Problems solved by technology

However, in this precedent, the main component of the texture modification material is sodium silicate monomer, which reacts very quickly with the calcium in the coagulation surface, and will generate dust and gel in a short time, resulting in (such as image 3 As shown) the texture modification material 1' can only penetrate to the very shallow position (about 45mm) of the crack 3 of the concrete 2, so the texture modification material 1' has little effect
Moreover, in the construction proces...

Embodiment Construction

[0014] Below in conjunction with embodiment further illustrate the present invention:

[0015] First, take a certain amount of sodium silicate and potassium silicate, mix them according to the molar ratio of 1:1, make a concentrated solution and then dilute with water, then add sodium hydroxide to the mixed solution of sodium silicate and potassium silicate , stir for about 1 hour. Then, it was filtered through a 3 μm filter to produce a concrete texture modifying material. This concrete modification material is an alkaline silicate mixed aqueous solution containing two elements, sodium and potassium. Apply this concrete modifying material on the surface of the concrete, and apply it on the surface of the pores to protect it. If there are continuous pores in the concrete, such as figure 1 As shown in (a), due to the capillary phenomenon, the reforming material penetrates deep into the continuous pores (voids) of concrete (about 200 mm), gels inside the pores, and fills the ...

Abstract

The present invention relates to a concrete texture modifying material and the preparing method thereof, at least two materials are selected from sodium silicate, potassium silicate, lithium metasilicate are selected for mixing, and the sodium hydroxide are added into the mixed liquid. The method for making the concrete texture modifying material is respectively choosing at least two materials from sodium silicate, potassium silicate, lithium metasilicate for mixing with a molar ratio 1:1, then adding sodium hydroxide into the mixed liquid, and then is prepared by filtering after stirring for a certain time. The advantage of the invention is that the velocity of gelatinization can be adjusted by adjusting the adding amount of sodium hydroxide in the mixed liquid, the deterioration of concrete caused by the entering of the air is prevented by permeating the mixed liquid into the slit of the concrete for gelatinization according to the condition of the concrete deterioration, the acid can be neutralized and the concrete deterioration can be prevented. Meanwhile the function of mixed alkali is used for preventing alkaline framing member reaction, salt damage, freezing dissolving and the like.

Description

Technical field: [0001] The present invention relates to a concrete texture modifying material and a manufacturing method thereof, such as a structural body of a building, a frame or a bridge, a tunnel, and a concrete secondary product such as prefabricated concrete and a liftway, etc., and a manufacturing method thereof. Background technique: [0002] Concrete is widely used in various fields such as civil engineering and buildings because of its high compressive strength, ability to support heavy loads, making it into any shape, excellent performance in fire resistance, heat resistance, durability, etc., and relatively low price. middle. However, after the concrete is manufactured and molded, the moisture contained in the curing process evaporates, and cracks are generated due to drying shrinkage, and cracks are also generated due to the corrosion of steel bars and the reaction of alkaline aggregates. Therefore, there are many continuous pores composed of pores with a lar...
