portland slag cement- Its Really better, Try it

Suitable for road, ports, tunnels and river portland slag cement is used all across for its ecological value. With the rising consciousness with respect to diminishing natural resources, the construction industry has shifted their focus to using eco friendly material than harnessing core natural resources. Technology and technical knowledge has enable land contractors to make use of blast furnace slag from steel, which is undoubtedly effective in controlling pollution and making environment safer, and secure. Today maximum infrastructure services are completed using slag cement instead of ordinary Portland cement. Slag cement is known as ‘greener cement’ as it is nature permissive.

Core benefits of using slag cement
·         Now slag cement is ordained to end in disposal but today it is deemed as one of the finest value-added product from a blast furnace slag. Slag cement comes with two benefits one it lessens the load on landfills second it diminishes air emissions at steel plants by involving the core granulation procedure. You can make use of slag cement in concrete thus lessening the ecological impact of concrete.
·         Now while enumerating other benefits, this portland slag cement will effectively be reducing greenhouse gas emissions by lessening down one ton of carbon-di-oxide, as this slag cement needs less energy so it reduces energy consumption quite effectively. It again reduces the quantity of virgin materials which are dug out to make concrete.
·         Making the construction lighter in color, this material reduces the urban heat island effect. so this material is wonderful for exposed concretes and pavements. Even the Environmental Protection Agency acknowledges the environmental advantages of using the slag cement in concrete. Even the Resource Conservation Recovery Act (RCRA) has recognized this product as the recovered product
 What is slag cement used for
Slag cement is extensively used in exposed concrete as one of the separated cementitious component, often it is used as one of integral component while blending cement. Working together with portland cement, slag cement works synergistically to enhance strength, potency thus reducing permeability, enhancing resistance to chemical attack and restraining rebar deterioration. Slag cement is exploited  in literally all concrete applications, while making concrete pavements, foundations, structures, dams and retaining walls, mass concrete applications, for pre cast and pretressed concrete, pipe and block, when concrete is exposed to the harsh elements of nature for example wastewater treatment and marine applications. They are high strength and high performing concrete and provides years long service to bridges or high-rise structures. Slag cement can be  used in non-concrete application for example soil-cement and perilous waste solidification.
Why you should use PSC
The intrinsic chemistry offers manifold benefits over ordinary cement and the most important advantage is, it comes within budget. Although it is identified as one of the finest eco friendly items of all but builders today make use of this material for their Ultimate compressive strength, Minimised shrinkage cracks, Low risk of cracking, Better compatibility with all types of admixtures, Improved workability, Excellent resistance to Chloride & Sulphate attacks, Superior finish, Better resistance against alkali-silica reaction and Ease of pumping.

Types of Portland slag cement
To peep into the preparation of cement, it is a material, where limestone is heated together with clay in a kiln at 1450 degrees. The result is clinker where other materials are mixed, depending upon this mixture, cements are differentiated in types and categories. The more heat is provided the more the cement gets harder. There are varying sorts of cements available in market such as Rapid hardening cements, Portland cements and Non Portland cements, so right before you initiate your Infrastructure services,  you need to learn about the elements properly.
Below details of Portland Cement is given
However among all varieties, Portland cement is one of the commonplace cements which is basically used in construction works all around the world. This sort of cement used to be identified as ordinary Portland cement where clinker is mixed with gypsum. This cement is known to be used in building the foundation of the construction. While making the foundation cement is mixed with sand, gravel together with water. This cement is flexible and can be molded in any shape; the moment it hardens, it builds the bottom of any construction. No matter how concrete the base is the base is not  very sustainable. The Cement is durable and versatile, available in white and grey color.

Few Portland cement types:
White Cement:  this is a type of cement where into the cement white clay kaolin and white chalk are scattered.  The content also holds little amounts of iron oxide and manganese oxide. Due to the presence of white chalk, the white cement appears white in color. When there is a need to prepare white or off white colored concrete, this sort of cement is used. Buildings which are needed to have white or off white external shade, this cement is chosen. This variety is widely available in market.
Masonry Cement: Limestone and hydrated lime these materials are mixed with Portland cement. For making masonry mortars such as plastering, brick lying, rendering this cement type is optimally used. When mixture is suitably prepared, when the cement is having sufficient amount of minerals, required amount of air entraining plasticizers are blended to generate air bubbles. Typically, varying sorts of sands and sufficient water is mixed to make the mortars more functional and consistent. These mortars never get frozen and thaw resistant in damp and newly hardened situation.
Expansive Cements:  expansive cement is basically the mixture of calcium sulfoaluminate clinkers, Portland slag cement  and some amount of gypsum. This cement is basically meant for compensation of concretes which are known for shrinking when they dry. This mixture is used for either the compensation of the contraction of the concrete or sometimes enhancing the volume of the concrete the moment it is arranged.
Silica Fumes Portland Cement:  as the name suggests the mixture contains the silica fumes along with Portland cement. These cements are known for unconditional strength and potency. These cements are wonderfully durable and hard.

Blast Furnace Portland Cement:
70% granulated blast furnace slag is there in this mixture and along with some gypsum, Portland cement is mixed. This mixture is having high strength and the sulfate resistance is increased in amount for extra strength.
