Ground mending agent for concrete

Abstract

The invention relates to the field of building materials, and is intended to provide a ground mending agent for concrete. The ground mending agent for concrete is prepared from the following raw materials: 5 to 15 percent of sodium stannate solution, 3 to 10 percent of silicon dioxide sol, 1 to 8 percent of acrylic acid emulsion, 2 to 5 percent of sodium sulfate solution, 1 to 4 percent of aceticacid solution and 10 to 15 percent of ethanol for preparing a component solution A; 15 to 30 percent of cement, 15 to 45 percent of aggregate, 0 to 2.5 percent of retarder, 0 to 5 percent of anti-toughening agent and 1 to 5 percent of inorganic toner for preparing a component material B; and the balance of distilled water for preparing the component solution A; and the percentages are all percentages by mass, which mean the percentage of each component accounts in the total mass of mending agent. The product disclosed by the invention is a novel water-based ground-mending material integrated with dyeing and mending, the preparation process is simple, the reaction process is easy to control, the reaction conditions are mild, no volatile poisonous gas is produced in reaction, the ground mending agent for concrete does not pollute the environment, moreover, the materials are simple, the cost is low, construction is convenient, and the ground mending agent for concrete is particularly suitable for large-area industrial production and construction.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a ground repair agent for concrete. Background technique [0002] Concrete is the most widely used man-made building material, and is widely used in various structural projects; however, due to the limitations of the concrete material itself and the construction level, many infrastructures, industrial plant floors, etc. have long been damaged, and the surface has potholes, weathering, Dust, sand, and peeling phenomena lead to poor wear resistance and short service life. They can no longer meet the needs of modern production environments and are in urgent need of renovation; the aging and dilapidated ground can no longer meet the current production, work and environmental requirements, and needs to be done in time. Repairing and beautifying treatment; at present, the more popular treatment methods for old ground in domestic and foreign markets: one is to re-grind the ground, and ...

[0002] Concrete is the most widely used man-made building material, and is widely used in various structural projects; however, due to the limitations of the concrete material itself and the construction level, many infrastructures, industrial plant floors, etc. have long been damaged, and the surface has potholes, weathering, Dust, sand, and peeling phenomena lead to poor wear resistance and short service life. They can no longer meet the needs of modern production environments and are in urgent need of renovation; the aging and dilapidated ground can no longer meet the current production, work and environmental requirements, and needs to be done in time. Repairing and beautifying treatment; at present, the more popular treatment methods for old ground in domestic and foreign markets: one is to re-grind the ground, and improve the hardness and gloss of the ground with nano-silica sol (such as CN201010543000.8) as the main component of the seal hardener Amon
