The use of industrial waste and/or by-products as alternative sources of raw materials in
building materials has become standard practice. The result, more sustainable construction …

Lightweight expanded clay aggregate (LECA) is a manufactured aggregate with many uses
in construction, such as aggregate for the lightweight concrete or like geotechnical fill. The …

Nine clays traditionally used in the ceramic brick and tile sector in Southern Europe were
evaluated for the production of lightweight aggregates: four from Spain, three from Portugal …

The compositional synergies involved in the thermal formation of lightweight aggregates
(LWAs) have been investigated through four pure phases: non-expansive kaolin (K); cork …

The current environmental problems that threaten our society can only be mitigated with a
radical change in the paradigm of production and consumption. Recycling waste is a key …

The use of carbon fiber wastes (FC) as a component to manufacture lightweight aggregates
(LWAs) for concrete has been studied. Amounts of 0, 2.5, 5 and 10%(w/w) of powdered FC …

Four organic solid wastes (coffee grounds, ground nut shell, paper money sewage sludge
and cork powder) have been investigated as bloating inducing agents in lightweight …

Lightweight aggregate bloating process has been studied by a simple experiment using an
archetypal clay to know the actual amount of gas involved in expansion. Considering the …

Mining activity can release important amounts of toxic metals which are able to move
through the soil, water and air, or even to reach the human food chain. Consequently, the …

The effect of the addition of Fe0 and Fe3+ on the formation of expanded clay aggregates
was studied using iron-free kaolin as an aluminosilicates source. Likewise, the incorporation …
