes. Or FRP and CFST, no recycled concrete involved. Contents of the invention [0003] Aiming at the above problems, the present invention provides a FRP steel pipe recycled concrete short column. [0004] The technical scheme adopted in the present invention is: a FRP steel pipe recycled concrete short column, including FRP layer, seamless steel pipe, natural pebbles or crushed stones, recycled concrete, PC ordinary Portland cement, coarse sand, water; wherein PC The ratio of ordinary Portland cement, coarse sand, and water is 500:479:190; the content of natural pebbles or crushed stones, and recycled concre...
