The first Portland cement manufactured in South Africa was in 1892 by De Eerste Zement Fabrieken Beperkt, which became Pretoria Portland Cement, or PPC (PPC, 2010). Since then there has been a steady growth (Akindahunsi, 2011) in the quantity of cement produced in direct relation to the country's demand (PPC, 2007).

Grinding the clinker with gypsum: The cement clinker is usually ground in a ball mill to form fine powder. A small amount of gypsum (5%) is used in this grinding process to control the setting properties of concrete when mixed with water. The end product of this process is called "Portland Cement".
The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C.
A step shall be made if the excavation is more than 1.5 m to prevent soil collapse. Pile head cutting: Concrete will be removed up to cut off level. If concrete under the cut off level is unsound. It shall be removed, and the pile will be repaired. Pile must be free from cracks and unsound concrete. Blinding concrete: after completion o…
The basic ingredients of both the dry and wet processes are the same. By mass, lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main component, often cement plants are located near limestone quarries.
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.
The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.

4. Add small stones to the mixture to strengthen the concrete, mixing the final concrete product with a hoe to completely encompass the stones. 5. Pour the concrete into place, tamping the concrete down with a wooden tool to make sure the zero-slump mixture completely fills the form you're placing it into.
"Both in Germany and in France the production of Portland Cement began in 1850." The first Spanish Portland cement was made in Asturias. Uses of Portland Cement. Portland Cement can be used for all kinds of constructions as it is compatible with practically all conventional construction materials. It's a very versatile and high-quality ...
Portland cement concrete, in particular high strength concrete, is highly susceptible to spalling in a fire [37]. High strength concretes are generally defined as concretes with compressive strengths above 50 MPa, and are widely used in construction since the late 1980s. spalling of high strength concrete, first reported in 1993 [ 37 ], is an ...
