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.

Recommended for use in slabs, beams, columns and areas of high steel congestion and sections to achieve impermeable, honeycomb free, high quality concrete. Highly recommended for roof slabs, water-tanks, basements, foundations, floorings, decks, dams, bridges, roads, etc. Also recommended for use in pumpable concrete.

Can also be used in pre-cast cement articles and/ or normal concrete work where cement saving up to 40% can be achieved through its substitution with fly-ash without compromising on final strength or quality of construction
