Product description

Report abuse

JLY-04 Concrete high-efficiency pumping agent is compounded with high-efficiency water-reducing agent and reinforcing agent, retarder, plasticizer, air-entraining agent and other components.Comply with GB8076-2008 “Concrete Admixture – Pumping Agent” standard. It is an admixture specially designed for long-distance transportation and on-site pumping of commercial concrete.

Homogeneity index:

Item: Index
PH: 6-7
Slurry fluidity: ≥200mm
chloridion: free
Water reducing rate: 15%-30%

Main performance:

• The liquid dosage is 1.0%-2.5% of total cementitious materials.
• Mixed with this product under the same water-cement ratio,can increase the slump of concrete by more than 10cm. Under the same amount of cement and the same slump, the strength of concrete can be increased by 40%-70% in three days, by 30%-60% in seven days, and by 25%-50% in 28 days.
• The loss of slump over time is small, which can meet the long-distance transportation of commercial concrete.
• Workability, water retention and cohesion are greatly improved, no delamination and no segregation.
• Initially there is a retarding effect. It can reduce the early hydration and heat release rate of concrete, which is beneficial to the pouring of large-volume concrete.
• The compressive strength, flexural resistance, tensile strength, impermeability and durability of concrete have been significantly improved.


• Please follow the "Concrete Admixture Application Technical Specifications" for construction.
• This product has retarding effect, and the dosage should be strictly controlled in field application
• Experiments should be carried out when using this product for the first time or changing the type of cement to obtain the best technical effect and economic benefit.
• This product is suitable for concrete construction under the environmental conditions of -1℃-50℃
