Description of the Invention: [Technical Field of the Invention] The present invention relates to a slurry for concrete, and more particularly to an alkali-activated slurry for concrete. [Prior Art] In recent years, due to the rapid development of industry and urban areas, a large amount of carbon monoxide is emitted. 'The large amount of carbon dioxide emitted is accumulated in the atmosphere because it cannot be absorbed by the ocean and forests', and the more carbon dioxide is accumulated in the atmosphere, the temperature increases. The more the temperature increases, the more carbon dioxide remains in the atmosphere. This creates a vicious circle, which causes the pollution of the global environment and the greenhouse effect to become more serious. Among them, the largest producer of carbon dioxide emissions, in addition to steelmaking, In addition to coal-fired power generation, the most important thing is the cement industry. Cement is an important industry in Taiwan's construction and economic development. However, traditional cement slurry needs to be prepared after high-temperature firing of calcium carbonate. In the production process, not only a large amount of energy is consumed, but also a large amount of carbon dioxide is generated; It is estimated that the production of 1 public cement will emit 880 kilograms of carbon dioxide. 'The right amount of cement produced in Taiwan’s mother year is about 2 million. The annual amount of carbon dioxide produced by Taiwan’s cement production is as high as 16 million. After the 'Kyoto Agreement' came into effect in early 2005, the issue of greenhouse gas reduction was officially entered. It entered a new stage of international legal binding. Although China is not a signatory to the protocol, China’s total greenhouse gas emissions are in the world. Ranked 22nd, 'accounting for nearly 1% of the world, so how to actively reduce greenhouse gas emissions in various industries is one of the most important environmental issues. Therefore, how to develop new materials that can replace traditional cement slurry and not consume a lot of energy in the process of production 201210979, and will not produce carbon dioxide, while developing industrial technology, also try to reduce the development of technology due to the earth. The pollution and damage caused by the environment is an important issue that continues to be developed by the technical field.

Acid, alkali and salt, etc., only the base has a direct destructive effect on the network structure of the cerium salt material; the stronger the testability and the higher the temperature, the more likely the chain cleavage of the citrate network structure is caused. In general, the activity of crystalline materials is low, while amorphous materials are highly active due to incomplete structure. In order to effectively chemically activate crystalline or amorphous citrates, the Si-0-Si and/or Si-〇-Al network structure must be destroyed by a highly alkaline solution to deagglomerate the network surface aggregates.

Therefore, the present invention controls alkali activation by using an alkali metal hydroxide, an alkali metal niobate and/or a tannic acid gel. In addition to the basicity of the liquid, and further adjusting the aluminum content of the alkali activation liquid by alkali metal aluminate or aluminum powder, the required Al〇4 monomer is supplemented according to the actual situation, so that not only the high alkaline solution can be compensated for A disadvantage of insufficient amount of Aio4 monomer dissolved on the surface of the powder, and the inorganic powder of the field is a compound containing no aluminum, or a compound having a very low aluminum content, such as glass, It can be used normally, not only can the cement material structure be more complete and enhanced by the addition of aluminum, and it is not limited to the kind of materials used, but has a wider choice of materials. It should be noted that when the test property (M2〇) is too high, a sodium bicarbonate crystal substance formed by reacting an alkali metal with water vapor and carbon dioxide in the air is formed on the surface of the finished product prepared from the slurry ( Commonly known as Baihua), and because of the high testability, it will destroy the bond formed and cause the strength to decrease; and when the alkali is insufficient, the reactivity is too low, and the strength of the finished product made from the slurry is insufficient. Preferably, the molar ratio of the cerium oxide to the alkali metal oxide (Si02/M20) of the alkali activating solution is between 0.375 and 0.5, and the molar ratio (SiCMAhO3) of cerium oxide to lanthanum trioxide is between 20 and Between 80; more preferably, the molar ratio of the cerium oxide to the alkali metal oxide (Si〇2/M2〇) of the activation liquid is between 0.375 and 0.5' and the oxidization of the oxidized stone and the oxidized The molar ratio (Si02/Al203) is between 40-60. In addition, it is to be explained that when the viscosity of the alkali-activated slurry is too low, the fluidity is too high, and it is easy to cause a vertical flow phenomenon due to its own weight during use. When the viscosity is too high, it is easy to cause activation cracking. The body mixing is not easy, and 201210979 makes the alkali activation reaction incomplete. Therefore, preferably, the weight ratio of the alkali activation liquid to the inorganic powder (hereinafter referred to as the liquid/solid ratio) is between 1 and 0.5, more preferably The liquid/solid ratio of the test activation liquid to the inorganic powder is between i and 〇67, and the viscosity of the alkali-activated slurry is 10,000 to 60,000 mpas. When the alkali-activated slurry is further mixed with coarse and fine aggregates to form mortar or concrete, it can be used as a construction material, which can not only partially or completely replace the traditional cement, but also can be crystalline or non-organic due to the inorganic materials used. Crystalline raw materials or waste, therefore, it is not necessary to use traditional cement, it must first be fired by high-temperature carbon citrate to produce cement, which has the function of energy saving and carbon reduction, due to the material type of the coarse and fine aggregates. The selection is well known to those skilled in the art, and is not the focus of this technology and therefore will not be further described. The preferred embodiment of the present invention will be more clearly understood in conjunction with the following 16 specific examples and the description of the four comparative examples. Inorganic powder raw material 1. Water quenching furnace stone powder: The water quenching slag produced by the steelmaking plant in the blast furnace is uniformly ground. 2. Coal-fired fly ash: The power plant burns coal to generate electricity, and collects very fine particles of unburnt substances through the flue. 3. Waste glass powder: The recovered waste glass is ground into powder. &lt;Specific Example 1&gt; The specific example 1 of the alkali-activated slurry of the present invention is that the water quenching furnace powder is first weighed as an inorganic powder raw material, and sodium hydroxide, sodium citrate and sodium aluminate are added to water to be uniformly mixed. After obtaining an alkali activation solution, and controlling the molar ratio of S1〇2/Na2〇 of the alkali activation solution to 〇·5, the molar ratio of SiO 2 /Al 203 is 201210979 20 , and the liquid of the inorganic powder and the alkali activation liquid/ The solid ratio is 10, and then the alkali activation liquid is added to the above-mentioned inorganic powder and stirred to form a uniform slurry of the alkali activation liquid and the inorganic powder, thereby obtaining the alkali-activated slurry of the present invention.
