CiteSeerX — Structural Evaluation of Lightweight Concrete ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The construction industry consumes a large amount of non-renewable resources. On the other hand, more waste paper ends up in landfill or dump sites than those recycled. Consequently, recycling waste paper for use as a construction material constitutes a step towards sustainable development.

Sorptivity, and Microstructure of Lightweight Concrete

Lightweight concrete (LWC), often utilized in structural and masonry elements, is a versatile construction material with reduced dry density and low thermal conductivity. Moreover, because of the lower thermal conductivity of LWC, compared with normal-weight concrete, LWCs with low densities are widely used as heat and acoustic insulating elements.
