Scope of application:

Type 100-II water reducing admixture is widely applied in concrete projects,especially adaptable to the following:foundation concrete,mass concrete,flowing concrete,self compacting concrete,pumped concrete,steam curing concrete,natural curing precast concrete,reinforced concrete and pre stressed concrete and high strength concrete.

USage:

Addition:The addition of type 100-I admixture is 0.5-1.0%,the general addition is 0.75%.When preparing low grade concrete or adopting slag cement,please select and use the amount of 0.4-0.6% to save cement and improve economic benefits;while preparing high grade and pre srtessed concrete,please select and use the amount of 0.75-1.0%.

Packing and storing:

1)Powder water reducing admixture type 100-I is 25Kg/bag,packed in plastic bag internally and in woven bag externally.

2)The powder admixture shall be kept in dry place with precaution against dampness.But the damped powder will not be affected on its effect,and can be used after proportioned to water solution.

3)Powder water reducing admixture type 100-I has a service life of two years,water reducing admixture beyond its service life can be used again after concrete trial mix testing.
