Problems solved by technology

Sand consolidation agents currently on the market are mainly divided into two categories: organic and inorganic. Among them, organic sand consolidation agents are mainly polymer resins. This type of sand consolidation agent usually has a higher molecular weight and greater viscosity. Make the loose ash and sand on the concrete base surface form a larger stable body; but the polymer sand consolidation agent also has defects such as poor heat resistance, flammability, and aging resistance. Under the long-term action of heat, oxygen, and light , the polymer degrades, its physical and chemical properties and mechanical properties gradually decrease until it fails completely, so the service life is short
At present, the inorganic sand consolidation agents on the market are mainly silicates, which are usually stable in nature, low in price, non-toxic and harmless, have a long service life, and do not contain volatile organic substances. It has little impact on the environment; but because of its fast reaction speed and poor permeability, it cannot fully complete the curing reaction on the concrete base surface, and the strength of the sand-fixing layer is low, which is easily damaged by the external environment

Abstract

The invention discloses an inorganic water-based permeable sand consolidation agent and a preparation method thereof. The inorganic water-based permeable sand consolidation agent is prepared from, byweight, 40-50 parts of a sodium silicate solution, 2-5 parts of a curing agent, 0.05-0.25 part of a surfactant, 0.8-2 part of a surface hardening agent and 40-50 parts of deionized water. Sodium silicate is used as a main component, a sand layer can be solidified by utilizing a self solidification reaction, and stable silica gel is generated through a synergistic effect formed by compounding witha curing agent so that sodium silicate forms a layer of compact silica gel film on a concrete base surface to achieve the purpose of sand solidification, and meanwhile, a dispersion effect can be achieved, agglomeration of sodium silicate colloidal particles can be effectively hindered, the sodium silicate is kept in a nanoscale size and permeation in concrete is facilitated.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an inorganic water-based penetrating sand consolidation agent and a preparation method thereof. Background technique [0002] As a widely used building material, concrete plays a huge role in modern construction engineering technology. However, due to problems such as the quality of the base surface material, concrete mix ratio, construction operation, and insufficient maintenance, concrete often has the problem of ash and sand, which seriously affects the performance of concrete and the subsequent construction process. [0003] Internationally, since the 1930s, some people have been engaged in the development and application of sand-consolidating agents. The main purpose of the research at that time was to control the quicksand on both sides of the desert road and avoid the damage of storms. Due to the limitations of the level and conditions, the sand consolidation agents at t...
