You might have heard of concrete before, but have you ever heard about lightweight concrete? What does it really mean? Does it mean that it is lighter than the normal concrete? This is our topic for today and will be discussed further in this post. So, don’t go anywhere and continue reading until the end. If you are wondering where to get lightweight concrete Selangor, 3D Resources is always the best option for you. Let’s dive into this post to know more about our topic for today.
Lightweight Concrete? What’s That?
Since you are here, you should know what lightweight concrete really means and how do they look like. Technically, lightweight concrete mixture is made with lightweight coarse aggregate. Lightweight coarse aggregate? What even is that? They usually consist of slate, shale and clay and these are the ones that give the low-density characteristic. The in-place density is usually from 1440 to 1840 kg/m³. Lightweight concrete is highly suitable for building modern structures. Modern structures nowadays would not require many cross-sections in the foundation. Hence why lightweight concrete is perfect for many modern buildings.
What are the Differences Between Lightweight Concrete and Normal Concrete?
This is probably the main question that might linger on your mind. When you heard the term lightweight concrete, you probably have the gist that it is lighter than normal concrete. Technically, lightweight concrete contains higher water content than normal concrete, This is only one of the subtle differences between these two types of concretes. As mentioned previously, the weight and the ability to be used for modern buildings are also different. Apart from that, lightweight concrete too is known to be cost-effective.
Three Types of Lightweight Concrete
There are a few types of lightweight concrete that you will get to know today, These are among the available types of it:
- Lightweight Aggregate Concrete
You probably have seen this term before. As you have read previously, this type of lightweight concrete consists of lightweight aggregates such as perlite, clay, slate, Volcanic Pumice and shale. The impact of its thermal conductivity may be affected by the presence of weaker aggregates in the mixture which would cause the strength to reduce.
- Aerated or Foamed Concrete
Also known as gas concrete, large voids are introduced into the concrete or mortar moss which explains the name. Normally, voids are inserted using an air-entraining agent, through a chemical reaction. This type of concrete does not need flattening and it is self-compacting. This is very convenient for those who need to utilise it often.
- No Fines Concrete
This type of concrete is formed when fine aggregates are secluded from the mixture. This results in concrete that only comprises coarse aggregates and large voids. No fines concrete is best used for load-bearing walls. It can also be utilised for indoor and outdoor constructions. Due to the content of cement and its lower density, it is not suitable to be used with reinforced concrete.
Both lightweight concrete and normal concrete are frequently used and aren’t really new in the industry. It all depends on what you are going to use it for and its capability to suit the building or structure.
