Mr. MALCO® Fixer 303 MALCO®PROOF MW+ 

MALCO® PROOF MW+ is high early strength, high range water reducing/superplasticising, admixture for precast concrete.It is an admixture of a new generation based on second-generation polycarboxylic ether polymer with high early strength gains. Itis free of chloride & low alkali, it is compatible with all types of cements. 

Recommended Uses

Suitable for making precast concrete elements at all workability’s including Rheoplastic or Super workable concrete having fluid consistence, no segregation, a low water binder ratio and consequently high early and long term strengths.

It may be used for producing Rheodynamic concrete. capable of self- compaction even in the presence of dense reinforcement without the aid of vibration, for making precast elements.

Used as an component of Zero Energy System. 

Used for Concreting in cold weather.

FEATURES AND BENEFITS

Achieve high early strengths.

Produces Rheoplastic and Rheodynamic concretes having a low water cement ratio.

Optimize curing cycles by reducing curing time or curing temperatures.

Eliminate heat curing.

Eliminate the energy required for placing. compacting & curing (Zero Energy System™).

Increase productivity/ reduction in cycle time.

Improve surface appearance.

Produce durable precast concrete elements.

Improved engineering properties, compared to traditional superplasticiser such as early and ultimate compressive and flexural strengths reduced shrinkage and low permeability

Chemistry and mechanism of action

MALCO® PROOF MW+ has a different chemical structure from the traditional PCE polymer based superplasticisers. The base PCE molecule used to formulate MALCO® PROOF MW+ was custom made using nano-technology to enable effective dispersion with minimum hindrance to hydration process. It consists of a carboxylic ether polymer with long side chains and short main chains At the beginning of the mixing process it initiates the same electrostatic dispersion mechanism the traditional hyperplasticisers but the short main chains facilitate quick start of hydration process Rapid absorption of the molecule onto the cement, particles combined with an efficient dispersion effect maintains workability yet exposes increased surface of the cement grains to react with water As a result of this effect, it is possible to obtain earlier development of the heat of hydration,rapid strength development of the hydration products and as a consequence,higher strengths at a very early age.

ZERO ENERGY SYSTEM:

Zero Energy System is based on a combination of the avant-garde admixture MALCO® PROOF MW+ and the innovative technology of Rheodynamic concrete. The Zero Energy System has been developed to help the precast concrete producer to rationalize his production process and save on energy costs combined with improved quality of the product and the working conditions

DOSAGE

Optimum dosage of MALCO® PROOF MW+ should be determined in trial mixes. As a guide, a dosage range of 400 ml to 1500ml per 100kg of cementitious material is normally recommended. Because of variations in concrete materials, job site conditions. and/or applications dosages outside of the recommended range may be required. In such cases, contact your local Malco® Solutions representative.
