Oxygen steaming-free high-strength concrete anticorrosive pipe pile and production method thereof

Abstract

The invention discloses an oxygen steaming-free high-strength concrete anticorrosive pipe pile and a production method thereof, the oxygen steaming-free high-strength concrete anticorrosive pipe pile comprises the following components: by weight, 165-220 parts of cement; 85-210 parts of mineral powder; 80-225 parts of ultrafine powder; 700-790 parts of sand; 950-1040 parts of stones; 4.13-5.76 parts of a water reducing agent; 7-10 parts of a rust inhibitor and 120-170 parts of water, and with the water-binder ratio of 0.31 to 0.36. According to the production method, a high pressure oxygen steaming process is omitted, a large number of coal and electric power are saved, emissions of smoke and dust are reduced, the production method is green and environmentally friendly, meets the national low carbon production requirements and reduces the environmental burden of enterprises, and mechanical properties and durability of the produced oxygen steaming-free high-strength concrete anticorrosive pipe pile are superior to that of pipe piles in the prior art.

Description

technical field [0001] The invention relates to pipe piles, in particular to an oxygen-free high-strength concrete anticorrosion pipe pile and a production method thereof. Background technique [0002] At present, the mainstream pipe piles in China are C70 and C80 concrete prestressed pipe piles. They use cement and finely ground quartz sand as cementing materials during production. When the concrete strength reaches 40MPA, it is demoulded, and then enters the autoclave for secondary high-pressure steam curing, so that the concrete strength reaches the strength required by the C80 standard. [0003] Since the high-pressure steaming process consumes one-half to two-thirds of all steam consumption in the production process of pipe piles, and the steam after heat exchange becomes condensed water, the pH value of the water is as high as 13; The breeding process requires special equipment such as autoclaves, and the management requirements are higher. Most of the heat energy ge...

Problems solved by technology

Most of the heat energy generated in the above production process is discharged, resulting in a great waste of energy. At the same time, in order to meet the requirements of high-pressure oxygen evaporation, a large amount of coal or electric energy is required, which is likely to cause environmental pollution and energy waste.
