PCC is the mixture of cement, fine aggregate sand , and coarse aggregate Read more. Plastering is a method of applying a thin coat or covering of cement mortar on the surface of the brick masonry wall or c Thus to reduce the building making cost, PPC should be adopted.
Portland pozzolana cement is Better resistant to sulfate attacks. Thus PPC is used in underwater construction where water has some amount of sulfur quantity. Its setting time is higher than OPC. OPC cement gives high compressive strength at early stages and at 28 days. OPC cement also has increased workability and higher strength at later stages.
Hence, it has early strength and also has cost saving advantages can generally used for the construction of concrete slab. OPC cement can also be recommended for the construction of columns, beams, etc.
They are commonly used for small residential construction. PPC is recommended for brick masonry, plastering, tiling and waterproofing works. It has slower rate of heat of hydration. PPC is prone to less cracks and reduced shrinkage and also gives better workability and finishing. Thus, PPC is only used where the possibilities of sulphate attack is higher as it is said to be the good sulphate resistor.
OPC is the most commonly used cement in industrial and large construction, PPC is most commonly used for small residential constructions. PPC is used where possibilities of sulphate attack is higher as it has good sulphate resistance compared to OPC. Also pozzolana Portland cement is cheaper than ordinary Portland cement. OPC cement hardens faster than PPC, has higher heat of hydration and thus it requires more care in curing.

Due to its excellent corrosion resistance, particularly from salt water, it is widely used in coastal regions, sewage disposal, and water treatment plants. White Cement: This cement is used in architectural and decorative designs, it is also used to fill gaps in wall tiles, ceramic bathroom fixtures.
The manufacturing process of white cement is different and more complicated when compared to ordinary Portland cement. OPC Benefits Today, we know that grape seed extract contains oligomeric proanthocyanidin OPC , an antioxidant that is believed to improve certain health conditions. Like this post?

Inert materials like dolomite lime-stones, gypsum, air-entraining agent are mixed with clinkers of portland cement. Concrete is workable, possess, fattiness, cohesiveness, plasticity. It tetains mixing water than comes in contract with dry bricks. Not suitable for works other than masonary work. It should capable of being pumped for 3 hours under high pressure and temperature, It sets slowly and hardens quickly.
Volcanic ash, pumice, or powered burnt brick can be used as pozzolana Produces less heat of hydration resists sulphate action, developes strength slowly, imparts water githtness, more workability and plastically, possess high strength, cheap. Mass concrete construction in costal areas sewage works contruction below ground. Sets in 5 minutes and gets hard in 30 minutes. Fine grinding after adding a small percentage of aluminum sulfate. The percentage of gypsum and retarders are reduced.
High strength is achieved earlier due to a higher degree of fineness in grinding, clinkering at high temperature 7 days, and 28 days strength of ordinary concrete is obtained in 3 days and 7 days only Not suitable for mass concrete. Concrete in cold weather climate, early removal of forms, speed in construction, early use of structure. Mir is finely ground. Low heat of hydration hence suitable for mass concrete. Resistive to chemical attack cement expands when used underwater and shrinks when cured in air.
Forms good bond with set concrete. Suitable for all purpose mass concrete places where chemical attck is suspected. Calcium sterate. Aluminium sterate and gypsum treated tannic acid are added to ordinary portland cement while grinding.
