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.

PERFORMANCE EVALUATION OF STRUCTURAL

2019-4-21  Many trials were carried out to produce the structural lightweight concrete using aluminum powder and pumice stone together; to get the best mixture that can resist fire. Selected mixtures are used to block heat transferring within the concrete and give the longer age of fire resistance. Pumice is used with different replacement values (0, 25, 50, 75 and 100%) of normal coarse aggregate (dolomite) by volume. Aluminum powderwas used by 0.5% of the cement weight to get suitable voids within concrete

Compressive strength evaluation of structural lightweight ...

2013-7-1  Highlights Results for wave propagation in lightweight concrete (LWC) are presented. The compressive strength of LWC is assessed by the ultrasonic pulse velocity (UPV). The influence of different mix design parameters is analyzed. A simplified expression to estimate the compressive strength from UPV is suggested. High correlation coefficients are obtained, regardless the concrete composition.
