How to use cement when building a house? What you need to know about cement.
In a changing world, cement has become an integral part of every physical structure. It is not possible to think of building physical infrastructure without the use of cement. After the 2072 BS earthquake, the use of cement increased in remote villages. Cement is a ‘chemical blender’. Cement is used to bind sandy, ballast sand to sand. There are two types of cement, usually gray and white.
Different types of gray cement have been used in the world market. However, in the case of Nepal, three types of gray cement are being used, namely OPC, PPC and PSC.
The most commonly used cement OPC is PPC. If OPC is being used in Pillar, Bimardhala, then PPC is being used for plaster casting.
What is opc?
Ordinary Portland Cement (OPC) is a cement made of ordinary limestone. Limestone is measured at 14 ग्री C and mixed with various substances to make a clicker. The amount of clinker used in OPC is increased. OPC is made by mixing a maximum of five percent gypsum in clinker. As the amount of OPC clinker increases, it gets set quickly.
OPC has three grades, 33 grades, 43 grades and 53 grades. Ordinary OPC of 33 grades. The highest grade of 43 grade cement is being used in the construction of structures. 43 grade cement is used in the construction of buildings. This is not to say that 43 grade cement should not be used in large scale construction in Nepal, most of the 53 grade cement has been given more priority.
What is PPC?
Portland Pozzolana Cement (PPC) is made from coal-fired ash (dust) (Pujolona) maclinker. 70 percent clinker, 25 percent pujolonar and 5 percent gypsum are used in making this cement. Due to the small amount of clinker, it takes a long time to set up PPC.
However, it is not a good quality cement. However, PPC is being used in Nepal for most of the time. Plaster is not used. This is not to say that structures cannot be built using PPC cement. PPC can be used if the structure is designed to be flexible.
Portland Slag Cement (PSC) has just come into operation. Hard plaster is being used in both.
Which structure to use?
All cement has its own characteristics. OPCs are set faster than PPCs when the amount of clinker is higher.
In Nepal, OPC is widely used for making pillars. OPC solution is used when working on ballast, sandstone poles, PPC is used when working with sand only. If the construction needs to be completed soon, OPC is used. Due to the rapid growth of OPC, the use of MICs in large projects is considered appropriate. If it takes more time to set up PPC cement, it will take less time to set up the structure of OPC. OPC cement is also called ‘fast setting’ cement.
This is not to say that PPC will not be demolished. Buildings are being demolished using PPC cement.
Some people know that PPC cement is made of slope, while others are made of PPC cement in consultation with engineers.
All cement Has its own characteristics. OPCs are set faster than PPCs when the amount of clinker is higher. In Nepal, OPC is widely used for making pillars.
According to the engineer’s advice, the OPC should be kept in water for some time after the construction of the leadpillar pillar. According to the engineer’s advice, after the construction of OPC ledge pillar, water should be kept in the water tank for some time so that the slope does not burst due to heat stroke. Generally, the quality of OPC quality PPC cement does not differ significantly.
The type of structure you are trying to build, the engineer has designed the structure, different grades of cement can be used accordingly. The biggest thing is the quality consistency of the cement you use. However, when you buy cement from any company, it should be of high quality. The engineer has already decided which grade of cement to use when designing the structure. Generally, 53 or 43 grade cement is sought for tall buildings. However, the construction of a building does not necessarily require a grade of cement, the use of a grade of cement according to the design of the building strengthens the structure. The design of the building depends on the strength of the building you are going to build, the grade of cement used, the strength of the gravel, sand, cement, chemical water and the strength of the building.
Differences between graders
Some consumers may be confused between the cement grade Nepal quality (NS) mark.
Cement grade is the load-bearing capacity. This is the strength of cement. In Nepal, OPC cement is available in 33rd grade, 43rd grade and 53rd grade. Different grades of cement are used according to the design of the structure. And, of course, yes.
53 grade cement is also being used in the infrastructure of big buildings.
The department gives Nepal Quality Level (NS) mark by evaluating the study that the cement quality produced by the industry is not up to standard.
The department periodically tests the samples of cement from the industry and the market. Consumers may be shocked when the department buys the quality mark provided by the department. Cement is not officially sold or distributed in Nepal for quality consideration.
How long can it be used?
Cement is said to be stored properly, which determines its usefulness. A well-stored cement can be used for up to three months, depending on the production date.
Cement storage should be done with caution. Cement does not have to be smooth. Cement does not work well. Cement does not work well. Does the lumpy cement not work well. If it gets wet, the cement can deteriorate in a day.
However, the cement can be used for up to three months in a dry enclosed room, covered with a water-repellent coating.
Care should be taken while making the solution
This is the most important aspect. Cement is just a chemical blender. You have to make a solution according to your structure. Water has a very big role in making a solution of cement, ballast, sand. You should not use dirty water.
Engineers have already decided which grade of cement to use when designing the structure. Usually 53 or 43 grade cement is sought for a tall building. However, the construction of a building does not necessarily require a grade of cement, the use of a grade of cement according to the design of the building strengthens the structure. Engineers or experienced mechanics should make the solution only by removing the water-cement corrosion. Even if there is too much water in the solution, it will not work well. When making the solution, the ballast, sand and water should be clean. Only the slope is strong. Should not be mixed with sand,
Cement may not work properly. If sand, water, cement and cement are mixed, the construction will be strengthened.
You bought the cement well. You bought the ballast sand according to the quality criteria. working man does not make the solution well, no matter how good the cement, ballast or sand is, it will not be strong. The man making the solution should be experienced. After making the solution, it should be eaten well.
General confusion about cement
Some consumers may be confused about cement. Dozens of new brands of cement are available in the market now. We have to use cement according to the design of the structure as per the advice of engineer or consultant. However, some consumers are told, “Cement is not worth anything!” It should be understood that the cement may not be of the same quality. The cement should be used as required during construction.
Which cement is being used more in the market? Which cement users are interested in? What kind of infrastructure is being built by Kansi Cement?
You can look at it from different angles.
First of all, you have to see if the cement is made according to the quality standards. The engineer knows a lot about the contractor company.
Some people may think that a little bit of cement will make the house stronger. This is just an illusion. If the cement is too much, the house will not be strong.
Cement should not be overcooked, nor should it be overcooked. Only quality mix with cement, water, ballast and sand can be used for quality construction. If the mixing is good, no matter what the brand or grade of cement is, the structure will not be strong.
Cement is one of the characteristics of Nunn, when it is low, when it is high.
If the design of the building is suitable for 43 grade cement, but using 53 grade cement, it does not mean that it will be strong. The quantity of cement in the solution should be fine. If the ratio is less than the cement used, the construction should not be strong. Therefore, in order to make the vegetables palatable, it should be kept in the right way, and in the construction work, the quantity of cement should be used as per the technical requirements.
Consumers should pay attention when buying cement
When was the first cement made when buying cement? You have to look at the production date. Cement should be checked to see if it is cracked.
When buying cement, you should not look at the quality mark of Nepal. Cement that has been in production for more than three months should not be purchased.
