“…Regardless of their significant advantages in comparison with conventional construction materials, the mechanical properties of polymer composites are highly susceptible to the type of resin and reinforcement (or aggregate) employed, as well as to the quantity of both components [3][4][5][6] . However, the main problem with polymeric materials arises from the viscoelastic properties of the polymer, which result in creep and a high sensitivity to temperature [7][8][9][10] . The effects of temperature on the mechanical properties of polymers change considerably, especially within the heat distortion temperature range.…”

This paper presents the results of an experimental program to investigate the effect of temperature on the performance of epoxy and unsaturated polyester polymer mortars (PM). PM is a composite material in which polymeric materials are used to bond the aggregates in a fashion similar to that used in the preparation of Portland cement concrete. For this purpose, prismatic and cylindrical specimens were prepared for flexural and compressive tests, respectively, at different temperatures. Measurements of the temperature-dependent elastic modulus and the compressive and flexural strength were conducted using a thermostatic chamber attached to a universal test machine for a range of temperatures varying from room temperature to 90 °C. The flexural and compressive strength decreases as temperature increases, especially after matrix HDT. Epoxy polymer mortars are more sensitive to temperature variation than unsaturated polyester ones.

“…PC is generally used in precast applications, including manholes, pipes, and chemical-resistance vessels, due to its favorable material properties, such as high mechanical strength, strong chemical resistance, as well as its short time to obtain satisfactory serviceability [1][2][3]. In addition, PC is widely accepted for rapid repair of pavement and bridge decks, as well as in corrosion protections of a variety of in-service infrastructures exposed to aggressive environments, in order to extend their lifespans due to its excellent durability, strong adhesiveness, and rapid hardening characteristics [1,4]. As binders for PC, epoxy resin, unsaturated polyester (UP) resin, polymethyl methacrylate (PMMA) resin, vinylester resin, and furan resin are popularly used [2,5].…”

Ensuring an appropriate casting time window is of great importance for achieving desired quality and performance of aging materials. In this paper, the effects of promoter and cross-linking agent on the working life-the period a mixture stays in a workable condition-of low-temperature-cured acrylic polymer concrete (PC) are investigated in order to develop mixture proportions that can be effectively applied in cold weather conditions. The experimental variables included in this study are: (1) curing temperatures (´20,´10 and 0˝C); (2) N,N-dimethyl-p-toluidine (DMT) contents (0.5, 1.0, 1.5 and 2.0 phr (parts per hundred parts of resin)); and (3) trimethylolpropane trimethacrylate (TMPTMA) contents (0, 2.5 and 5 phr). Results indicated a strong relevance between binder's setting time and PC's working life. Additionally, it was observed that the working life of acrylic PC was substantially shortened as the curing temperature and contents of DMT and TMPTMA increased. Results of a two-way analysis of variance (ANOVA) revealed that TMPTMA had a greater impact on the working life than DMT. Finally, this study developed an equation that can be used to estimate PC working life, based on the binder's setting time. The findings of this study will be used as valuable information for cold weather applications of acrylic PC.

“…Shokrieh (2011) observed that the compressive strength of the optimally designed PC is not affected by heating and cooling cycles. Wang and Wong (2007) found that the elastic modulus remained almost unchanged until 300-400 8C.…”

Polymer concrete composites have been accepted by various manufacturers and widely used as a structural material for machine tools due to their tremendous properties such as compressive stress, flexural strength and damping capacity. In the current scenario, it has been found that many industrial waste materials can be used as aggregates/fillers for polymer concrete (PC) composites. Also by adopting suitable recycling methods, polyester polymer can be obtained from industrial waste and can be suitably used as a binder for the fabrication of the composites.
