Synergistic effect of animal oil or butter and hydrogen peroxide on physical and mechanical properties of porous alumino-siliceous materials

Abstract

Porous alumino-siliceous (PAS) materials are attractive for use in a wide variety of construction and adsorption materials. In the present study, the porous alumino-siliceous materials were synthesized by a geopolymerization method in a reaction from ceramic waste, metakaolin, and an alkaline solution, H 2 O 2 (as a foaming agent) and either pork lard or butter (surfactants). Different amounts of the surfactants (2.5-15 wt%) were added to the samples. The pore shape in the PAS materials was affected by the type of surfactant used. PAS materials with small open pores and high porosity were successfully fabricated with butter as a surfactant. The compressive strength value trend was related to total porosity. The relationship between compressive strength and porosity was found to be consistent with a model proposed by Ryshkewitch. The results suggest that this material can be used as a foam material.

Geopolymer Foams—Will They Ever Become a Viable Alternative to Popular Insulation Materials?—A Critical Opinion

“…Fresh geopolymer foams have been stabilized by adding nonionic surfactants such as Tween 80-a polyoxyethylene 20 sorbitan monooleate (C 64 H 124 O 26 ; VWR BDH Prolabo) and Triton X-100-a polyethylene glycol tertoctylphenyl ether (C 14 H 22O , (C 2 H 4 O)n, n = 9-10; Sigma-Aldrich, Poznań, Poland) [36]. Pork lard or butter, for example, was used as a surfactant [44]. Olive oil has also been considered, as well as agents, such as Sika Lightcrete 02 (containing, e.g., 40 wt% solution of fatty acid), amide, and sodium salt of C 14 -C 16 sulfonic acid in water [36].…”

Determination of the Influence of Hydraulic Additives on the Foaming Process and Stability of the Produced Geopolymer Foams

“…Chemicals are also added to reduce the viscosity, e.g., polyacrylic acid (Dolapix CE-64) [ 25 ]. Good results are also obtained with calcium stearate [ 26 ].…”
