摘要: The pore structure of foamed concrete is a significant characteristic since it affects properties such as strength and durability. To investigate these properties, the determination total air voids content not sufficient shape, size distribution may also be influential. understand formation after hardening, an investigation bubble foam (before adding to mixture) mixes (after hardening) discussed in this paper. These distributions have been quantified by examining selected parameters make comparison between them. In addition, void circularity factors determined examine phenomenon merging. order before mix, was found that treating with bitumen emulsion, clear image its can captured using optical microscope. Using technique, difference bubbles those pores within mixes. From factor results, there evidence for increased merging added volume (decreased density).
