DEVELOPMENT OF NATURAL BASED FOAMING AGENT FOR THE POTENTIAL USE IN FOAM CONCRETE

摘要

The feasibility of the use of locally available sesame seeds (SS) as an alternate to synthetic foaming agents for foamed concrete production has been assessed in this study. The use of such eco-friendly and abundantly available material as foaming agent can facilitate wider use of foamed concrete. The various parameters involved in the extraction of surfactant from SS, such as SS concentration, duration of heating, heating temperature, sodium hydroxide concentration (alkali for hydrolysis), ammonium chloride concentration (for neutralization) and sodium fluoride concentration (antiseptic) are considered in the present study. Also, the foam generated at the chosen surfactant production parameters is observed to result in foam concrete with acceptable properties as per ASTM standards.
