Abstract
Bitlis rock is used as a construction material and comes from the lava emitted by volcanoes and their subsequent transformation into ignimbrites. This type of rocks has been characterized physically, chemically, toxicologically and radioactively using different procedures including determination of the coefficient of thermal conductivity, gamma spectrometry, ultrasonic speed test, ICP masses and metal extraction. The results indicate that Bitlis rocks have an ACI greater than 1, although their content of radon is lower than other rocks of volcanic origin. Leaching of metals from these rocks indicates that Pb and Cd can provide an infiltration level in the field higher than the level permitted by TCLP and they have undesired toxicological risks. The percentages of extraction of other metals also point to this infiltration problem. Despite this, the material offers good qualities for usage as a building material such as its thermal coefficients.
期刊介绍:
Materiales de Construcción is a quarterly, scientific Journal published in English, intended for researchers, plant technicians and other professionals engaged in the area of Construction, Materials Science and Technology. Scientific articles focus mainly on:
- Physics and chemistry of the formation of cement and other binders.
- Cement and concrete. Components (aggregate, admixtures, additions and similar). Behaviour and properties.
- Durability and corrosion of other construction materials.
- Restoration and conservation of the materials in heritage monuments.
- Weathering and the deterioration of construction materials.
- Use of industrial waste and by-products in construction.
- Manufacture and properties of other construction materials, such as: gypsum/plaster, lime%2
