EXPERIMENTAL STUDY ON FOAM CONCRETE - TJPRC

2016-6-10  Foamed concrete is not a particularly new material, its first patent and recorded use dates back to the early 1920s. According to Sach and Seifert (1999), limited scale production began in 1923 and, according to Arasteh (1988), in 1924 Linde described its production, properties and applications. The application of foamed concrete for construction works was not recognized until the late 1970s, when it began to be used in the Netherlands for filling voids and for ground engineering applications. Significant improvements in production methods and the quality of foaming agents over the last 15 years have lead to increased production and broadening of the range of applications. An extensive research program carried out in Holland helped promote foamed concrete

Palm-based polyurethane (PU) particles were used as lightweight aggregates in creating concrete systems. Concrete systems contain palm kernel oil-based polyol (PKO-p) reacted with 2,4-methylene diphenyl diisocyanate (MDI). In this study, polymer concrete was improved to achieve the optimum level of PU with the lowest possible density.

2021-6-1  In this study, the decrease in strength was found to be 55, 48, 11 percent, and 48, 44, 10 percent respectively for protein and synthetic foamed concrete. This is due to the heavy use of foam to reach the target density of foamed concrete, air bubbles in enormous numbers in the mixture which causes a reduction in the binder material volume hence depleting the compressive strength . However, there is a substantial increase in the strength of protein-based foamed concrete
