Abstract
The effects of two silane coupling agents, γ-methacryloxy propyl trimethoxy silane and γ-amino propyl triethoxy silane, on the compressive strength of polyester resin concrete (PC) is studied by using two methods of application of the coupling agent, namely by (a) pre-treatment of the aggregates in an aqueous solution of the silane, (b) by adding the silane to the resin as an integral blend additive. The performance of the two methods, evaluated in terms of gain in the compressive strength, is compared. Method (b), which is preferable due to its convenience, showed comparable performance to method (a) only at the optimum level of loading of the coupling agent. Changes in X-ray diffraction of “PC with coupling agent” prepared by method (b) were similar to those in silane-treated sand particles, which support the migration theory of the coupling agent reported in the literature. Grain size analysis of silane-treated sand showed evidence of better aggregation in the presence of one coupling agent as compared to the other.
