Problems solved by technology

[0004] In order to comply with the concept of environmental protection and sustainable development, most of the concrete products are currently produced by recycling recycled aggregates. However, due to the low processability, the formed concrete products have low density and insufficient strength, which has a great impact on the application range. limits

Abstract

The invention discloses a high-density concrete product molding method, which belongs to the technical field of concrete product production. The invention can partially replace recycled aggregate by introducing compacting balls, which itself has good strength and can be used in mixing During the pouring process, the heat of hydration phenomenon is used to trigger its degassing action, and the wax bag inside the degassing tank on the surface of the dense ball is melted, and the connection is established between the dissolved air bag and the suction water bag, and the soluble gas in the dissolved gas bag quickly Dissolved in water, at the same time the dissolved air bag begins to shrink rapidly, resulting in a decrease in the air pressure in the degassing tank. Air is introduced in the mixture through the air-introduced fiber tube, and the residual air is guided into the degassing tank to balance the air pressure. After the soluble gas is completely dissolved, the preset cooling layer will start to contact and dissolve, and absorb a large amount of heat, forcing the melted wax bag to solidify in the designated area to achieve sealing, avoid secondary leakage of air, and achieve effective removal of the mixture. Air, thereby improving the compactness of concrete products after molding.

Description

technical field [0001] The invention relates to the technical field of concrete product production, and more specifically, relates to a high-density concrete product forming method. Background technique [0002] Concrete products are products made of concrete (including mortar) as the basic material. They are generally prefabricated in factories and then transported to the construction site for laying or installation. For large or heavy products, due to the inconvenience of transportation, they can also be prefabricated on site. There are reinforced and unreinforced ones, such as concrete pipes, reinforced concrete poles, reinforced concrete piles, reinforced concrete sleepers, prestressed reinforced concrete bridges, reinforced concrete mine supports, etc. Widely used in construction, transportation, water conservancy, agriculture, electric power and mining and other departments. [0003] It mainly includes concrete masonry material modules (3 categories and 41 kinds of pr...
