Methods and assesment of heavy metals leaching from construction materials
Języki publikacji
Abstrakty
The civil engineering structures and elements, wherein concrete makes the principal component, have been in common use and can be found all around us. Since numerous waste materials and industrial by-products have been used in the production of cement and concrete, attention should be paid to the environmental impacts of contemporary construction materials. Within that area, it is especially important to evaluate the release of heavy metals to the aquatic environment and/or to the soil. The paper presents the testmethods which are applicable in the assessment of the leaching level of heavy metals from the construction materials.
