It has good adaptability to cement variety, less air entraining, and remarkable water-reducing and intensifying effect.
Type TJ-FDN-106 Retarding High-effective Water-reducing Admixture
Main Technical Performances
1. Type 106 is divided into power admixture and liquid admixture. The power admixture is chocolate brown; and the liquid admixture is brownish black. It has no toxicity or pollution, and is not inflammable.
2. The addition amount of type 106 powder high-effective water-reducing admixture of is 0.5-1.0% of cementing materials used; the amount of liquid admixture is 1200~2500ml/100kg cementing materials; water-reducing rate is 13-23%; the general amount of addition strength can be increased by 30-50% in twenty eight days.
3. Under the same water-cement ratio, the initial slump of concrete can be improved by over 10cm by adding 0.75% admixture, which is suitable for making high-strength pumping concrete.
4. On the precondition of keeping the design strength of concrete, adding type 106 can save cement 15-20%.
For example: Use Evergreen P.042.5-level cement, natural medium sand of 2.81 fineness modulus, the artificial gravels of Φ5~31.5mm continuous graduation and compressive strength of not less than 80Mpa, and drinking water, to prepare C40-level concrete, such as concrete for the bearing platform of bridge main piers (Only for Reference)

3 Days | 7 Days | 28 Days | |||||||
Benchmark | 476 | 603 | 1173 | 200 | —— | 110 | 20.0 | 35.1 | 49.2 |
Admixture | 400 | 718 | 1172 | 160 | 3.2 | 120 | 36.5 | 45.2 | 54.6 |
5. Type 106 retarding high-effective water-reducing admixture is very applicable to the following concrete engineering:
Pumping Concrete; Fluidized Concrete; Self-compacting Concrete; Hydraulic Concrete; Prestressed Concrete; High-strength Concrete
Usage
1. Add 0.5~0.75% type 106 (calculated as dry power) to prepare early strength concrete and high strength concrete; Add 0.75~1.0% to prepare C40~C60 pumping concrete.
2 Type 106 power admixture can be prepared into solution with a certain concentration or directly added.
Best Method of Adding Admixture
When you first use this product or are to change the variety of cement, please make necessary trial mix testing for the amount and method of adding admixture, according to engineering requirements and conditions and referring to above instructions.
