SikaControl®-730 S WT

(former MLife WP 730S)

Hydrophobic pore-blocking admixture for watertight concrete production

SikaControl®-730 S WT is a hydrophobic poreblocking admixture for concrete. It significantly reduces water absorption of concrete through its pore-blocking and hydrophobic actions. SikaControl®-730 S WT 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. Suitable for use in hot and tropical climatic conditions.

SikaControl®-730 S WT waterproof admixture in concrete has the following advantages:
▪ Improves significantly concrete water impermeability
▪ Improves concrete durability
▪ Reduces ingress of sulfates and carbonation
▪ Reduces leaching
▪ Chloride free
▪ Ammonia Free

Technical Information

Concreting guidance

With the use of SikaControl®-730 S WT, the standard rules of good concreting practice (production as well as placing) must be observed.
Fresh concrete must be cured properly, especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

 

Application

Application Information

Dispensing

SikaControl®-730 S WT should be added directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle or along with the mix water. The concrete should be mixed thoroughly until a homogenous concrete mix is produced.
Recommended minimum cement content is 380 kg/m3 including PFA, GGBS, and Silicafume
▪ Recommended water/cement ratio ˂0.45
▪ SikaControl®-730 S WT has no significant water reducing or slump keeping properties
▪ Do not add SikaControl®-730 S WT to dry cement.

Compatibility

SikaControl®-730 S WT is suitable for mixes containing all types of cement including Sulphate Resistant Cement (SRC) and supplementary cementitious materials such as Microsilica (Silica Fume), Fly Ash (PFA), GGBS (ground granulated blast furnace slag), all normal types of retarders, plasticizers and superplasticisers and the following Sika products:
SikaPlast®, Sika® ViscoCrete®, Sikament®, Plastiment®, SikaPump®, Sika® FerroGard®
We recommend to perform trial mixes to establish the required performance when combining SikaControl®-730 S WT with the above products or other admixtures. Please consult our Sika Technical Department.
Consumption

Recommended dosage

0.5 – 2.0 litres per 100 kg cement. However, the optimum dosage to meet project requirements must be determined through trial mixes.
