The difference between foam concrete and lightweight aggregate

2022-01-17 17:05:44  Blog

Foamed concrete and lightweight aggregate concrete are both lightweight concretes.

What is foam concrete?

Foamed concrete is to fully foam the foaming agent diluent by mechanical means through the foaming system of the special equipment for foamed concrete, and evenly mix the foam with the cement slurry, and then conduct in-situ construction through the pumping system of the special equipment for foamed concrete. A new type of lightweight thermal insulation material with a large number of closed pores formed by natural curing.

Foamed concrete is a member of the concrete family. In recent years, much attention has been paid to the research and development of foamed concrete at home and abroad, making it more and more widely used in the field of construction and transportation.

Ceramsite concrete 

What is Lightweight Aggregate Concrete?

Concrete prepared with light coarse aggregate, light sand (or ordinary sand), cement and water, whose dry apparent density is not greater than 1950 kg/m3, is called light aggregate concrete.

Lightweight aggregate concrete is divided into: ① Natural lightweight aggregate concrete. Such as pumice concrete, volcanic slag concrete and porous tuff concrete. ② Artificial lightweight aggregate concrete. Such as clay ceramsite concrete, shale ceramsite concrete, expanded perlite concrete and concrete made of organic lightweight aggregates. ③Industrial waste light aggregate concrete. Such as cinder concrete, fly ash ceramsite concrete and expanded slag bead concrete. 

In the current practical application, ceramsite concrete is the most used lightweight aggregate concrete.

We can basically believe that foam concrete is the first choice for building slopes. Its advantages are obvious, and the summary is as follows:

1. The convenience of construction is beneficial to the construction period

2. The light weight is conducive to reducing the load of the building, and it has obvious economic benefits.

3. Good compatibility with building structure and synchronous life

4. The compressive strength can meet the design requirements

5. Low engineering cost
