Silane and TMPTMA effect the compressive strength of acrylic polymer concrete

Thursday, 19 June 2014

A study by Korean researchers addresses the effects of additives on the compressive strength of low-temperature cured acrylic polymer concrete (PC).

They investigated three curing temperatures (0°C, -10°C, and -20°C) and five ages (6, 12, 24, 72, and 168h) with two different types of additives [trimethylolpropane trimethacrylate (TMPTMA) and silane].

Findings are effectively used in cold regions

As a result, the compressive strength tended to decrease as the curing temperature decreased. The compressive strengths at 24h were approximately 90% of those at 168h at both curing temperatures of 0°C and -20°C, indicating that the rate of early age strength development was quite high even at a very low curing temperature range. The results of two-way variance analysis revealed that silane had a greater impact on the compressive strength than TMPTMA. About 13-23% strength improvements with a 168h compressive strength of over 80MPa could be obtained at -20°C by adding silane. Furthermore, this study proposed optimum mixture proportions of acrylic PC that generate a working life of 50-70 minutes with a compressive strength of 80MPa at subzero temperatures. The findings are expected to be effectively used in field applications of acrylic PC, especially in the cold regions during winter season.

The study is published in: Journal of Applied Polymer Science.
