Abstract
The construction industry plays a pivotal role in the treatment and reuse of used tires, and the research on rubberized concrete holds immense potential. The present study employs micro- calcium carbonate (MCC) for the modification of the crumb rubber (CR) concrete substrate and its application in 3D concrete printing technology (3DCP). Firstly, the lightweight and thermal insulation properties of 3D printed rubber concrete are explored by testing the thermal conductivity and density of the mixtures materials. Then the performance enhancement mechanism of MCC on 3D printed rubber concrete is analyzed through mechanical property tests. Ultimately, the compatibility of the mixtures with the self-developed concrete 3D printer is verified by the fluidity test, buildability test and interlayer bond strength test and obtained the optimal ratio of MCC modified 3D printed rubber concrete. This study is helpful to increase the application of recyclable rubber materials in the construction industry and reduce the environmental pollution caused by rubber and provide a reference for the application of micron-material-modified rubber concrete in 3D construction printing.
