SikaPlast® Eco-80 SK

MWR – Mid-Range Water reducer

SikaPlast® Eco-80 SK is a water reducing and workability-retaining admixture specifically formulated for extended slump life in concrete. SikaPlast® Eco-80 SK combines the benefits of a mid-range water reducer with a slump keeper to achieve extended slump life in 120-180 mm slump concrete.

SikaPlast® Eco-80 SK is a unique concrete admixture used to improve the workability and slump retention of concrete mixtures. SikaPlast® Eco-80 SK uses innovative polycarboxylate polymer technology, which can be used in various concrete applications whenever extended slump retention and concrete plasticity without excessive set time delays is required. Use of SikaPlast® Eco-80 SK delivers the following benefits to a concrete producer: ▪ Extended slump retention. ▪ Reduced or eliminated need for concrete re-tempering. ▪ Optimized concrete mix design resulting in cost savings. ▪ Ability to adjust the slump retention accordingly to transportation time and temperature. ▪ Reduced rejection rates due to issues related to concrete re-tempering.

Application Information

Dispensing

Add SikaPlast® Eco-80 SK to the initial batch water. For best results we recommend thorough mixing of wet concrete. A minimum of 60 seconds mixing per cubic metre is recommended.

Do not add to a dry mix.

Compatibility

SikaPlast® Eco-80 SK can be used in conjunction with most of the Sika Concrete admixtures, with the exclusion of Sikament NN.

When used in combination with admixtures that might cause delay, specific site trial shall be done.
Consumption

Recommended dosage

Typical dosage for general concrete production is between 400-1000ml per 100kg of total cementitious material. Optimum dosage depends on site conditions, mix ingredients and desired plastic and hardened properties. Laboratory and field trials are essential in determining the optimum dosage.
