Cur-ris concrait aotrom | Luchd-ionaid foam àrd-choileanadh airson concrait cealla
Aig àm togail thogalaichean, Bithear a’ cleachdadh cruadhtan foam mar àite airson cruinneachadh grinn. Tha seo air a dhèanamh le bhith a 'measgachadh sioda stèidhichte air saimeant, anns a bheil uisge agus stabilizer. The mixture can be pumped into molds or poured into structural elements.
This type of concrete is stress-free to construct. Ge-tà, it is recommended to wear appropriate protective eyewear while handling it. Cuideachd, it is important to mix the dry ingredients thoroughly. It is best to use long-sleeved shirts to prevent the mortar from sticking.
A foaming agent for concrete is composed of a number of surfactants, preservative agents, uisge, agus fuasglaidhean. It is used in building foundations and pavements. It is also considered to be a cheaper alternative to conventional cement.
The compressive strength of the foaming agent was measured. It was found that the compressive strength of the mixture was higher than the literature value for the same density.
The flexural strength was also measured. It was found that the flexural strength of the mixture was lower than the sample with the same density. It was also observed that the density of the foamed concrete increased as the pore size was decreased. It was also observed that the air-voids were uniformly distributed in the foamed samples.
The density of the hardened foamed concrete was measured using 150 mm x 150 mm x 150 mm standard cubes. It was found that the density of the samples with the density of 550 kg/m3 and 800 kg/m3 were slightly higher than the density of the samples with the density of 500 kg/m3 and 1000 kg/m3. It was also observed that the air-voids in the specimens with the density of 720 kg/m3 and 700 kg/m3 were lower than the specimens with the density of 500 kg/m3. It was also observed that some of the specimens with the density of 800 kg/m3 had larger pores.
