Manufacturing cement is an energyintensive process. It requires 3 to 6 million BTUs (British thermal units) of energy and tons of raw materials, mostly limestone, to make one ton of clinker. Coal or coke is typically used to fire the kilns that are used to burn the limestone, clay, shale, and other materials; the materials must be heated ...

The Process for Making Portland Cement. Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, sandstone, marl, shale, iron, clay, and fly ash.
Mortar. Mortar is used to hold building materials such as brick or stone together. It is composed of a thick mixture of water, sand, and cement. The water is used to hydrate the cement and hold the mix together. The water to cement ratio is higher in mortar than in concrete .

Soilcement is sometimes called cementstabilized base, or cementtreated aggregate base. Regardless of the name, the principles governing its composition and construction are the same. What Type of Soil is Used? The soil material in soilcement can be almost any combination of sand, silt, clay.
Cement is the combination of calcium carbonate, silica, alumina and ferrous oxide, which are naturally found in limestone rock, chalk, shale and/or clay. During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter.
Common among the materials used in its manufacture are limestone, shells, and chalk or marl combined with shale, clay, slate or blast furnace slag, silica sand, and iron ore. Each step in manufacture of portland cement is checked by frequent chemical and physical tests in plant laboratories.
A Sears backyard cement mixer, which sells for 330 (with motor), can be altered to process clay satisfactorily. It will not mix clay as fast or as thoroughly as the blade mixers, nor will it efficiently blend clay powder with slip or dried clay chunks, but it does produce good quality clay with vastly less time and effort than hand methods.
