Advantages, Disadvantages and Uses of Lightweight Concrete

What is Lightweight Concrete

Lightweight concrete is a mixture of fine coarse aggregates such as clay, slate, shale for giving low density. The weight of this structural lightweight concrete ranges from 1440 to 1840 kg/m3.

Whereas, Normal weight of concrete ranges between 2240 to 2400 kg/m3

Rule of Lightweight Concrete 1. The main reason behind constructing this type of concrete is the introduction of air into the concrete.

2. Concrete can be filled up with gas bubbles or air.

3. During concrete preparation, sand should be omitted.

Characteristics of Lightweight Concrete 1. Reduce Density The light type of concrete is used for filling and the heavier one is for structural reasons. The density ranges varies between 3001200kg/m3.

2. High Strength As compared to its density, the lightweight concrete has high binding strength. As the density increase, the strength of the concrete also rises.

3. Longevity Aerated concrete is alkaline based due to its sponginess and low alkalinity. Hence, it is not a good content for steel reinforcement.

Therefore, the reinforcement which will be used want special treatment to stop corrosion. Try to select top and professional reinforcement bar manufacturer for corrosion free construction building.

4. Thermal Insulation The insulating power of lightweight concrete is about three to four times that of bricks and approximately ten times of concrete. A 20 cm thick aerated concrete has equal degree of insulation compared with a 40 cm brick.

5. Fire Resistance Lightweight concrete has high quality of resisting fire. It is essential for securing other structures from the effect of fire and due to its low thermal conductivity power it is possible.

6. Soundproofing This type of concrete doesn’t have the kind of sound isolation that dense concrete has.
