Magnesium sulfate is an essential construction-grade chemical compound used primarily as a set retarder in cement, gypsum, and plaster systems. It plays a critical role in extending the hydration process, allowing more time for mixing, placing, and finishing — particularly valuable in hot climates or large-scale concrete pours.
With high solubility, consistent particle size, and stable chemical behaviour, Magnesium Sulphate helps reduce early stiffening, enhance bond strength, and lower the risk of cracking or shrinkage. Whether in dry-mix formulations or on-site batching, it ensures optimal setting control, contributing to stronger, more durable structures.
