Description

Structure reinforcement method using liquid ceramics {omitted}

The present invention relates to a method for performing waterproofing, anticorrosive work for concrete protection coating using carbon fiber and liquid ceramic having strong tensile strength in various reinforced concrete structures of water purification plant system and sewage treatment plant series.

In general, the biggest cause of the defects in reinforced concrete structures in waterproofing and anticorrosive construction is the poor concrete ground treatment (removal of tartans, poor pinhole expansion) and the construction materials used are organic materials, and the pH is less than 6 The product lacks Mars, and the more decisive factor is that the waterproof, anticorrosive structure cracks due to the strong contraction and expansion of the reinforcement and concrete, and the self-organization of the waterproof structure penetrates deeply into the reinforced concrete structure. By promoting the deterioration of the reinforced concrete structure due to neutralization.

Cement-based liquid waterproofing, liquid-permeable waterproofing, mother-permeable waterproofing, and organic solvent-based coating waterproofing are insufficient to remove the original defects of defects due to the lack of perfect base treatment (base treatment) during construction. In the cement-based mortar waterproofing system, there is a natural lack of a crack prevention device due to the self-organization of the waterproofing finished material and shrinkage expansion of concrete.

When mixed with cement, the liquid waterproofing of calcium chloride and sodium silicate due to the simplistic reaction of increasing exothermic temperature, despite the thick protective mortar layer, erosion of concrete spheres and internal reinforcement due to chemical reaction (oxidation) of applied materials. In addition, the thick protective mortar layer promotes the deterioration (fragmentation) and the fall of concrete due to the reaction of the infiltrate water due to the lack of strong crack protection.

Liquid permeable waterproofing developed as a method of improvement also occurs in cracking due to external factors and self-curing process due to lack of crack preventing device, despite its excellent function as waterproofing agent such as impermeability, moisture resistance, water resistance, etc. It is impossible to prepare by the heat and so on.

Maternal penetrability, developed due to the limitations of mortar waterproofing, is also a thin film (T = 1 ~ 2M / M), which penetrates deep into concrete deeply due to hydration which continuously penetrates by external water pressure. It has excellent excellence as a material for strong pressure against hydraulic pressure, but there is a limit in preventing cracking of concrete spheres and cracking due to impact of waterproof coating layer due to external factors due to crack prevention and inability to combine construction.

Due to these factors, it is impossible to prevent cracking of structures made of waterproof mortar without applying the carbon fiber member due to the strong tensile force.

In other concrete structures, such as water purification plants and sewage treatment plants, acid rain from carbon dioxide (CO2), nitrous oxide (NOx), and oxygen sulfur in the air penetrates into alkaline concrete, resulting in deterioration of concrete, cracking, and chlorine in water. As an ingredient, an alkali silica gel is formed by reaction with alkali of concrete.

As the alkali silica absorbs water, the concrete expands and deteriorates and small debris is formed, and the water penetrates due to cracks, causing internal reinforcing bars. Oxidation corrosion is accelerated and concrete structures are destroyed.

In addition, the concrete structure of the sewage treatment plant series stores the corrosive sewage or sewage sludge, which contains a large amount of organic matter including sulfates and sulfur, and thus accelerates oxidation corrosion.

Moisture promotes deterioration of concrete compounds. Since deterioration, cracking, and dropping of concrete are directly related to water penetrating from the outside, it is necessary to block the infiltrating water at the source, and to have water resistance to always exclude water ingress with low absorption rate, and similar coefficient of thermal expansion to concrete. The breakdown and peeling of the waterproof layer against the furnace temperature difference should not occur, and the moisture remaining in the concrete should be completely released during the long curing period.

By applying homogeneous materials that have affinity with concrete, concrete materials have a low saturation temperature to maintain a strong adhesive force that is not damaged by sound, vibration, or impact even in low temperature water, and deterioration crack leakage corrosion due to neutralization as described above. Long-term measures to permanently maintain the concrete structure by blocking the occurrence of defects should be taken.
