Melamine Plasticizer For Rubber Mould Paver Block
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.
