This type of cement is used a lot today, and is still known as OPC (ordinary Portland cement) ... It is ground up into a powder to form ordinary OPC
Rapid heat cement
They generate more heat in the early stages and can be useful in cold weather concreting. ... as either rapid-setting or extra rapid hardening may be
Low heat cement
Low Heat Cement complies with AS 3972, Special Purpose Type LH/SR. It is manufactured from the ingredients of specially selected cement clinker and ground granulated blast furnace slag, that result in significantly lower heat generation during the process of hydration than the comparable Portland Cement.
Portland blast furnace cement
The granulated slag made by the rapid chilling of suitable molten slags from blast furnaces forms the basis of another group of constructional cements. A mixture of portland cement and granulated slag, containing up to 65 percent slag, is known in the English-speaking countries as portland blast-furnace (slag) cement.
High alumina cement
of High Alumina Cement, Alumina Cement, Refractory Cement, Refractory Materails, ... Density Corundum Bricks, high alumine cement ca50-G5, G7, G9, fused, ca70, ca80
Expanding and nonshrinking cements expand slightly on hydration, thus offsetting the small contraction that occurs when fresh concrete dries for the first time. Expanding cements were first produced
Quick setting cement
Rapid cure allows for quick access to repaired areas. Garonite anchoring cement sets and expands rapidly, curing twice as strong as concrete in one hour. Use indoors or out
Air & trading cement
Cement is a hydraulic bonding agent used in building construction and civil engineering. It is a fine powder obtained by grinding the clinker of a clay and limestone mixture calcined at high temperatures. When water is added to cement it becomes a slurry that gradually hardens to a stone-like consistency. It can be mixed with sand and gravel (coarse aggregates) to form mortar and concrete.
There are two types of cement: natural and artificial. The natural cements are obtained from natural materials having a cement-like structure and require only calcining and grinding to yield hydraulic cement powder. Artificial cements are available in large and increasing numbers. Each type has a different composition and mechanical structure and has specific merits and uses. Artificial cements may be classified as portland cement (named after the town of Portland in the United Kingdom) and aluminous cement
White portland cement is readily available throughout North America. It has essentially the same properties as gray cement, except for color, which is a very important quality control issue in the industry.
The color of white cement depends on raw materials and the manufacturing process. It is the metal oxides (primarily iron and manganese) that influence the whiteness and undertone of the material. White cement is manufactured to conform to ASTM C 150, Specification for Portland Cement. Although Types I, II, III, and V white cements are produced, Types I and III are the most common.
White cements produce clean, bright colors, especially for light pastels. Many different colors can be created by adding pigments to concrete made with white portland cement. Two or more pigments can be combined to achieve a wide range of colors. White cement (or a mixture of white and gray cement) can be specified to provide a consistent color of choice. An even greater variety of decorative looks can be achieved by using colored aggregates and varying the surface finish treatment or texture.
