| Portland Cement (425 Grade) |
Portland Cement (425 Grade) is a type of cement that is used for heavy duty forming. The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened,can become a structural (load bearing) element.
Users may be involved in the factory production of pre-cast units, such as panels, beams, road furniture, or may make cast in situ concrete such as building superstructures, roads,and dams. These may be supplied with concrete mixed on site, or may be provided with "ready-mixed" concrete made at permanent mixing sites. Portland cement is also used in mortars (with sand and water only) for plasters and screeds, and in grouts (cement/water mixes squeezed into gaps to consolidate foundations, road-beds, etc). |
