Abstract
The invention provides a method of burying carbon dioxide into concrete and is characterized in that cement, medium sand and gravels are mixed with carbonated water which has a temperature of -1 DEG C to a normal temperature and a pressure of 0.01 to 1 MPa to prepare concrete. Carbon dioxide is pressurized into water to form the carbonated water for subsequent usage. A production process for the carbonated water is mature, and large scale utilization of the carbonated water enables production cost for the carbonated water to be substantially reduced. The concentration of the carbonated water is affected by the temperature and pressure of the carbonated water. According to the invention, the carbonated water is used to replace conventional drinking water in stirring of cement mortar or concrete; carbon dioxide can be buried into constructional cement mortar or concrete, the strength of the cement mortar or concrete is not reduced, so a great amount of the greenhouse gas carbon dioxide can be consumed. The strength of concrete is affected by a plurality of factors like clay content in coarse and fine aggregate of different batches, the degree of mixing uniformity and vibration, and there is a great variety of cement; thus, the invention is not limited to embodiments disclosed in the specification. In all the embodiments in the invention, the total amount of mixed concrete includes loss of concrete in preparation of concrete test blocks.
Description
Technical field
The present invention relates to a kind of method that can consume carbonic acid gas in the atmosphere.
Background technology
Carbonic acid gas is a compound common in the air, is a kind of colorless and odorless gas under the normal temperature, and density is more bigger than air, can be water-soluble, and generate carbonic acid.Solid carbon dioxide is commonly called as dry ice.Carbonic acid gas is considered to cause the main source of Greenhouse effect.Along with Greenhouse effect are on the rise, people are seeking to reduce discharging and handle the method for greenhouse gases (being carbonic acid gas) always, for example: plant tree, carbon tax, the purchase of carbon discharge capacity etc.
Summary of the invention
The purpose of this invention is to provide a kind of method that can consume carbonic acid gas in the atmosphere.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of with the carbonic acid gas concrete method of nuzzling, and it is characterized in that: with cement, medium sand and rubble and Soda Ash Light 99.2min. mixed concrete, wherein; The Soda Ash Light 99.2min. temperature is 0.1 a ℃-normal temperature, and pressure is 0.01-1MPa.
The Soda Ash Light 99.2min. mature production technology, extensive use will reduce its production cost greatly, and Soda Ash Light 99.2min. concentration receives the influence of its temperature and pressure.
The quality proportioning of cement, Soda Ash Light 99.2min., medium sand and rubble is according to the relevant criterion and the conventional ratio of industry of cement in " jgj55-2011 design of common concrete proportioning rules " and " the GB50204-2011 concrete structure engineering construction quality acceptance specification ", water, thick, fine aggregate.
The present invention with Soda Ash Light 99.2min. replace conventional tap water mix cement mortar or concrete can be with carbonic acid gas nuzzle sand-cement slurry for building or concrete; Earlier subsequent use making it to become Soda Ash Light 99.2min. in the pressurized carbon dioxide entry, replace conventional tap water with Soda Ash Light 99.2min. again and mix and stir sand-cement slurry or concrete.Sand-cement slurry or concrete strength are not seen reduction, can consume a large amount of greenhouse gases carbonic acid gas like this.
