Abstract:
The influence of a silane coupling agent on the mechanical properties of polyester polymer concrete with and without glass fiber reinforcement has been investigated. The silane was incorporated into the polymer concrete systems either by pretreating the aggregates and fibers or by directly adding it into the resin (integral addition method). The flexural properties of polyester polymer and polymer concrete were studied in four-point bending (third point loading) at room temperature. The results indicate that the silane treated aggregate systems increase in flexural strength by more than 50 percent when compared to the untreated systems. The increase in strength is also dependent on the amount of polymer in the polymer concrete. At equivalent loading levels of silane, superior flexural properties were obtained with the pretreatment method than with the integral addition method. The improvement in strength due to the silane coupling agent is explained in terms of chemical interaction between the polymeric matrix and filler. Addition of glass fibers enhances the strength, stiffness and toughness of polyester polymer concrete, and silane treatment of glass fibers helps to further enhance these properties. Behavior models are proposed to predict the enhanced flexural strength of polyester polymer concrete due to pretreatment, integral addition and fiber reinforcement.

The use of silica fume in concrete has attracted a great deal of interest in the past several years. For those individuals not directly involved with silica fume, it may appear that the interest has all been from a research point of view. This is not corr

If concrete is to be permitted to demonstrate that the materials and proportions selected for its production were appropriate for its intended service, the construction practices used in making, placing, consolidating, and curing it must also be appropria

During the past 50 years, there have been significant changes in the composition of general-purpose concrete. Along with changes in the performance of portland cement, changes have come about due to the inclusion of chemical and mineral admixtures,
