Possibilities to use textile cord waste from used tires for concrete

Abstract

The goal of the study was to determine the effect of waste tire cord yearn with attached rubber particles on the properties of concrete made of different types of cement (Portland cement without additives – CEM I, Portland cement with limestone additive – CEM II). The filament waste (added at 0 %, 2 %, 4 %, 6 %, 8 %, 10 % of the amount of fine aggregate) is water absorbing textile fibre additive with rubber particles, therefore a bigger amount of water is required to prepare the concrete mixture. The density and compressive strength of concrete reduces but water absorption increases with waste additive. The forecasted freeze-thaw resistance of concrete with recycled tire cord increases exponentially, slightly reduces when cement of type CEM II is used, however retains similar resistance in 1000 freeze-thaw cycles. The coefficient of thermal conductivity decreases approx. 35 %, when 10 % of recycled tire textile cord is added to concrete mixture.
