How cement is made and used as an important material for construction

LinkedIn0 Cement is very important building material among other in construction industry. Cement has replaced all other building materials, like clay and lime, which ruled high for hundreds of years, in construction from last century.

How cement is made and used as an important material for construction


Portland cement Portland cement is by far the most common type of cement in general use around the world. Portland cement is a basic ingredient of concretemortarand most non-specialty grout.

The most common use for Portland cement is to make concrete. Concrete is a composite material made of aggregate gravel and sandcement, and water. As a construction material, concrete can be cast in almost any shape, and once it hardens, can be a structural load bearing element.

Portland cement may be grey or white. Portland cement blends[ edit ] Portland cement blends are often available as inter-ground mixtures from cement producers, but similar formulations are often also mixed from the ground components at the concrete mixing plant.

All compositions produce high ultimate strength, but as slag content is increased, early strength is reduced, while sulfate resistance increases and heat evolution diminishes. Used as an economic alternative to Portland sulfate-resisting and low-heat cements. The fly ash is pozzolanicso that ultimate strength is maintained.

Because fly ash addition allows a lower concrete water content, early strength can also be maintained. Where good quality cheap fly ash is available, this can be an economic alternative to ordinary Portland cement. In countries where volcanic ashes are available e.

The maximum replacement ratios are generally defined as for Portland-fly ash cement. Portland silica fume cement.

However, silica fume is more usually added to Portland cement at the concrete mixer. They are usually complex proprietary formulations containing Portland clinker and a number of other ingredients that may include limestone, hydrated lime, air entrainers, retarders, waterproofers and coloring agents.

They are formulated to yield workable mortars that allow rapid and consistent masonry work. These are designed to produce a controlled bond with masonry blocks. Expansive cements contain, in addition to Portland clinker, expansive clinkers usually sulfoaluminate clinkersand are designed to offset the effects of drying shrinkage normally encountered in hydraulic cements.

White blended cements may be made using white clinker containing little or no iron and white supplementary materials such as high-purity metakaolin.

Colored cements serve decorative purposes. Some standards allow the addition of pigments to produce colored Portland cement. Very finely ground cements are cement mixed with sand or with slag or other pozzolan type minerals that are extremely finely ground together.

These are the cements the Romans used, and are present in surviving Roman structures like the Pantheon in Rome. They develop strength slowly, but their ultimate strength can be very high.

Cement - Wikipedia

The hydration products that produce strength are essentially the same as those in Portland cement. Slag-lime cements— ground granulated blast-furnace slag is not hydraulic on its own, but is "activated" by addition of alkalis, most economically using lime.

They are similar to pozzolan lime cements in their properties.German Plant Experience is a specialist company involved in manufacturing of Concrete Batching Plants, Cement Silos, Cement Terminals, Pugmills, Concrete Pipe and Manhole Machines and Asphalt Plants used in industries around the and its associated companies in Germany, Dubai, Italy and Australia have established more than such plants in different countries producing Concrete and.

CEMENT - An introduction to the World’s most important building material

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.

Popular Posts Used in the majority of buildings, bridges, tunnels and dams for its strength Gains strength over time Not weakened by moisture, mould or pests Concrete structures can withstand natural disasters such as earthquakes and hurricanes Roman buildings over 1, years old such as the Coliseum are living examples of the strength and durability of concrete Versatility Concrete is used in buildings, bridges, dams, tunnels, sewerage systems pavements, runways and even roads Low Maintenance Concrete, being inert, compact and non-porous, does not attract mould or lose its key properties over time Affordability Compared to other comparable building materials e. Very little cement and concrete is traded and transported internationally This saves significantly on transport emissions of CO2 that would otherwise occur Albedo Effect The high "albedo" reflective qualities of concrete used in pavements and building walls means more light is reflected and less heat is absorbed, resulting in cooler temperatures This reduces the "urban heat island" effect prevalent in cities today, and hence reduces energy use for e.

Applications of cement Etymology[ edit ] The word concrete comes from the Latin word "concretus" meaning compact or condensed[7] the perfect passive participle of "concrescere", from "con-" together and "crescere" to grow. Prehistory[ edit ] Small-scale production of concrete-like materials dates to BC, pioneered by the Nabataea traders or Bedouinswho occupied and controlled a series of oases and developed a small empire in the regions of southern Syria and northern Jordan.

Building material is any material which is used for a construction purpose. Many naturally occurring substances, such as clay, sand, wood and rocks, even Types of Building Materials Used in Construction Cement bonded composites are an important class of building materials.

These products are made of hydrated cement paste that binds . Find the best cement price in Bangalore Cement is one of the most important materials required for any construction project. It is the material that binds together the entire structure and determines the strength, stability, and durability of the building.

Installing fiber cement siding (FCS)—such as HardiePlank®—is easier than you might think, though there are some important differences from traditional wood siding. Installation instructions may vary depending on the manufacturer, and check with your local building inspector for any code requirements.
