| Abstract |
The aim of the study is to analyze physical and mechanical properties of cement composite specimens by way of adding varying contents of a selected range of Polyacrylamides(PAMs) as interfacial coupling agent for organic fibers. In line with the aim of the study, mode of failure has also been carefully examined. Based on the experiment, the study attempts to suggest a correlation between interfacial matrix and physical properties of organic fiber-reinforced cement composite. In the experiment, N-PAM(Nonion), C-PAM(Cation) and A-PAM(Anion) were used as interfacial coupling agent for organic fibers such as PVA and acrylics. The experiment has demonstrated A-PAM for PVA fibers and C-PAM for acrylic fibers to be an optimum interfacial coupling agent for the respective organic fibers in terms of both interfacial adhesion and physical properties. When an inappropriate interfacial treatment agent was used, a number of organic fibers were found to have been pulled out and the matrices were found to be loose. It is evident from the experiment that there is an optimal PAM as interface treatment agent for respective organic fibers, producing high degree of compactness of the matrix as well as excellent physical properties including interfacial adhesion. The experiment has demonstrated that when PVA fibers are treated with A-PAM and acrylic fibers with C-PAM, PVA fibers proved to be superior to acrylic fibers in terms of adhesion to cement matrix as well as in terms of physical and mechanical properties. |
