In order to further improve the comprehensive utilization rate of phosphogypsum, this article used a single factor experiment to study the effect of the dilution ratio of the composite foaming agent solution with a mass ratio of AOS, animal protein and K12 at 1: 1 : 1 on the porosity and pore structure of phosphogypsum-based foamed building gypsum. And the relationship between porosity and strength, thermal conductivity was studied. The research results show that when the apparent density is between 600 kg/m3 and 800 kg/m³, the thermal performance of phosphogypsum-based foamed building gypsum is better than that of the other four groups of foam insulation materials. When the apparent density is greater than 900 kg/ m³, the compressive strength is much higher than that of the other gypsum-based foam materials. The relationship between thermal conductivity and porosity is consistent with the Maxwell-Euchen1 model, while the relationship between compressive strength and porosity is more consistent with the Hasselmann equation. This study provides data support for the production of phosphogypsum-based foamed building gypsum. [ABSTRACT FROM AUTHOR] |
