Strength Development Characteristics and Economic Efficiency of Low Temperature Cured Acrylic Polymer Concrete: The Effect of Additive Type

초록

This paper presents the strength development characteristics and the economic efficiency of low temperature cured acrylic polymer concrete containing different types of additives. In this study, two separate cases were mainly investigated: (1) when only MAA (polar monomer) was used as an additive and (2) when silane (coupling agent) in combination with TMPTMA (cross-linking agent) was used as an additive. The experimental results showed that compressive strength of over 80 MPa could be obtained in both cases even in low curing temperatures (i.e., 0 and -20 degrees C). Also, the result of economic efficiency analysis showed that the use of MAA yielded a 10% less material cost than the use of TMPTMA and silane. This finding indicates that the use of MAA can be more beneficial from an economic perspective.
