The influence of elevated temperatures on thermal properties of concrete with crumb rubber

Popis výsledku v původním jazyce

The paper deals with the application of crumb rubber made by re-processing of disposed automobile tires in production of concrete containing fine aggregate in the size up to 4 mm only. In concrete composition, nature silica sand was replaced by crumb rubber in the dosage of 10-30 % by mass. The water binder ratio of 0.5 was maintained similar for all studied concretes. For the examined materials, basic physical properties and in particular thermo-physical properties at elevated temperatures were investigated after 28 days of samples water curing. Obtained experimental results indicated that thermal conductivity as well volumetric heat capacity were strongly effected by temperature due to the release of aromatic oils and liquid additives coming from temperature loaded crumb rubber, porosity changes and water loss.
