Li-additives tsa konkreite tse bobebe li ka sebelisoa ho nkela likarolo tse teteaneng tsa tlhaho ka konkreite ea meralo. Li-additives tsena li ka fokotsa litšenyehelo tsa thepa le ho sebetsana. They can also increase the thermal insulation of the concrete and improve its fire resistance.

Foamed concrete is one of the most commonly used lightweight concretes. It is produced through a pre-forming process. The foaming agent introduces randomly distributed air bubbles into the mixture. This results in lower density.

The main components of a foamed concrete are the foaming agent and stabilizer. The stabilizing agent is usually added in the slurry of the foamed concrete batch.

Aside from reducing the cost of the material, these additives can improve the structure and the performance of the lightweight concrete. Using these additives can help in reducing the steel requirements for the project.

Several studies have been conducted to investigate the compressive strength of various types of lightweight concrete. It has been observed that the densities of concrete in the range of 350 ho 50 kg/m3 are acceptable.

Leha ho le joalo, the densities were slightly lower than those in the case of normal weight concrete. Some of the studies investigated the influence of nanosilica on the densities of foamed concrete.

Another study investigated the influence of supplementary cementitious materials on the performance of ultra-lightweight foamed concrete. The authors found that the inclusion of these ingredients reduced the shrinkage rate of the concrete.

Ho feta moo, the use of nanosilica improved the strength of the concrete by refining the pore structure. Holim'a moo, the density of the concrete increased with the incorporation of nanosilica.
