PORTLAND AND MASONRY CEMENTS
Portland Cement Type GU is a specially formulated Portland-lime cement. While regular Portland Cement may contain up to 5% limestone, Heidelberg manufactures it by inter-grinding regular clinker (the main ingredient in cement) with up to 15% limestone.
USES
Type GU Portland Cement is a normal, general use cement suitable for all uses such as: general construction projects, buildings, bridges, floors, pavement, basements, foundations, driveways, highways, culverts and pipes, reinforced concrete buildings, and other precast concrete projects.
Each 66lb (30kg) of Masonry Cement mixed with 3cuft of sand will produce 3cuft mortar.
After concrete is placed, between 10C and 24C (50F and 75F) adequate curing is vital. Freshly mixed concrete contains more water than required for complete hydration of the cement. Good curing of the cement means that evaporation should be prevented or reduced. Sprinkle surface with water fog or cover surface with moisture retaining fabrics such as burlap or cotton mats or even plastic spraying compound. The longer the concrete is kept moist, the stronger and more durable it will become.
Suitable for a binding agent in masonry cement and Portland/lime mortar. Portland is classified in five major categories called types. The type of cement is used in a project will depend on the application and the concrete’s performance requirements.
