Abstract
The invention relates to a carbon-supported chloride cement brick. The carbon-supported chloride cement brick is characterized in that the carbon-supported chloride cement brick comprises 40-60wt% of blast furnace slag, 20-30wt% of gangue, 5-10wt% of lime and 4-8wt% of calcium chloride. A making method of the carbon-supported chloride cement brick comprises the following steps: burdening in proportion, adding water to calcium chloride for dissolving, mixing above ingredients, adding water to the mixed ingredients, stirring to obtain a mixture having a water content of 20-30%, stirring the mixture, casting, molding, and air-drying. In the making method, a maintenance pressure is 0.05-0.15Mpa, a maintenance temperature is 10-50DEG C, and a maintenance time is 8-12h. The carbon-supported chloride cement brick has the advantages of absorption of carbon dioxide in the molding process, high strength, short production period, less apparatus investment, wide sources of raw materials, low price, low cost and energy saving.
Description
Technical field
The present invention relates to a kind of material of construction and preparation method thereof, particularly negative carbon cement brick of a kind of villaumite and preparation method thereof.
Background technology
At present, though coal gangue can be used with cement mixing, addition content is generally less, otherwise the requirement that product strength cannot be up to state standards.On domestic market, being known as the building materials that utilize coal gangue to produce, is mostly to mix use with cement and other and intensity is not very high.And belong in the world technological precedence by the new building material technique that concrete making technology also uses the intensity of coal gangue (not adding people's cement) production to meet technological standard completely.The weak point of above-mentioned autoclaved fly ash hollow brick is: the addition content of flyash is low, and lime, cement price are higher, cause the cost of brick high, also can think airborne release carbonic acid gas in manufacturing processed simultaneously.
Summary of the invention
Little in order to solve existing gangue cement coal gangue addition content amount, there is in process of production carbon emission, the shortcoming that brick volume density is high, the invention provides the negative carbon cement brick of a kind of porous.
The technical solution adopted for the present invention to solve the technical problems is: described a kind of villaumite is born carbon cement brick, blast furnace slag, coal gangue, lime, calcium chloride, consist of, the following row weight percent of its raw material is made: blast furnace slag 40%-60%, coal gangue 20%-30%, lime 5%-10%, calcium chloride 4%-8%.
The preferred weight percent of above-mentioned blast furnace slag, coal gangue, lime, calcium chloride is:
Blast furnace slag 55%
Coal gangue 30%
Lime 8%
Calcium chloride 7%.
The preparation method of above-mentioned negative carbon cement brick, batching first in proportion, calcium chloride is dissolved in water, by batching mix and add water stir the water ratio compound that is 20-30%, again by compound stirring, moulding, moulding, air-dry; In above-mentioned preparation method, maintenance pressure is 0.05-0.15Mpa, and curing temperature is 10-50 ℃, and curing time is 8-12h.
The invention has the beneficial effects as follows: absorbing carbon dioxide in moulding process, intensity are high, with short production cycle, and few, the original source of equipment investment is wide and cheap, cost is low, save energy.
Embodiment
Below in conjunction with embodiment, the present invention is further described.
Embodiment 1:
