[Field of the Invention] The present invention relates to the eradication method of building monuments, cement sand concrete overlay members, and more particularly to an alkali-sUica complex eradication agent formulation and eradication law. [Background of the invention] Lack of conventional technology In recent years, pollutants have been laid out on the monuments of buildings, which destroys the beauty and is free of cleaning agents, hydrochloric acid, or waterproofing. It is not necessary to continuously suppress the pollutants. New monuments and sand aggregates may not be effective. π immune If this is because the general public does not understand the true countermeasures for pollution, and the use confirms that the above-mentioned phenomenon was thoroughly explored by the inventor of the case, and research and development and other cases, the product dyes that reacted with the active silicon material originated from the sand slurry under the floor tiles The products produced by the alkaline reaction melt down through the seam and other paths. The capillary diffusion cracks may come from the invasion of pollutants. This is a natural defect of the floor tile itself. In addition, water separation and sedimentation and adhesion of brick bottoms were generated. Not long after the completion of the monument, a monument or a seam can be found to eradicate it. The general public responded to the use of various inhibitors to treat the affected areas, and they even emerged, even after being cleared and re-laid. ○ The real cause was that they could not come up with an effective treatment method. After 84 years of appraisal and treatment in China, it was found that the pollutants of this floor tile are alkaline and have the characteristics of water absorption, swelling and dispersion. Some bricks, glaze components, etc. are penetrated by cement strong mortar, or pinholes and cracks in the glaze. This stele glazed pinhole and the interaction between the turtle and the swelling, or the current paving method of the floor tile caused a large amount of local high alkalinity, which accelerated the pollution.

Page 5 495493 V. Description of the invention (2) The newly discovered problems are caused by the good sand material bred from the geological area of Taiwan. This cancer is generally caused by the rough crevices of the inscription method. And high-quality inspection on the sticking interface at the bottom of the tablet and the tombstone] :: Partly caused by the phenomenon of pollutant generation. In contrast to traditional concrete problems, only coarse aggregates of sand and gravel and strong alkali generated by cement produce structures that differ from heavy cracks. This case focuses on the eradication of this pollutant. The traditional mixed soil problem focuses on the prevention of mechanical damage. In addition to the participation of traditional natural fine sand aggregates in this case, this case also involves multiple new composite compounds such as artificial ceramic materials and construction methods. problem. Therefore, the nature of the issues discussed by the two is different, and the basic materials involved are also different. The origin of the pollutants and the mechanism of the monument pollution phenomenon are caused by the mortar and the artificial minerals of the brick bottom laying mortar, which are mixed with the cement and the alkali (partial, partial or all) in the mortar. The chemical reaction produces colloidal products, which are separated and precipitated in the slurry by the current artificial paving method due to simplification and inaccuracies, and the remaining small atomic volume of metal detection ions remaining after the slurry solidifies. After the solution is dissolved (absorbed) into the colloidal product, a complex alkali-silica complex ion (alkali-si lica complex) contaminates the colloid. This colloid is hydrophilic, and can swell and swell due to inhalation of too many water molecules and surrounding compatible ions, and the polluting colloid itself is strongly alkaline, so that it continues to erode, dissolve, swell, and circulate. Function, and, in the "Lei Feng Feng Yuan Ⅱ" porcelain monument cement mortar environment, continuously alternately react, pool, channel, sub-capillary, diffusion and penetration, wet and dry alternate in the atmosphere, etc. 3) The gaps specific to the pings (hitch, cracks in glaze, pinholes) are gushing out. Demand in the industry The problem of pollutants in monuments has for many years caused continual problems and disputes in the construction industry, housing quality assurance, and the tile industry. The industry needs a simple, effective and stable tombstone pollutant eradication agent to combat countless potential and persistent pollution problems. [Prior Art] In World Patent No. 9 3 1 2 0 5 2, the current transfer in the cathodic corrosion method, electrochemical desalination, or alkali recovery method is applied by traditional steel bar corrosion protection method L i + (inhibition Agent) to potentially reactive stones to prevent alkali-stone aggregate damage to concrete. The patent also proposes to use a mixture of repairing cement materials with Li + compounds to directly repair the affected part of the alkali silica aggregate, and gradually repair the affected part by the difference in concentration. This method is mainly suitable for outdoor buildings and focuses on prevention. This method is to mix concrete when constructing concrete materials, or to cover the surface with Li repairing cement as anode material. Therefore, the main purpose of treatment is to prevent the formation of colloids on the surface of reactive aggregates, which can be precipitated in combination with Li. [Objective of the Invention] The main object of the present invention is to provide an alkali-silicon complex eradication agent formulation 'for eradicating pollutants formed by the reaction between strong alkali and vitreous. Another object of the present invention is to provide a method for eradicating an alkali-silicon complex, which is used to treat and decompose the formed and cured alkali-silicon reactive colloid, and 495493
