Aerated Concrete Produced Using Locally Available Raw Materials
Abstract: Aerated concrete
materials were developed with abundant natural materials. Aerated concrete can
provide insulating qualities complemented with secondary structural attributes
when used as core in sandwich composites for building construction. A hybrid
binder that comprised lime and gypsum was used. Different foaming agents were considered
for production of aerated concrete, including saponin that is found abundantly
in different plants. Different formulations were considered, and the stability
of the foam structure as well as the density and early-age compressive strength
of the resulting aerated concrete were evaluated. One formulation comprising
lime-gypsum binder with saponin foaming agent, with a density of 0.53 g/cm3,
was further characterized through performance of thermal conductivity, split
tension, flexure, elastic and shear modulus and sorptivity tests. The results
pointed at the satisfactory balance of qualities provided by the aerated
concrete when compared with alternative aerated concrete materials.
