What are aerated blocks used for?

Aerated blocks are a type of innovative concrete blocks that contain more than 80 percent air. They are also called autoclaved aerated concrete (AAC). Aerated concrete is a group of materials you would describe as lightweight concrete. Previously, lightweight concrete is an arbitrary term; however, aerated concrete blocks have numerous advantages, such as light, better insulation (sound and light), and stronger than conventional blocks.

Manufacturing of AAC Blocks

To make an aerated block, air is introduced into its composition; furthermore, there are three ways to bring in air in its compositions.

  • By using a porous aggregate, which retains air within the aggregate itself
  • Through a single-size aggregate, thereby leaving interstitial air voids
  • By directly introducing air or other gas into cement slurry in a manner that whenever the cement sets, it forms a uniform cellular concrete.

Famously, AAC is described as a cement paste that has gas bubbles introduced inside them. However, aerated concrete contains a substantial amount of siliceous materials in the form of silica flour, ground burnt shale, and pulverized-fuel ash.

AAC Block price

Cost is an important issue about aerated blocks. Most times, people consider a lot of things besides looking at aac block price. They focus on logistics, shipping costs, and easier means to transport. However, if your building is close to a facility, you would benefit as the cost will reduce.

Properties of Aerated Concrete Blocks

Density

Aerated blocks have a low density, which ranges between 25-50lb. The lighter aerated concrete blocks are used for insulation purposes but have indifferent strength. Nevertheless, the heavier grade of aac blocks has higher straight with low insulation value. The density range for the heavier grade ranges from 40 to 50 lb. per cubic feet.

Compressive Strength

The assessment of declared strength values from several sources is considered difficult due to different testing methods, shapes, and samples. The size and shape are significant because they can affect the outcome of the block by 30 percent.

Modulus of Elasticity

Aerated blocks have a low modulus of elasticity compared to conventional concrete.

Benefits of Using Aerated Blocks

Are you missing the benefits of using autoclave aerated concretes? AAC blocks are important building tools that have been in existence since 1920. If you think it is not worth using today, here are a few reasons to change your perception of aac blocks.

  • Faster construction – AAC blocks minimize construction times because the blocs are bigger with fewer joints than non-autoclaved aerated concrete blocks. Because of this, they are easier to maneuver, which leads to faster completion when working
  • Durability – These concrete blocks are strong and outlast ordinary blocks. Their materials are made of non-biodegradable sources and repel mold
  • Fire resistance – Indeed, the best option to safeguard your property. It can take almost three hours for the fire to penetrate through them. However, it depends on the block size
  • Cost-effectiveness – AAC block price are not outrageous like other types of blocks; importantly, you don’t have to use much concrete and steel when using AAC blocks
  • Energy efficiency – Aerated blocks are good insulators and help to provide better temperatures in a building.

Conclusion

Thinking of using aerated blocks for your next building project, MGN Builders Merchants has a wide range of aerated blocks at the most competitive prices. These blocks are used in many building constructions, including residential, commercial, industrial, hotels, and hospitals. AAC blocks’ lightweight material provides the best thermal and sound insulation you need for your home today.

New report reveals the liquidation rate of businesses around the UK from the past year

  • New report reveals there have been over 8,000 company insolvencies since March 2020
  • Construction industry hit with the most company insolvencies since March 2020
  • Report reveals the liquidation rate of businesses around the UK
  • Businesses in Yorkshire most likely to undergo an insolvency event

Business Rescue Expert has analysed data from the past 12 months to reveal the Year of Lockdown report, which reveals the state of businesses, the liquidation rate and the sectors and regions most likely to undergo an insolvency event.

Since the beginning of the first lockdown, 11.2 million workers have been furloughed in the last 12 months which equates to 1 in 3 of the UK’s workforce.

There have been 8,205 company insolvencies from March 2020 to January 2021. Broken down by sector they were:


Sector
Number of insolvencies*
Construction1,634
Hospitality1,378
Retail1,355
Administrative & Support1,200
Manufacturing930
All others1,708

* (March 2020 – January 2021)

The construction industry has been hit the hardest, the halting of various building projects, both large and small scale, badly damaged the construction industry resulting in 1,634 construction company insolvencies.

There were £453.4 million in redundancy pay and other support benefits paid out in 2020, which is the highest amount in ten years and an increase of 31% from 2019.

The report also reveals that Yorkshire and Humber businesses were most likely to become insolvent in 2020.

Additionally, businesses in the North East, North West and West Midlands of England along with London were at greater risk compared to the national average (1 in 207) while Scotland, Wales and every other English region was less likely than the average.

The total number of corporate insolvencies actually fell in 2020, to their lowest recorded levels since 2007. The main reasons are the Government-backed Covid-19 support measures, such as CJRS, BBL and SEISS, the reduced HMRC enforcement activity, the temporary suspension of creditor recovery methods, moratoriums and other insolvency tools launching and the advice from financial service regulators that businesses in financial difficulty should be treated with “forbearance and due consideration”.

Chris Horner, Insolvency Director with Business Rescue Expert said: “Ominously, even with restrictions being lifted and economic activity rising, 2021 will be a worse year for insolvencies in several industries than the year of lockdowns was. Government support in the form of backed loans, furloughs and the temporary ban on winding-up petitions and other creditors actions are all expected to end sometime in 2021.

“Bounce Back Loan repayments and others will begin to come due, businesses will have to decide if they can re employ or redeploy their furloughed workers and creditors that have been under severe financial pressure themselves will finally have the ability to look for repayments that might be critical to their own survival.”
