Description of the Invention: [Technical Field to Be Invented by the Invention] 5 The present invention relates to a doping effect and can be used for concrete work [Prior Art] A special type of mineral doping with energy-saving and carbon-reducing energy composite type. - Generally speaking, there are many kinds of concrete minerals used in the past. Some have hydration reactions such as hearth powder, some have sputum reaction such as fly ash, Shishi ash, some have only micro-cohesive properties such as converter stone powder, volcanic ash is more complete. There is no cementation and only has a filling effect to increase the density of concrete.: 10 The above-mentioned additives are referred to as concrete auxiliaries. However, the additives have their own advantages and disadvantages. If one of them is used alone or used in excess, It often causes another negative effect on the concrete, which in turn reduces the quality of the concrete and the purpose of using the original admixture. For a long time, with the increasing awareness of environmental protection and the limited amount of cement 15 mining in Taiwan, some operators have developed a concrete 1 in order to reduce the amount of cement used in conventional concrete, as shown in Figure 1, which is mainly composed of water. 11. The cement 12, the sand stone 14 and the concrete additive 13 are mixed; wherein the concrete additive 13 is composed of converter stone powder and gypsum material produced by the steel making process, or the concrete auxiliary 13 system can be fly 10 ash or whetstone powder ' or a two-in-one product (not shown) formed by the fly ash or ston furnace powder, the concrete auxiliary 13 containing converter stone powder and gypsum material is taken as an example here; When the concrete additive 13 is used in combination with the cement 12, the part of the cement 12 can be replaced by adding water 11 to form the concrete 1. 201103881 However, after actual use, it is found that the coagulation is in the manufacturing process, and the manufacturer usually pre-mixes the cement 12 with the concrete additive 13 by the premixer in a specified ratio (for example, 50% cement 12 and 5〇% of concrete additive 13) 'However, since the cost of the concrete additive 13 is lower than that of the 5 cement 12, the addition of the concrete additive 13 is greatly increased in order to obtain a higher spread therefrom. The proportion, so that more cement 12 parts are replaced to reduce the amount of addition (such as 35% of cement 12 with it, soil aids " 3) 'to reduce production costs; this is due to human factors to reduce the cement 12-scale behavior, it is easy to add the water after the addition of the water, because the concrete additive 13 contains a variety of mineral impurities, and as the water 11 floats on the surface of the concrete i, thereby generating floating powder, floating black or Caused by the low early strength of the concrete i and other negative effects, especially when the converter powder or fly ash is mixed with the cement 12 in an excessively high proportion, it is easy to feed (4) the effect and volume stability of the county Strength safety characteristics Responding to the quality of the soil (4), the concrete formed can not be transported into the expected effect, so the scope of use of the concrete additive 13 is more limited, and it is limited to the actual use. Cannot be effectively and widely applied. SUMMARY OF THE INVENTION The object of the present invention is to provide a multi-functional composite mineral admixture for concrete, which can solve the problem of arbitrarily changing the ratio of cement to concrete auxiliaries, or use the early concrete in the 祛 祛 00 The quality of the concrete formed by the auxiliaries and the shadow plastics, the gentry 1 Bego barrier "effectively improve the quality and efficiency of use to achieve energy saving and carbon reduction. 20 201103881 The invention relates to a multifunctional composite mineral admixture for concrete, which is mainly prepared by mixing mineral fillers such as hearth powder and converter stone powder according to a specific ratio, so as to make the composite type admixture obtained by waterfall mixing.
