Concrete hardener with silicon crystals

Abstract

The invention relates to a concrete hardener with silicon crystals. The concrete hardener comprises silicate mixtures, nanometer silica sol and organic solvents. According to the scheme, the concretehardener with the silicon crystals has the advantages that the concrete hardener can be permeated into concrete, continuous chemical reaction can be carried out on the concrete hardener and the concrete, non-expansion, non-contraction and high-strength vitreous compounds with stable properties can be generated, concrete matrixes can be reinforced, sealed and hardened to form compact integral structures, the strength of the compact integral structures can be continuously reinforced along with the passage of time, and accordingly effects of sealing the hardened, strong, impervious, weather-resistant, abrasion-resistant, dust-free, efflorescence-free and gorgeous concrete which has enhanced chemical resistance and is firm just like steel can be realized; the concrete hardener is waterborne liquid and is safe and environmentally friendly; the concrete hardener is applicable to diversified new and old concrete floors including raw stock floors, terrazzo floors, carborundum abrasion-resistant floors and the like, and excellent effects of hardening and reinforcing loose floors with severe dusting can be realized by the concrete hardener.

Description

technical field [0001] The invention relates to a concrete hardener, in particular to a concrete silicon crystal hardener. Background technique [0002] At present, concrete structures have been widely used in the field of construction, but the inherent defects of concrete structures have become the main factor affecting the life cycle of concrete; alkali aggregate reaction (ASR) refers to the cement, admixtures and water in the raw materials of concrete The alkali reacts with the active components in the aggregate, and gradually reacts after the concrete is poured. The product absorbs water and expands to cause internal stress in the concrete, causing the concrete to expand and crack, and lose the design performance; the adverse reaction of ASR is currently recognized worldwide as "concrete structure In addition, the concrete structure also has the defects of easy ash, poor wear resistance and low hardness. [0003] To overcome the above deficiencies, there are generally t...

Problems solved by technology

[0007] At present, there are three generations of hardener products. The first generation is a sodium-based product based on sodium silicate, the second generation is a potassium-based silicate hardener, and the third generation is a lithium silicate-based product; the first two generations have limited capacity. To improve the hardening of concrete, the third-generation product is the only material that can effectively reduce the ASR reaction, but because the third-generation product still has technical limitations, the improvement effect is not obvious

[0008] For example, a concrete hardener and its preparation method disclosed in the Chinese patent application publication number "CN103864341A", this kind of hardener has a short setting time and a high Mohs hardness, and it also has a certain mitigation effect on the ASR reaction. However, this hardener is expensive and not suitable for mass production
