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.
