William had discovered that a significantly different product, with much wider applications, could be made by modifying his father's cement formulation. By increasing the limestone content in the mixture, and burning it much hotter, a slow-setting, high-strength product suitable for use in concrete could be obtained.
Cement powder in a bag, ready to be mixed with aggregates and water. [1] Cement block construction examples from the Multiplex Manufacturing Company of Toledo, Ohio, in 1905. A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together.
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.).

The cement was made from natural nodules of chalk and clay ("septaria") from the Isle of Sheppey. From around 1807 a number of people looked to make artificial ...
