Powerfix MN-531 Melamine Superplasticizer Admixture, 250 L, Grade Standard: Technical Grade

Description:
- MN Plasticizer-531 is based on processed melamine. It acts as both a set-retarder and as a plasticizer. When added to concrete mixes the admixture is absorbed onto the cement particles. It then acts as a dispersing agent which breaks down agglomerates of cement particles and enables the water in the mix to perform more efficiently. It delays the initial hydration of the cement which results in retardation of the setting time. As a retarder, it can be used to extend setting time in high ambient temperatures, where mass concreting is involved such as foundations, water retaining structures, silos, piles and slip from structures where long delays or interruption can lead to problems or where cold joints have to be avoided. As a plasticizer, Cement reduction up to 10% is possible for a given workability and strength. Hardening: At higher temperature concrete hardens more rapidly and may impose problems with placing and finishing of concrete.
Use:
- It can use with all types of Portland cement. As a retarder, it can be used to extend setting time in high ambient temperatures, it can be used to increase workability without addition of water or obtain increased strength by reducing water content for a given workability.
Benefits:* Extends setting time & provides protection against delays and stoppages.
* Avoids cold joints
* Increases workability makes placing, compaction and finishing easier and better.
* Increases strength due to reduction in water
* Facilitates keeping a workable concrete face under difficult condition.
* Can be used with pump concrete and bricks manufacturing Chloride free.
