Portland Slag Cement

Ocean india is led by a team of quality conscious management and employees whose main focus remains customer satisfaction. Our portland slag cement is put through a string of tests to ensure excellent compressive strength, good setting properties and other features. The unique features and premium quality of our portland slag cement is ensured to deliver best performance for construction purposes. advantages of our portland slag cement

portland slag cement has the incredible features of reduction in heat during hydration; increased lateral strength; improvement in workability leading into less bleeding; better interface with aggregates resulting into inhibition of aggregate reaction. This kind of cement is manufactured by grinding the clinker with blast furnace granulated slug (25% to 65%), and gypsum. These elements are ground to desired fineness.
