Introduction The development and utilization of composite materials is increased.
This is indicated by using of composite materials in various application.
Because of the mechanical and physical properties, water hyacinth can also be used as a base material for composite materials [3].
The fracture part of materials were observed by SEM and to know the bonding between the water hyacinth and epoxy resin.

Influences of Admixtures on Properties of Foam Concrete with Iron Tailings XIAO Liguang1, a, LIU Chang1, b, ZHANG Shiting1, c and WANG Wenbin2, d 1School of Materials Science and Engineering, Jilin Jianzhu University, Changchun,130118,China 2Property Company of Changchun Real (group)Co.
Further, the foam concrete containing iron tailings was prepared by processing above raw materials including mixing, stirring, pouring, curing et al.
When all raw materials were dissolved and the mixture was heated to a certain temperature, crylic acid, SMAS and initiator solution were dropwise added into reactor respectively by constant flow pumps.
