Embodiment Construction
[0020] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.
[0021] Such as figure 1 As shown, the specific implementation method of the present invention is: construct a kind of hollow concrete member, comprise concrete aggregate, cement, water, mix concrete aggregate, cement, water according to a certain proportion to form concrete 2, also include containing described concrete The columnar base 1, the concrete 2 is poured into the columnar base 1 to form a columnar hollow 3 attached to the inner wall of the columnar base 1, after the concrete 2 is formed in the columnar base 1, the concrete 2 After reacting with carbon dioxide, a hollow concrete member is formed. In the present invention, after the concrete 2 is formed in the columnar matrix 1, the concrete 2 is reacted with carbon dioxide to form a hollow concrete member. Since concrete 2 contains a large amount of calcium hydroxide (chemical formula i...

The invention relates to a hollow concrete member, which comprises a concrete aggregate, cement and water. The concrete aggregate, the cement and the water are stirred and mixed in a certain proportion to form concrete. The hollow concrete member also comprises a columnar substrate which accommodates the concrete. The concrete is poured into the columnar substrate to form a columnar hollow which is adhered to an inner wall of the columnar substrate; and after the concrete is shaped in the columnar substrate, the concrete is reacted with carbon dioxide to form the hollow concrete member. In the invention, the concrete is reacted with the carbon dioxide to form the hollow concrete member; the carbon dioxide is reacted with a hydrated product (calcium hydroxide) of the cement to form calcium carbonate; and the calcium carbonate can improve a contact interface of the concrete aggregate and cement paste, improve the strength of the concrete, and reduce holes of the concrete, so that durability of the concrete is improved.
Description
technical field [0001] The invention relates to a concrete component and a preparation method thereof, in particular to a hollow concrete component made of concrete aggregate and a preparation method thereof. Background technique [0002] With the development of society, there are more and more buildings and construction projects of all kinds, and concrete components are widely used in construction projects: such as metallurgical industry, electric power industry, shipbuilding industry, machinery manufacturing industry and industrial or civil buildings, etc., can be used in Boiler components and power transmission and transformation frames, columns in assembly workshops, single-story or multi-story industrial plants, high-rise or super-high-rise civil buildings, highways and urban arch bridges, etc., are also used in pole tower structures, columns and columns of industrial plants and civil buildings in the foundation pile. In construction engineering, the higher the strengt...
