Main technical performance and characteristics
1. HP-2 Concrete pumping agent dosage range of 1.5-2.5%, the specific dosage should be determined by experiment. Conventional dosage recommended as 1.6-2.0%.
(2) high water reduction, early and late strength increased significantly.
3 retarding time can be adjusted.
4 concrete slump good, especially for long-distance concrete transportation.
5 workability of concrete, easy pumping.
6 good water retention can reduce concrete bleeding, segregation.
7 reinforced concrete lining will not rust effect.
Using methods and precautions
1 This product can not be with naphthalene water reducing agent blend is shared with other additives are mixed with test must be carried out.
(2) In the initial use of the product or cement variety is changed with a trial ahead of the best, choose the best dosage.
3 in fly ash concrete mix. Slag admixture when active, water reducing agent dosage should be calculated in the total cementitious material.
4 concrete mixer blending the product should be asked to extend more than 30 seconds.
5 The water in sensitive products, be sure to be very accurate measurement.
Packing, storage
1. HP-2 Concrete pumping agent: drum or tank car, should pay attention to rain, water.
2. HP-2 Concrete pumping agent in the original sealed Packing cases, O β above can Storage6 months. Expired products should redo the concrete after passing the test before use.
Description: According to the actual requirements of the user and engineering. Sometimes needs a specific formula HP-2 Concrete pumping agent according to project specific requirements, the actual use of raw materials as well as the specific conditions of the site and determine the product dosage formulations. To bring the best concrete quality and the best value for money.

Using methods and precautions
1 are powder products, mixed with direct feeding and appropriate to extend the mixing time.
(2) If there is anhydrite and gypsum and cement do tune coagulant, the need to pay attention to its adaptability.
3 In the initial use or cement variety is changed ahead of the best trial match. Choose the best dosage.
4 According to site conditions and customer requirements compressive formulated into all water soluble products can also be configured as a carrier to increase the dosage of products to suit most site meter and artificial additives.
5 ratio in fly ash concrete with disabilities. Slag and other active admixtures when. Water reducing agent dosage should be calculated in the total cementitious material.
6 This product can be used with other additives such as early strength agent, Air-entraining agent, retarder, expanding agent, etc. used in conjunction with the use must be tried.
Packing, transportation, storage
1. HP series powdery pumping agent with external woven bag, plastic bag Packing. Should pay attention to rain, water, moisture.
2. HP series powdery pumping agent in good condition Storage Shelf life is 2 years. Expired products should redo the concrete after passing the test before use.
Description: According to the actual requirements of users and works, and sometimes demand specific formulations HP series powdery pumping agent, according to project specific requirements, the actual use of raw materials as well as the specific conditions of the site to determine the product dosage and recipes to bring the best concrete quality and the best value for money.
