In today’s world, buying cement online has become increasingly popular among developers and other experts, since it helps them in procuring fresh supplies along with relevant product details right from their site office.
What Is OPC Cement?
Ordinary Portland Cement, also called OPC, is one of the oldest forms of cement that has been used in construction worldwide. This cement is produced through grinding limestone and other materials into a powdered form. OPC cement is classified based on its compressive strength; among the different types, OPC 53 is the most preferred because of its ability to support large loads. When planning to buy Cement Online, people prefer OPC 53 because they expect their structures to withstand great pressures.
Fast Compressive Strength
What sets OPC apart from other cements is that it gains great compressive strength very quickly after being cast. OPC is considered the ideal material for any fast-paced project, especially when one needs to dismantle formwork in order to start working on the second storey of the structure. If this is what you require, then you should buy Cement Online and consider OPC 53 for your RCC work.
OPC Is Perfect For Heavy Duty Construction
Being a high early strength cement, OPC is widely used in beam, column, and slab casting. It is designed for construction work that needs strong cement for load-bearing buildings, skyscrapers, and industrial plants. When construction companies buy Cement Online for building bridges and flyovers, OPC becomes their choice because of its reliable and strong
construction properties. In case you have an urgent project with a short construction period and require a strong base, OPC is your best bet.
Introduction to PPC Cement
Portland Pozzolana Cement, often abbreviated as PPC, is a kind of cement that is produced by combining OPC clinker with certain amounts of pozzolans, mostly fly ash. Besides adding value in terms of sustainability, the fly ash in PPC makes it durable. For instance, many environmentally friendly constructors nowadays tend to buy Cement Online and prefer using PPC due to its several advantages.
Superior Workability and Finishing Quality
In addition to being sustainable, PPC cement is renowned for having excellent workability properties. This is due to the role played by the fine powder of the fly ash, which serves as lubricant in the cement mixture. As a result, the surface becomes very smooth, and hence why it is advisable to purchase this kind of cement when intending to do finishing works.
Moisture Resistance and Durability
Among the major strengths of PPC is that it has the capability to resist chemical reactions and moisture. Its heat of hydration is lower than that of OPC, thus making it highly unlikely for cracks to develop. If you are constructing in a moist environment or coastal location, then it would be wise to purchase Cement Online and use PPC to guard your construction from sulphate and chloride reactions. With age, PPC will continue to get stronger, overtaking OPC’s endurance levels.
PPC vs OPC – Major Differences
It is highly recommended that one compare these two types of cement based on a number of parameters before you buy Cement Online. Below is a comparison between these cements based on a few parameters:
Development of Strength: OPC acquires strength rapidly due to early strength; on the contrary, PPC acquires strength at a slower rate but keeps on getting harder over a long period of time.
Setting Time: OPC sets much faster when compared to PPC. Those who want their projects to be completed quickly can opt to buy Cement Online and then use OPC for construction purposes.
Heat of Hydration: OPC releases too much heat when chemically reacting with water. On the other hand, PPC releases heat in small amounts.
Resistance to Cracking: PPC is quite resistant to cracking owing to the lower heat of hydration as well as fly ash content.
Affordability: In terms of cost-effectiveness, PPC is better when compared to OPC, as the latter contains fly ash. It means that those buying Cement Online can save a considerable amount of money.
Eco-friendliness: PPC cement is called a green cement because it causes no harm to the environment.
What Kind of Cement Should Be Used on a Residential Project?
In a normal residential building project, it would make sense to use both kinds of cement. However, when it comes to durability and value for money, PPC cement usually turns out to be a much better choice.
Why PPC Cement Works for Homes
A homeowner who decides to buy Cement Online for his project will find PPC much more suitable for bricks, floors, and plaster work on the exterior surface. Since it is waterproof, it will help keep the walls dry for many years. Moreover, the slow-setting time does not become an issue because residential projects do not have such stringent deadlines as skyscrapers.
When to Consider OPC Cement for a Residential Project
If the project involves pouring the structure of the building, the foundation, the pillars, and the roof slab,b then it makes sense to purchase Cement Online and use OPC 53 cement.
What Cement Should Be Purchased For Commercial And Big Construction Projects?
Commercial construction projects are significantly weightier compared to other constructions. The choice to purchase Cement Online for such constructions depends on the design offered by the civil engineer.
In road, bridge, and dam construction projects, the use of OPC cement is compulsory in the construction of RCC structures owing to its strong compressive strength. But in the non-RCC section of such big projects, where one will need to finish an industrial floor or do masonry work in a huge office building, the developer chooses PPC cement and purchases Cement Online in bulk.
Comparison of Costs for PPC & OPC
Budget is a crucial aspect in any construction project. Buying Cement Online, you will notice that PPC is usually cheaper by 5% to 10%. This variation in price arises from the use of fly ash which is one of the major ingredients in PPC and an industrial waste product that is easier and cheaper to source compared to the pure clinker in OPC.
Contractors who undertake big projects have the option of buying Cement Online to make bulk purchases. The advantage of using PPC in masonry and plastering is that it helps the contractors to save some cash although the quality of work remains unaffected. On the other hand, while the OPC is a little expensive, it may help in saving money through time efficiency.
Durability and Long-Term Performance
The lifespan of an object is its true test. While OPC gives you quick strength, PPC turns out to be the superior choice in the span of many years. The structure of PPC is denser than that of OPC, making it impossible for the ingress of harmful substances and water into the cement. This explains why engineers opt for Cement Online in cases where the construction project involves hydraulic structures and buildings located in areas of high rainfall.
Additionally, since the heat of hydration of PPC is low, there are no internal stresses in the concrete. As a result, you will find very few cracks on the wall. To build a structure that lasts for many generations without repairs, you must choose to buy Cement Online, and in this regard, PPC is the best alternative.
When Should You Opt for OPC?
You must consider purchasing OPC grade 53 at Cement Online if your project meets one of the following criteria:
When You Are in a Rush: When you have an urgent project timeline and want to complete the work as soon as possible.
Load-Bearing Structures: In cases where you plan to cast load-bearing structures such as pillars, slabs, and foundation work in tall buildings.
Precast Concrete: When you are working on making pre-cast concrete elements, such as pipes and blocks, which will require transportation soon after casting.
Cold Conditions: OPC works better in cold conditions than other types of cement.
Contractors feel that most of their projects start off by buying Cement Online using OPC grades.
