The post How many rods are in 8 mm bundle? | Number of TMT rods in a bundle appeared first on Construction materials online store, Bangalore.

]]>
TMT Diameter (Approx weight/ Rod)Number of Rods in a bundle
8 mm (1 Rod = 4.7 Kg)10 Rods
10 mm (1 Rod = 7.4 Kg)7 Rods
12 mm (1 Rod = 10.6 Kg)5 Rods
16 mm (1 Rod = 18.9 Kg)3 Rods
20 mm (1 Rod = 29.6 Kg)2 Rods
25 mm (1 Rod = 46.3 Kg)1 Rod
32 mm (1 Rod = 75.7 Kg)1 Rod
Note: Weight mentioned here is of approximate value. Weight also varies from brand to brand.

How to calculate the weight of one bundle?

You can calculate the weight of one bundle by multiplying the rod weight with the number of rods i.e., Weight of a TMT Rod x Number of rods in a bundle = Weight of the bundle.

Example: One rod of 8mm TMT steel weighs 4.7 kgs, and the number of rods in an 8mm bundle is 10, therefore 4.7 kgs multiplied with 10 gives you 47 Kgs, which is the bundle weight.

]]> Ordinary Portland cement (OPC) and Portland Pozzolana cement (PPC) are two of the cement types that are used for many construction purposes.

However, there are few basic differences between OPC and PPC Grade cement:

OPC Grade CementPPC Grade cement
Full form:Ordinary Portland CementPortland Pozzolana Cement
Grades:33 Grade, 43 Grade, 53 GradeNone (Only PPC Grade)
Constituents:Limestone, Gypsum, Clinkers, SilicaPozzolanic materials (Volcanic ash, Fly ash), OPC, Gypsum
Used for:General residential/ commercial construction worksMarine constructions, Buildings near seashores, Dams, Industrial structures, etc
(Due to its high resistance towards sulphate attacks)
Setting Time:Fast setting
(Achieves 43/53 Mpa by 28 days)		Slow setting
(Achieves 33 Mpa by 28 days)
Concrete Strength:Greater strength during the initial days of curing, due to faster setting timeInitially, the strength is not equivalent to OPC grade. However, it gains more strength than OPC with the passage of time.
Price:OPC cement costs more than PPC PPC cement costs less than OPC

Hope our article, difference between Ordinary Portland cement (OPC) and Pozzolana Portland cement (PPC) as helped you in choosing the right cement type for your construction.

The post How Covid-19 has affected the construction industry in India? appeared first on Construction materials online store, Bangalore.

]]> The Global as well as the Indian economy has taken a big hit due to the impact of Covid-19 since all the economy leading industries has paused their operations or reduced their productions.

Construction industry, a leading contributor to the Indian economy (8.2% GDP) has been severely affected by this pandemic.

Cement and steel being the two core sectors of the economy, have also put their operations on halt due to the lockdown, thus leading to supply chain disruptions.

Shortage of labors:

The construction industry alone employs 12% of the nation’s population and requires a larger workforce with both skilled and unskilled laborers.

And more than 30% of the labors have migrated back to their natives due to the fear of pandemic.

All construction activities including private as well as public works have been bought to a halt after the Government imposed the lockdown, affecting the livelihood of daily wage workers.

Impact on large scale projects:

No supply of materials and shortage of workers has highly affected the private builders & developers, thus leading to the delay of project completion and conversely affecting the timely delivery of the project to the customers.

The public infrastructure projects which acted as economical boosters have also been paused by the government.

Financial implications:

The construction industry & businesses related to this sector have a high cash transaction ratio when compared with any other industry/ sector. This factor will slow down the overall payment process within the industry.

Any construction work undertaken now will be slow processed and can push up the procurement costs.

Future of construction industry:

With the Government planning to exit the lockdown strategically, the construction industry will be revived slowly. However, the presence of Covid-19 will continue to haunt the sector.

We might see some new policies by the government regarding the safety of the workers, new guidelines for minimal labor requirements, on-site facilities for them, and the use of technology for detection & further prevention of the disease.

The government can also relax the interest terms provided to the individual homeowners. The builders/ developers might seek some financial relaxations (penalties) and extensions to address the delay of their projects.
