The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water.As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element.
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.
Portland Pozzolana Cement also commonly known as PPC cement. These types of cement are manufactured by using pozzolanic materials as one of the main ingredient. The percentage of pozzolanic material used in the preparation should be between 10 to 30. If the percentage is exceeded, the strength of cement is reduced.
Pozzolana cement (IS: 1489-1991) : The pozzolana is a volcanic powder. It is found in Italy near vesuvius. It resembles surkhi which is prepared by burning bricks made from ordinary soils. It can also be processed from shales and certain types of
Composition and manufacturing of pozzolana Portland cement (PPC): Pozzolana Portland cement is manufactured by grinding Portland cement clinker and pozzolana (usually fly ash 10 to 30 % by mass of PPC) or by intimately and uniformly Portland cement and fine pozzolana. As per the latest amendment the proportion of pozzolana may vary from 15 to
How Cement Is Made Portland Cement Association. 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
Portland Pozzolana Cement (PPC) PPC Cement has a greater degree of fineness, impermeable and corrosion-resistant quality that makes the concrete denser resulting in long-lasting structures. Since it has the high impermeable quality it is used in mass concreting work instead of ordinary cement due to adverse soil conditions. Manufactured
Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or mixing the Ground Granulated Blast Furnace Slag (GGBS) with Ordinary Portland Cement by means of mechanical blenders. It is created with a blend of 45- 50% slag, 45% & 50% clinker, and 3-5% gypsum.
Jul 30, 2016· Cement is made by heating limestone (calcium carbonate) with small quantities of other materials (such as clay) to 1450°C in a kiln. The resulting hard substance, called 'clinker', is then ground with a small amount of gypsum into a powder to make...
The history of cement goes back into Roman Empire. The modern day cement. That is Portland cement was first produced by a British stone mason, Joseph Aspdin in 1824, who cooked cement in his kitchen. He heated a mixture of limestone and clay powder in his kitchen, and grind the mixture into powder creating cement, that hardens when mixed with
Portland cement can be made by following two different processes a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. 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
Sand cement, and; Air-entraining Portland cement. Ordinary Portland Cement . This cement is the basic Portland cement and is best suited for use in general concrete construction where there is no exposure to sulphates in the soil or in groundwater.

Cement is the substance which holds concrete together, which means that it is extremely widely used in our society. It has been manufactured in New Zealand for more than 100 years, and during this century production has increased one hundred-fold. Portland cement (the only type of cement in common use today) is manufactured in a four step process.
Oct 24, 2009· Pozzolanic cement is a cement which consists of pozzolanic materials like fly ash, volcanic ash, pumicite,etc., Contains pozzolanic materials of 10
Portland pozzolana cement (PPC) has following advantages when concrete is in its fresh state. 1. Workability. Portland pozzolana cement has spherical cement particles and they have higher fineness value. Due to the spherical shape concrete move more freely and more fineness of particles allows better filling of the pores.
As per IS:1489 (Part 1), the Fly-ash constituent shall not be less than 15% and not more than 35% by mass of Portland Pozzolana Cement. PPC is an eco-friendly product as it is manufactured using fly-ash, a by-product from the thermal power plants. It provides better resistance to alkali-silica reaction.
