Performance Principle and Construction Application of Liquid Lithium Silicate Concrete Curing and Dustproof Agent

With the upgrading of industrial floor standardization, ordinary concrete floors generally suffer from problems such as sanding, low strength, multiple pores, and poor wear resistance, making it difficult to meet the needs of high-standard sites such as factories, warehouses, and supermarkets. Liquid Lithium Silica, as a new generation of inorganic silicate floor treatment material, is a high-performance concrete curing dustproof agent that combines hardening, dustproof, sealing, and wear-resistant functions. Different from traditional sodium-based and potassium-based silicate sealing materials, the lithium silicate system has stronger stability, a lower alkali leaching rate, and a longer hardening effect, making it the mainstream silicate concrete sealant. The core principle is to penetrate into the interior of concrete and undergo secondary reactions with hydration products such as dicalcium silicate, fundamentally sealing pores and solidifying the matrix. It is widely used in various liquid floor renovation and new construction solidification projects.

Core performance advantages of liquid lithium silicate

Liquid lithium silicate concrete curing dustproof agent belongs to water-based inorganic liquid materials, which are non-volatile, pollution-free, environmentally friendly and safe. Compared with traditional floor curing materials, it has significant comprehensive performance advantages and is suitable for modern green industrial floor construction standards.

1. Deep penetration solidification, significantly improving overall strength

Liquid lithium silicate molecules have a small particle size and strong permeability, and can penetrate 3-5mm deep into the surface of concrete without just staying on the ground to form a paint film. After material penetration, it will continuously react with the partially hydrated dicalcium silicate and free lime in the concrete to generate dense and stable silicate gel crystals, effectively fill the capillary pores of the concrete, greatly improve the overall compactness, compressive strength and surface hardness of the floor and thoroughly improve the sanding, softening and pulverization of the ground.

2. Long-term dust-proof seal, excellent impermeability and stain resistance performance

After the lithium silicate curing treatment, the internal pores of the concrete floor are completely blocked by gel materials, forming a dense overall sealing structure, blocking the water vapor, oil and dust infiltration channels. The ground is no longer dusty or sandy, and it has good waterproof, anti-seepage, and oil stain resistance. Daily cleaning is simple and convenient, and the ground can be kept clean and flat for a long time, perfectly solving the pain points of ordinary concrete floors that are prone to dust accumulation, easy to infiltrate, and difficult to maintain.

3. Low alkali content, high stability, and stronger durability of the floor

Traditional sodium-based and potassium-based silicate curing agents are prone to problems such as alkali bleeding, whitening, later frosting, and surface powdering, which affect the appearance and service life of the floor. Liquid lithium silicate has stable chemical properties, mild and long-lasting reactions, is not easy to precipitate alkaline substances, and has an extremely low probability of alkali leaching. The hardness of the formed floor continues to increase, and it becomes more wear-resistant with use. It has excellent resistance to aging and alternating high and low temperatures, and its service life can reach more than 20 years, far exceeding that of ordinary floor treatment materials.

4. Wide environmental adaptability, without changing the original texture of the ground

This product is a water-based inorganic formula that is VOC-free, odorless, non-toxic and harmless and meets industrial environmental protection construction standards. After construction, there is no film covering, no peeling, and no change in the original air permeability of the concrete. The natural texture and anti-slip performance of the ground are preserved, and it can be polished to achieve a high gloss and transparent effect, balancing practicality and aesthetics. It is suitable for various commercial and industrial sites.

Analysis of the Mechanism of Core Hardening Reaction

The hardening, dust-proof, and sealing effects of liquid lithium silicate are achieved through its chemical reaction mechanism with concrete substrates. The core revolves around the secondary reaction of dicalcium silicate hydration, which is also its core advantage compared to ordinary floor coatings.

1. Reaction of concrete substrate foundation

During the solidification process of ordinary concrete, the dicalcium silicate in cement undergoes a basic hydration reaction, generating hydrated calcium silicate and calcium hydroxide. Among them, calcium hydroxide has a strong free nature and poor stability, which is the main reason for sanding, alkali bleeding, multiple pores, and insufficient strength on the ground. It is also the core hidden danger of later powdering and damage to the floor.

2. Secondary solidification reaction of lithium silicate

After the liquid lithium silicate penetrates into the concrete pores, it will continue to undergo secondary polymerization with the free calcium hydroxide in the base material and the partially hydrated dicalcium silicate and generate a hydrated lithium silicate gel that is insoluble in water, compact in structure and extremely stable. The gel material will firmly fill and seal the concrete pores and cracks, solidify the loose concrete matrix into a compact whole, complete hardening and sealing transformation from the microstructure, and achieve permanent dust-proof, hardening, and wear-resistant effects.

Standardized construction process flow

The solidification effect of liquid lithium silicate flooring is closely related to the construction process. A standardized construction process can maximize material performance and ensure the quality of flooring molding. The standard construction steps are as follows.

1. Ground Base Preparation

Clean up dust, oil stains, debris, and residual coatings on the ground, and repair and level areas with severe sanding, hollowing, and cracks in advance. Using a professional floor polishing machine to polish the ground as a whole, removing surface floating slurry, opening up concrete capillary pores, creating favorable conditions for material infiltration reaction, thoroughly vacuuming and cleaning after polishing, and keeping the ground dry and clean.

2. Material Coating, Penetrating and Curing

Evenly roll or spray the liquid lithium silicate curing agent onto the ground to ensure that the ground is fully immersed, without water accumulation or missed coating. Keep the ground moist for 2-4 hours to allow the material to fully penetrate and react, ensuring a deep solidification effect. If the ground is loose and porous, a secondary coating can be applied to enhance the hardening and sealing effect.

3. Polishing and Finished Product Maintenance

After the material is completely dried and reacted, it is sequentially polished and polished using coarse and fine grinding discs to remove residual substances on the surface and improve the flatness and glossiness of the ground. Within 24 hours after the completion of construction, heavy objects are prohibited from crushing or soaking in accumulated water. Natural curing should be completed within 7 days, and the strength of the floor will continue to steadily improve, ultimately forming a dense and wear-resistant cured floor.

Mainstream engineering application scenarios

With stable performance and a simple construction process, liquid lithium silicate solidified dust inhibitor is suitable for various industrial and commercial liquid floor renovation projects, with a wide range of applications. In the industrial field, it can be used for hardening and dustproof treatment of factory workshops, warehouses, parking lots, logistics yards, and equipment room floors; Commercial scene adaptation for large-scale supermarkets, exhibition halls, office buildings, and public area ground renovation; At the same time, it can be used for sealing and curing protection of new and old concrete pavements, terraces, and basement floors, effectively solving the problems of dusting, sanding, and insufficient durability of various concrete floors.
