Problems solved by technology

[0004] In order to solve the problems that the existing concrete repair materials use many types of raw materials, which lead to long preparation period, time-consuming and labor-consuming, and poor appearance quality, which greatly affects the construction quality, a concrete defect repair is proposed. Liquid and its preparation method, the ratio is simple, can be deployed on site, fast and effective, and after the use of each component, it plays a role of waterproof protection and improves the appearance of concrete components

Embodiment 1

[0020] The concrete defect repairing liquid includes waterproof material, color paste and black ink, and the mass ratio of the waterproof material, color paste and black ink is 1:(0.15-0.35):(0.05-0.25).

[0021] In this embodiment, the concrete is C30 concrete, and the mass ratio of the waterproof material, color paste and black ink is 1:0.3:0.1.

[0022] In this embodiment, the waterproof material is a water-based waterproof paint processed by an emulsification process using petroleum asphalt as a raw material and adding neoprene latex.

[0023] The present invention also discloses a preparation method of the above-mentioned concrete defect repair liquid, comprising the following steps:

[0024] Step 1: Add waterproof material and color paste into a 10L capacity bucket at a mass ratio of 1:0.3 at a normal temperature of 16-23°C;

[0025] Step 2: Use a stirring rod to stir clockwise for 5 to 10 minutes. After standing for two minutes, dip it with a wool brush and apply it on...

Embodiment 2

[0031] This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference lies in:

[0032] The concrete is C40 concrete. On the one hand, the mass ratio of the waterproof material, color paste and black ink is 1:0.2:0.2; on the other hand, the mass ratio of the waterproof material and color paste in step 1 is 1 :0.2.

Abstract

The invention discloses a concrete defect repairing liquid which comprises a waterproof material, color paste and black ink, and the mass ratio of the waterproof material to the color paste to the black ink is 1: (0.15-0.35): (0.05-0.25). The invention also discloses a preparation method of the concrete defect repairing liquid, which comprises the following steps: adding the waterproof material and the color paste into a 10L capacity barrel according to a certain mass ratio at the normal temperature of 16-23 DEG C; adopting a stirring rod for stirring clockwise for 5-10 minutes, after standing for two minutes, adopting a wool brush for dipping and coating on a color palette, and after airing, observing the color difference between the repairing material on the color palette and a concrete member; continuously stirring, anticlockwise stirring for the second time, taking a certain amount of black ink, and adding a proper amount of ink according to the color difference value; and dipping and coating the color palette with a wool brush, airing, and comparing with the concrete member again until the color difference requirement is met. According to the concrete defect repairing liquid and the preparation method thereof, the proportion is simple, and the concrete defect repairing liquid can be blended on site and is rapid and effective.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete defect repair liquid and a preparation method thereof. Background technique [0002] Concrete is referred to as concrete for short, which refers to the general designation of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, concrete refers to cement as the main cementitious material, mixed with water, sand, and stones, and chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, uniformly stirred, densely formed, and cured and hardened. artificial stone. The strength grade of concrete is divided by the standard value of cubic compressive strength. The strength grade of ordinary concrete in China is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80 . [0003] Currently used large-scale public buildi...
