It was also reported that glass powder can be used as
a replacement for cement up to 10% to increase the compressive
strength of concrete [26]. The presence of polymer particles in the
dispersion is restricted to the capillary force at the interface of the
aggregate and the bulk polymer-cement phase and the polymer
products included in these hydration products do not contribute to
strength development [23]. This has been further supported with
the results of earlier researchers that no influence of polymer
modification on the strength was noticed in standard cured and
water cured specimens as long as they are not dry cured [1,5]. This
suggests that the polymeric powder in the GRP waste might have
degraded from its virgin resin characteristics and hence, the presence
of the polymeric compound in GRP waste powder might have
not contributed to enhance the compressive strength.
