Influence of addition of shredded rubber waste on deformability of binder-bound anthropogenic material mixtures

[摘要] Construction is one of the industrial sectors responsible for the use of large quantities of natural raw materials. This fact makes it necessary to look for new technologies of producing construction materials based as much as possible on waste materials. Such a solution could have positive effects on the environment and reduce construction costs. This paper presents the results of a study on the deformability of a mix made from anthropogenic waste combined with a hydraulic binder. The presented mixes consist of unburnt coal mining slates (mine waste), shredded rubber waste, silica fly ash and CEM I 42.5 R cement. Samples with two different contents of shredded rubber waste 0% and 10% were made from the mixtures and subjected to destructive compressive strength testing. The strength testwas combined with sample deformation measurement performed with the Aramis 3D Video Correlation System. The results presented show the effect of the shredded rubber waste content on the deformability of the sample.
