Lightweight concrete is a material that is used for the construction industry. Lightweight concrete is a material that is mixed with other combined lightweight bristles such as slate, shale, or clay that gives it a block of concrete with a low density. The structure of this concrete has a density that is up to 90 to 115 lb/ft³ which is about 1440 to 1840 kg/m³. A normal weight concrete usually has a density of about 140 to 150 lb/ft³ which is around 2240 to 2400 kg/m³.
What does lightweight concrete is used for?
Lightweight concrete is usually used for a modern building structure that is using the minimum amount of cross-section. It also used to make a smooth base for the building and has been an alternative material for normal-weight concrete. The examples of buildings that are using lightweight concrete in it are house, modern buildings, stadium, bridges, and many more. The reason why many building nowadays is using lightweight concrete is that lightweight concrete has good thermal properties which the concrete is a good heat conductor. It also has good strength and durability that can make the building become sturdy and safe to use.
Types of lightweight concrete
There are many different types of lightweight concrete that have been used in the construction industry for many years. The first example is the aerated concrete. Aerated concrete a lightweight concrete that has the lowest density as well as strength and thermal properties. This concrete can be nailed, cut, and screwed but it can never be combusted. Aerated concrete is concrete that contains lime, sand, cement, and other material that contains silica.
The next example is lightweight aggregate concrete. Lightweight aggregate concrete is commonly used to build a load-bearing in the cavity wall. This concrete is used for that purpose back in the early 1950. But now, lightweight aggregate concrete has been developed into a new type of lightweight aggregate that is much more strong and also suitable to use for the building structure. The lightweight aggregate concrete has been developed into several types such as foamed slag, pumice, expanded clays and shales, and sintered pulverized.
The advantages of using lightweight concrete
Lightweight concrete has brought many advantages to the construction industry. The advantages that lightweight concrete has been it can make the construction process of the building become much faster. Other than that, it also can decrease the cost to buy the materials for the building and it was easy to get. Next is lightweight concrete has high durability that it can withstand any impact or effects of its surroundings such as natural disaster, physical impact, or even chemical attack. Also, it has a low thermal conductivity that can withstand heat or fire. This may help to slow down the fire from spreading if there is any fire disaster happening in the building.
In conclusion, lightweight concrete is one of the most common materials that is being used in construction work. It has many advantages that bring benefits to the industry. Many buildings nowadays have been using lightweight concrete because of its characteristics and properties that can ensure the building lifespan and safety when using it.
