SikaControl®-730 WT

(former MasterLife® WP 730)

Hydrophobic pore-blocking ingredient for watertight concrete

SikaControl®-730 WT is a hydrophobic pore-blocking ingredient (H.P.I.) for concrete. It significantly reduces water absorption of concrete.
SikaControl®-730 WT is a chloride free organic admixture and supplied as a clear to slightly cloudy liquid. It reacts with the cement hydration process to form a hydrophobic ingredient to reduce the capillary suction and prevent the ingress of potentially deleterious soluble material, resulting in concrete with enhanced durability.

  • Very low water absorption - Increased durability and water tightness.
  • Integral system - Protection is maintained through out the concrete matrix.
  • Ammonia free - Environment friendly. Fully compatible with certain surface coating and finishes.

System information

Compatibility

SikaControl®-730 WT should not be pre-mixed with other admixtures. Sika® Plastiment®, SikaPlast® or Sika® ViscoCrete® admixtures used in concrete containing SikaControl®-730 WT must be dispensed separately.
Consult the Sika Technical Services Department for advice.
Technical Information

Curing Conditions

Like all cementitious products, concrete made with SikaControl®-730 WT must be protected against rapid drying due to high temperature and / or strong wind.

The use of wet hessian, plastic sheets or a curing compound is highly recommended.

Application

Application Information

Dispensing

SikaControl®-730 WT should be added separately to the initial batching water to ensure complete distribution throughout the mix. Use only drinkable water - do not use seawater, bore water or water containing a high dissolved mineral of content, for mixing concrete.
Consumption

Recommended Dosage

The optimum dosage for SikaControl®-730 WT to meet a specific requirement should always be determined by trial mixes.
Typical dosage rate is 1.0 to 2.0 litres per 100 kg of cement. Other dosages may also be used depending on the specific requirements.
Consult local Sika field representative for assistance in determining dosage.
