Abstract
Foam concrete is one of the most widely used human-made cellular material, but its use as structural element is mainly limited by its low compressive strength. Nanomaterials has attracted much attentions as one of the most efficient reinforcing materials to cement matrix in recent years. However, there are only limited researches about the reinforcing effect of nanomaterials in foam concrete. In this research, a two-dimensional nanosheet, sulfonated graphene oxide (SGO), has been used system as a multifunctional nano-additives to improve the mechanical performance of foam concrete. The results suggest at only a small dosage of SGO (0.1 wt%), the compressive strength of foam concrete was significantly increased about 200% around a dry density of 400 kg/m3. In addition, the results also suggested the SGO is acted as a surfactant and able to improve the stability of the foam concrete at low dosage.
