Resumen
The purpose of this paper is to report on an experimental study that explores the effect of using recycled rubber in concrete. in this research 5 types of mixture were made, one with a conventional aggregates and the other by replacing 10%, 30%, 50% and 70% of sand by rubber crushed, were carried out for each percentage 16 samples to be subjected to compression tests in ages of 7, 14, 28 and 56 days in order to compare their behaviour with the compressive strength of an ordinary concrete, also with a variable load permeameter was evaluated the permeability of each sample to have a reference value for the purpose of determining how much water is filtered through its structure. the main results show that the compressive strength is reduced due to use rubber and its compressive strength decreases even more if the samples contain more rubber crushed. with regard to the permeability, all samples are considered to have a high permeability and this value is proportional to the amount of rubber in the sample, so that, the samples with the highest percentage of rubber allow faster water seepage. finally with the results, it can be concluded that this type of concrete using rubber can be used in elements which do not require large applications of compressive strength as sidewalks, in addition, it could be possible to take advantage of the filtration capacity of water in this concrete to be used as alternative drainage in those elements.
