A Study of the Mechanical Behavior of Concrete Using Additive and Waste Tires Rubber through a Diametral Compression Test Using Digital Image Correlation
Concrete is very resistant to compression, although its tensile strength is limited and it is regarded as a brittle material. One way to overcome this problem is through the use of plasticizing additives, as well as the introduction of fibers in the cement matrix. The aim of this study is to determine changes in the mechanical tensile strength of concrete when substitutes are found for sand in the form of waste tire rubber, with the introduction of plasticizer additive properties. The analysis was conducted by carrying out a diametral compression test combined with digital image correlation to measure the displacement and strain fields obtained with the applied loads. It was observed from the stress and strain values obtained in these tests that there is a reduction in tensile strength. This is accompanied by an increase in composite deformability and a rise in the percentage of waste.
