“…The current most commonly used foaming agents are mainly synthetic-based (SF), animal/plant-protein-based (AF and PF, respectively), and rosin-based (RF). The foaming multiples and foam stability of PF and RF are usually poor [24]. In this study, therefore, SF and AF were selected as foaming agents.…”

In order to explore the effect of the foaming agent type on the properties of foamed mixture lightweight soil mixed with bauxite tailings (FMLSB), low-density (437.5 kg/m3 and 670 kg/m3) and high-density (902.5 kg/m3 and 1170 kg/m3) FMLSB were prepared using protein-based and synthetic-based foaming agents (AF and SF, respectively). The foam stability, micro characteristics, compressive strength, fluidity, and volume of water absorption of the FMLSB were investigated. The results showed that the foam made from AF had better strength and stability compared to SF. The internal pore sizes of both AF- and SF-FMLSB at low density were large, but at high density the internal pore sizes and area porosity of AF-FMLSB were smaller than those of SF-FMLSB. In terms of compressive strength, the compressive strength of AF-FMLSB was improved by 17.5% to 43.2% compared to SF-FMLSB. At low density, the fluidity of AF- and SF-FMLSB is similar, while at high density the fluidity of AF-FMLSB is much higher than that of SF-FMLSB. In addition, the stable volume of water absorption of SF-FMLSB is smaller than that of AF-FMLSB at low density, and the corresponding water resistance is better, but the situation is reversed at high density.

“…However, an important role in the performance of foamed concrete is played by the foaming agent, which is used to make foam and then form enclosed pores [62]. Foaming agents can be classified into two groups, synthetic-and natural-based foaming agents [63], or five categories: rosin, synthetic, protein, composite and the latest type [64][65][66]. Some foaming agents are polymer admixtures [22,67].…”

The components of foamed concrete have a significant effect on its properties. Protein-based foamed concrete is used much more often. This study aims to assess the properties of foamed concrete with a density of around 500, 700, 800 and 1000 kg/m3 formed by using a synthetic polymer-based foaming agent. The distribution of pores, wet and dry density and compressive strengths were evaluated. In addition, the creep deformations of foamed concrete with different densities were measured. The difference in density of up to 170 kg/m3 for the highest densities was obtained. Foamed concrete with higher densities (700 and 800 kg/m3) showed similar characteristics of pores, which were different from those of samples with a density of 500 kg/m3. Compressive strength equal to 5.9 ± 0.2, 5.1 ± 0.2, 3.8 ± 0.3 and 1.4 ± 0.2 MPa was obtained for foamed concrete with a density of 500, 700, 800 and 1000 kg/m3, respectively. The obtained compressive strengths were higher than those found in the literature for the foamed concrete with the same densities. With increasing density, smaller creep deformations were obtained. Creep deformations were 509, 495 and 455 με for samples with densities of around 500, 700 and 1000 kg/m3 respectively. Deformation under long-term loading took place up to 90 days, regardless of the density of the foamed concrete.

“…Commonly, lightweight foam consists of cement, water and foam agent in mortar phase [2]. The lightweight foam concrete have well resistant to the heat and act as insulation for building materials [3,4,5,6]. FUSCOF act as admixture to the mortar and previous researchers revealed that admixture added will influence on the for lightweight foam concrete strength.…”

This paper presents the potential of utilizing used cooking oil as a foaming agent in the production of lightweight concrete. This morphology study is to observe the development of Fuscof as foam agent in lightweight greencrete after ambient curing process. Foam formulated was produced derived by utilization the waste of used cooking oil. The mortar phase of FUSCOF lightweight greencrete was formed. Then, the material morphology of the lightweight greencrete was analysis by using FESEM. The morphology of FUSCOF greecrete was then compared with a lightweight foam produced from commercial synthetic foam agent. The water cement ration has been determined for this mix design is 0.6. The density of FUSCOF lightweight greencrete was 1200. The age of the ambient curing process was varied between ±30-day and ±60-day. The maturation of the mortar was observed. As a result, the major element was Calcium, Ca has been detected by EDAX.
