Key words: seal curing agent concrete floor, Lute concrete floor, lithium-based seal curing agent concrete floor and lithium-based seal curing agent concrete floor.
Detailed introduction of concrete sealing curing agent floor
The concrete sealing curing agent terrace is usually called concrete curing agent or concrete sealant terrace. 1942 was invented in America, and 1947 was widely used in America. Today, 60 years later, concrete sealing curing agent has become the most widely used hardening agent for concrete sealing and curing in the world, and it is one of the best products to increase the service life of external protective concrete.
In China market, only a few concrete seal curing agent floors are well made. That is, Nalute concrete sealing and curing agent terrace, Merris concrete sealing and curing agent terrace, Ansford concrete sealing and curing agent terrace, Shibei concrete sealing and curing agent terrace, Leask concrete sealing and curing agent terrace, etc. These concrete sealing curing agents all have good effects. .
Here, taking Lu Na concrete sealing curing agent floor as an example, the concrete sealing curing agent floor is introduced in detail as follows:
1, Overview of concrete sealing curing agent floor
1. 1 product description of concrete sealing curing agent floor
Concrete sealing curing agent is a colorless and transparent liquid, which is odorless, non-toxic, non-flammable and has strong permeability. It contains no VOC (volatile organic compounds) and is composed of inorganic substances, chemically active substances and silicides. The concrete seal curing agent floor products have passed the USDA evaluation of food standard of USDA.
1.2 working principle of concrete sealing curing agent floor
The sealing curing agent of concrete reacts with calcium hydroxide, moisture and compounds produced in the hardening process of concrete through effective penetration of 3~ 5mm to generate a kind of hydrated calcium silicate, commonly known as xonotlite glue, which makes the concrete become a compact whole. Increasing the concentration of xonotlite glue can improve the strength and density of concrete. At the same time, the crystals generated by xonotlite glue in the pores of concrete effectively block the pores in concrete, reducing the flow path of water, thus preventing solid and liquid impurities from entering concrete and increasing the corrosion resistance of concrete, but at the same time allowing gaseous water to flow freely, thus maintaining the "breathing" function of concrete. At the same time, it makes the ground produce higher gloss and increases the aesthetic effect of use.
1.3 product characteristics of concrete sealing curing agent floor
The concrete sealing curing agent penetrates into the concrete, which can harden and seal the concrete after forming gel, without dust and sand. Because it can penetrate into the concrete surface and blend with the concrete matrix, it can effectively play the role of lasting hardening and sealing. The use effect is over 20 years, so the concrete sealing curing agent will also play a role in preventing weathering.
2. Scope of application and conditions of use of concrete sealing curing agent floor
Suitable for new and old concrete, terrazzo, aggregate wear-resistant floor, cement mortar surface, gypsum and other cement-based building materials.
3. The concrete sealing curing agent layer is not applicable.
3. 1 concrete sealing curing agent floor is not recommended to be used alone in long-term acidic environment. Due to the influence of environmental temperature, contact time, density and concrete floor composition, it is difficult to determine the effect of chemical corrosion resistance.
3.2 Seal the curing agent concrete floor block with light volume or other stones with too many holes.
Creation.
4. Functions and related parameters of concrete sealing curing agent floor products.
4. 1 concrete sealing curing agent terrace can improve the compressive strength: after 7 days, the compressive strength of treated specimens is 40% higher than that of untreated specimens, and then it will increase with the passage of time.
4.2 The hardness of the concrete enclosed curing agent floor can be improved: the Mohs hardness of the test surface of the concrete block is 6, and the Mohs hardness after the enclosed curing agent treatment is 8.
4.3 Better curing of concrete sealing curing agent floor: In the most important 24-hour curing process, the water-holding capacity of the treated concrete block is improved by 94% compared with that of the untreated concrete block, and the concrete is permanently cured to prevent cracking and shrinkage, which is permanent and effective once used, and can save a lot of maintenance and maintenance costs.
4.4 The concrete sealing curing agent is completely dust-proof: after the concrete test block is treated with the concrete sealing curing agent for 2 hours, it will never produce dust, and the purification effect can be achieved without waxing.
4.5 Improve the impermeability of the concrete sealing and curing agent floor: in an area of 4.9 square feet treated with sealing and curing agent, wash it with a 7-inch diameter faucet, and the leakage rate is 0.022 ml per hour.
