Forming process of anti-corrosion concrete prefabricated square pile

Abstract

The invention discloses an anti-corrosion concrete precast square pile forming technology, and belongs to the field of anti-corrosion concrete pile forming preparation technology. According to the anti-corrosion concrete precast square pile forming technology, additives such as fly ash and mineral powder can be more uniformly mixed in slurry in the slurry mixing process, a large amount of bubblesare injected into the concrete slurry in the water injection slurrying process, a large amount of heat and energy can be generated when the bubbles make contact with foreign matter to explode, cement,gravel and fine powder in the slurry are mixed more uniformly, so that the compactness of concrete is greatly improved, the concentration of sulfate ions which can invaded into the concrete can be reduced, the pore diameter of capillary pores is thinned, the precipitation speed of calcium hydroxide from a cement stone is inhibited, the generation of gypsum and ettringite crystals is delayed, theeffect of inhibiting the expansion damage of the concrete is achieved, and the speed of sulphate attacking and damaging on the concrete is delayed.

Description

technical field [0001] The invention relates to the field of anti-corrosion concrete pile forming technology field, in particular to a anti-corrosion concrete prefabricated square pile forming process. Background technique [0002] Concrete is concrete, which refers to the general designation of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] In the process of actual production, technicians found that although concrete materials have relatively good compressive properties, strength and corrosion resistance in a neutral environment, in a saline-alkali environment, the salt ions rich in saline-alkali soil will di...

Problems solved by technology

[0005] However, in the traditional mixing process of the above means, it is difficult to mix the additive fly ash, mineral powder and cement slurry evenly, which makes the effect of the additive worse.
