Foaming agent Cellular Lightweight Concrete


Preformed foam from the synthetic foaming agent was added into the geopolymer paste in various ratios of geopolymer paste to the foaming agent volume of 1:0.50, 1:0.67, 1:0.75, 1:1.00, 1:1.33, 1:1.50, and 1:2.00. Formerly, the foaming agent was performed by mixing the synthetic foam and water by using foam generators. The foam was then added and mixed for 5 minutes. Subsequently, the mixing rotation speed was lowered to avoid the formation of defects. The lightweight foaming geopolymer was poured into cubical molds and cured at an ambient temperature for 28 days. The dry density measurement for both the lightweight geopolymer types was performed on the cured specimens according to ASTM C138. The density of all samples was determined by dividing the mass of the dry lightweight geopolymer by its volume. The compressive strength of the lightweight geopolymer was measured at 7, 21, and 28 days using the compressive strength machine test instrument at the Physical Laboratory of PT Semen Indonesia (Persero), Tbk. The evaluation of the mechanical strength was performed according to ASTM C109. Compares the lightweight geopolymers produced from the synthetic foaming agent with that of aluminum powder. The polymerization was initiated with the dissolution of the aluminosilicate source into an alkaline activator solution, resulting in a dissolved alumina-silica species, followed by the initial polymerization, aided by the alkaline media to produce oligomers. This process was continued to a supersaturated condition. Afterward, the gel production transforms the structure into an amorphous, solid-bound structure. Diffractograms belong to the lightweight geopolymers synthesized using the foaming agent lightweight geopolymer and aluminum powder, respectively.
