Add the dry Portland cement into the mortar box first, pouring carefully to help minimize dust, and then add the required amount of water. Stir slowly, incorporating the water into the cement until a thick paste forms. If the slurry is too thick, add more water a few tablespoons at a time until the desired consistency is achieved.
Portland cement manufacturing is a threestep process: Cementmaking requires calcium, silica and small amounts of alumina and iron. Raw materials rich in these elements include limestone, sand and clay. They are quarried at the cement manufacturing plant or shipped from nearby. Limestone, the source of calcium, makes up about 80% of the raw

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregateChemistry&ensp·&ensp
Portland Cement The Portland cement is the most basic and the most commonly used cement in the world the Portland cement was formerly known as ordinary Portland cement and is made by adding gypsum into the clinker. Using the Portland cement, concr
Portland cement is a complex product made from very simple and abundant materials: limestone and clay (or shale). Very precise proportions of these two basic materials have to be mixed with some additions to create a raw meal with a precise chemical composition this will result in the production of clinker through the complex pyroprocessing presented in Figure 3.1.

2000317&ensp·&enspPortland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materials:
20191119&ensp·&enspThe 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.
Pretoria Portland Cement Company Limited, through its subsidiaries, engages in the production and sale of cement. It sells cement through its distribution network to the building and construction industry, concrete product manufacturers, and retail outlets, such as

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
Gray Ordinary Portland Cement. Our Gray Ordinary Portland Cement is a highquality, costeffective building material—mainly composed of clinker—that meets all applicable chemical and physical requirements and is widely used in all construction segments: residential, commercial, industrial, and public infrastructure.
Cement is a fine binding powder that is never used alone, but is a component of both concrete and mortar, as well as stucco, tile grout, and thinset adhesive. Mortar is composed of cement, fine sands and lime it is used a binding material when building with brick, block, and stone.
