	Concrete curing agentMRK-20(Sodium)	Form: LiquidBurning point: NoToxicity: No, without any venomous material composition. Color: As clear as crystal, has little light color.Active ingredient:100%Density:1.19g/cm3Penetrate ability:MRK-20,21:2mm-6mmPressive strength:The average increase of MRK-20,21 is above 38.8%The average increase of MRK-22 is above 49.6%Wearing strength:The average increase of MRK-20,21 is above 47%Curing time: About 60 days, it can reach the overall effect of solidification above 40% within 2 hours after painting the curing agent, so this period is very important.Hardness:MRK-20,21 can increase 19%-180%Anti-impact ability:Increase above 18%Wear corrosion resistance: Test proof, curing after 28 days, resistance to acid and alkali. Usage temperature: It’s available when above 3°C.To prevent the concrete cracking ability, increase above 90%.Water retentivity: Increase above 90%.Expand the life of concrete 100%-150%.The use of curing agent amount is 0.2-0.33kg per square meter, below 0.2kg is not suitable; amount is different according to different cement grade.	Merrock’s curing agent can react to the concrete, harden and seal the concrete. It not only can keep sclerotic and sealed effect durable for concrete to efficiently extend the concrete life, but also can prevent the concrete weathering, it’s dustproof, acid-proof, alkali-proof and antipollution, especial no need repeated maintenance after completing the construction, and it’s very low in use-cost.At present, this item widely use in: industrial factory building, parking lot, airport, dock, port, hypermarket, warehouse and distribution center, school, cool house, gym, hospital, community, Brand monopolization, factory, urban construction, road and bridge and logistics center etc. place.
