Opc concrete what is

They can be reliably utilized in the construction of marine structures, masonry mortars and plastering, hydraulic structures. Besides, they are popularly used in mass concreting works, such as dykes, sewage pipes, dams, etc. However, OPC is the most commonly used cement worldwide. The cost of production is not expensive making it the sought after cement in the building industry.

They are widely used for the construction of high-rise buildings, roads, dams, bridges, flyovers. Also, OPC is used for making grouts and mortars. OPC is ideal for the construction of residential and industrial complexes. PPC VS. OPC Cement. Your email address will not be published. Post your Requirement. Quantity: Select Unit Sq. Foot Sq. Where do you need these?

It has high heat of hydration making it unfavorable for mass concreting. The hydration process is slower than OPC resulting low heat of hydration. Therefore, it is suitable for mass concreting.

The presence of sulphates, alkalies, chlorides, etc. The heat of hydration is the heat generated when water and cement react. Whereas in the case of PPC, the hydration process takes a long time and produces less heat during the hydration process. Hence it is ideal for mass concreting.

On the other hand, the final setting time of PPC is minutes that is 25 days PPC cement prolongs the setting time of concrete and hence it helps in better finishing of concrete. Whereas the finance of PPC is at least square meters per kg which are higher than OPC hence it is difficult to handle but it is not a major thing.

Permeability is the quality of any substance to measure how much liquid or water can pass through them due to the absence of pozzolanic material ordinary Portland cement is highly permeable to the water. On the other hand, pozzolana cement is less permeable and it is suitable for a structure Such as bridge piers or a Foundation , where the waterproof structure is recommended.

OPC requires a minimum curing period of 7 days. When OPC is exposed to hot and dry weather conditions the minimum curing period required shall not be less than 10 days. The heat of hydration is the major need for the curing of concrete, this drives the choice of the cement. This type of cement is manufactured as a powder by mixing limestone and other raw materials which consist of argillaceous, calcareous and gypsum.

It is preferred in places where there is a need for fast construction and setting time. These grades imply the maximum strength of the particular cement after 28 days. Where OPC is used- OPC is widely used for the construction of high-rise buildings, roads, dams, bridges, flyovers where high strength and fast setting is required. Pozzolana is an artificial or natural material that has silica in it in a reactive form.
