Since the construction sector uses 50% of the Earth's raw materials and produces 50% of its waste, the development of more durable and sustainable building materials is crucial. Today, Construction and Demolition Waste (CDW) is mainly used in low level applications, namely as unbound material for foundations, e.g., in road construction. Mineral demolition waste can be recycled as crushed aggreg...

The increase in cost of carbonaceous materials, as well significant costs industrial waste, have prompted scientists to use alternative raw materials components the construction industry. This study investigated suitability waste products from coke industry modifying agents for polymer bitumen. by-product coking reaches a high level silicon and is called silicon-containing additive (SCA), compo...

The paper aims to study cellular concrete with a new approach of formulation without an autoclave, the use aluminum waste and incorporation mineral additions into sand evaluate its physical mechanical properties. In this experimental study, two types are prepared, based on crushed dune 15% slag 10% pozzolana, as replacement. An program was performed determine compressive strength at 28 days, de...

Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is abundant in some parts of Europe and Turkey as well as Western United States is sepiolite. A laboratory study was undertaken to investigate the feasibility of sepiolite as a liner ...

This paper aims at providing a preliminary study of the effects of different doses of tannery waste containing high amounts of organic substances, mineral elements and heavy metals on growth dynamics and metal accumulation in willow plants. Scions of Salix alba L., clone S61-02, were grown in the open near Pisa (Italy), in pots filled with a natural soil. Willows were pruned for a unique shoot ...
