SMF is a Melamine based High Range Water Reducing Superplasticizer for concrete mixtures. Use of SMF increases strength and or workability of concrete mixture. For normal concrete, up to 40 saving in cement consumption can be achieved through use of SMF. SMF-20 & SMF-40 grades are Type-F Superplasticizers for high early and final strength, while SMF-20S & SMF-40S are (Type G) High Range Water Reducing grades with addition set retarding characteristics.
