Abstract
The goal of the study was to determine the effect of waste tire cord yarn 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%, and 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. With waste additive, the density and compressive strength of concrete reduces, but water absorption increases. The forecasted freeze-thaw resistance of concrete with cement type CEM I and recycled tire cord increases and slightly reduces when cement type CEM II is used, however retains similar resistance in about 1000 freeze-thaw cycles. The coefficient of thermal conductivity decreases approx. 35%, when 10% of recycled tire textile cord is added to concrete mixture.
Highlights
We found that water demand increased approximately 100% with the addition of 10% of waste tire cord yarn to the concrete (Table 4)
Higher density was observed in specimens with type cement without additives (CEM I) cement; this can be explained by higher density of the cement (Table 4)
The images show that the amount of fine closed pores increases with higher waste content in the mixture. These closed pores improve freeze-thaw characteristics of concrete but have a negative effect on the binding of the waste with hardened cement paste leading to lower compressive strength
