STENPC 50% HWR ( Polucarboxylate Ether Liquid 50% ) High Water Reducer

 STENPC 50% Liq (HWR) is a superplasticising Liquid to produce flowable or pumpable concrete and mortar for all grades, without bleeding and segregation.

 It is formulated from synthetic polymers specially designed to impart the cohesiveness to the concrete mix for easy pumping and placing. It considerably improves the properties of fresh and hardened concrete and mortar.

Primary uses to obtain:

 High workability

 Higher early & ultimate strengths

 With congested reinforcement

 Increases durability & impermeability

 Lower pumping

Area of Application:

 Precast / Pre-stressed Concrete

 Readymade mortar

 Casting in hot climates

 Pumped concrete

Method of Application:

 Add correct quantity of STENPC 50% Liq (HWR) by weight to cement along with other aggregates. Mix thoroughly and then add measured water. Allow to mix it for recommended mixing time.

Dosage:

 As a starting point, a dosage range of 0.1 kg to 0.3 kg per 100kg of Cementitious materials is recommended. Optimum dosage of STENPC 50% Liq (HWR) should be determined in trial mixes. Please consult StenfyChem. Technical staff for further information.

Effects of Over-dosage:

A severe over-dosage of STENPC 50% Liq (HWR) will result in the following:

Retardation of Setting Time

Increase in workability / segregation

Slight increase in air entrainment
