XF Accelerator Admixture

XF Accelerator Admixture
1. Operative Norm
The performance follows the standard JC477-2005< Accelerator Admixture Used for on spray concrete>

2. Characteristics
Appearance Power
Rate of Water Content ≤ 2%
Fineness (0.315mm sieve residue) ≤ 15%

3. Performance
*Obvious affect, early condensing time≤ 5min finally condensing time ≤ 10min
*The affect of spraying is good, little rebound degree and save material, obvious economic benefit.
*Good glutinous a hick spray, spray arches up to 130mm. 4 As to the spray concrete, the early strength is high, later affect would reduce, the strength could conserve 80% after 28d.
*Contain tiny quantity of alkali, non-toxic, incombustible, no corrosion to the steel.

4. Application
Use for spray concrete and mortar of the national defense, irrigation work, lane, tunnel, subway, and other under ground constructions, also include spray mortar, conservation work of waterproof construction, anti-permeability, and fast construction of the ground concrete, emergency rescue construction with concrete.

5. Use Method
*Quantity: 3-6% of the cements usually is 4%; Make the adaptability to the cements before used
*Agitate the mix materials homogenous, add water and rapid setting agent at the spray point and agitate, and then it is ready to spray. Advise to test the condensing time before using.
*Package and Storage
25kg/bag, liner plastic membrane. Store at the dry places, best used in 5months.

6. Attentions
*Please choose fresh cements conform to the country standard, don't use the cement which had been over the standard period or become wet blocks.
