Concrete production has high adverse effect on the quality of environment, and its sustainability is open question for material researchers and producers. In addressing the environmental concerns of concrete manufacturing and problems relating to the disposal of wastes and industrial by-product and also economic advantages, application of secondary raw materials in composition of concrete mix is of the particular importance both from the environmental and financial point of view. A substantial growth in the consum...

The handling and disposal of voluminous sludge produced from water treatment plants poses difficulty to environmental scientist and engineers. In fact, its environmental friendly management and disposal is challenging task and requires careful consideration. In this study, sewage sludge ashes were examined as potentially supplementary cementitious materials. The raw sewage sludge was provided by two different municipal waste water treatment plants, coming from Poland and Greece respectively. The calcination of pre...

The buildings energy performance is becoming increasingly important, because of environmental restrictions connected with CO2 emission and rising costs of fuel end energy. Respecting sustainability issues, design of buildings with improved thermal properties and optimum energy performance is preferred, whereas specific attention has to be paid not only to the design of building envelopes, but also to the thermal insulation of buildings subsoil. To obtain buildings with high thermal resistance and sufficient therma...
