Concrete impermeable sealant

Abstract

The invention relates to oil, grease or wax for post treatment of concrete, in particular to a concrete impermeable sealant. The concrete impermeable sealant is formed by stirring 62 to 67 mass percent of lithium-based grease, 31 to 36 mass percent of admixture and the balance of engine oil uniformly, wherein the lithium-based grease is formed by mixing and thickening 9 to 13 mass percent of 1,2-hydroxy lithium stearate, 0.5 mass percent of diphenylamine, 0.5 mass percent of petroleum barium sulfonate and the balance of mineral oil; and the admixture is selected from fly ash, coal gangue powder and cement powder, and the granule diameter of the powder is less than 0.9 millimeter. The concrete impermeable sealant is convenient to manufacture and use, is simple in operation, time-saving and labor-saving, has good sealing property, has no harm to the human body, and is environmentally-friendly.

Description

technical field [0001] The invention relates to oil, grease or wax used for post-treatment of concrete, in particular to a concrete anti-seepage sealant. Background technique [0002] After the concrete component is made, it is necessary to test the impermeability of the product. The testing process is usually: first use the same material as the component to make a sample. The sample is in the shape of a cone, and the diameter of the upper bottom surface of the usual specification is 175mm, and the diameter of the lower bottom surface is 185mm. , 150mm in height. After the preparation, the sample is firstly cured for 28 days. After the curing, the anti-seepage agent is applied on the surface of the sample. At present, paraffin and rosin are generally used. When applying, the paraffin and rosin are firstly heated to melt them into Then apply it around the side of the sample, let it cool down after coating, and heat the impermeable mold, so that the mold will expand under the ...

AI Technical Summary

Problems solved by technology

There are two disadvantages in adopting paraffin wax and rosin. One is that paraffin wax and rosin produce pungent taste in the heating process, which affects the operator.

The second is that the sealing is relatively poor. It is difficult to apply paraffin wax evenly on the surface of the test piece, and the thickness varies. Moreover, the paraffin wax becomes brittle after cooling. In the process of loading into the mold, it is easy to apply a large external force. The paraffin wax attached to the surface of the sample falls off or is squeezed and cracked, thus losing the effect of impermeable sealing
