ECMAPLAST 104 SPL is a high-quality, high-range concrete super plasticizer based on modified sulphonated naphthalene formaldehyde. It is a concrete super plasticizer used in addition to concrete. It disperses the cement particles, which then enhances the workability by many folds and also gives very high retardation.

High-Range Water Reducing cum Retarding Plasticizer


ECMAPLAST 104 SPL is chloride-free. It improves workability exponentially and gives increased strength. It has a very good slump retention and improves the quality.


The normal recommended dosage is 0.4% to 1.4% for 50 kgs bag of cement. The optimum dosage and compatibility of the admixture should be ascertained by a proper trial in the site. An over dosage will lead to retardation as the formulation is specially designed to give extra retardation. The initial strength of the concrete may be lesser, where as the 3rd day, 7th day and 28th day will not get affected. ECMAPLAST 104 SPL has to be added on wet concrete mix for best results. ECMAPLAST 104 SPL has moderate slum retaining ability hence can be transported to longer distance due to which cold joints and placing problem can be avoided.
