The use of raw and calcined diatomite in cement production
Bülent Yılmaz,Nezahat Ediz +1 more
TL;DR: In this article, the use of raw and calcined diatomite which is in amorphous and porous nature was investigated in cement production, and the physical, chemical, mineralogical, micro-structural and mechanical tests of the mortars were carried out.
Journal ArticleDOI
Characterization of lightweight aggregates manufactured from washing aggregate sludge and fly ash
TL;DR: In this paper, the effect of raw material characteristics, heating temperatures and dwell times on loss on ignition (LOI), bloating index (BI), loose bulk density (π b ), apparent and dry particle density ( ρ a, ρ rd ), voids (H), water absorption (WA 24h ), and compressive strength (S ) had been determined.

Lightweight aggregates from waste materials: Reappraisal of expansion behavior and prediction schemes for bloating
Michele Dondi,Piergiulio Cappelletti,M. D’Amore,R. de Gennaro,Sossio Fabio Graziano,Alessio Langella,Mariarosa Raimondo,Chiara Zanelli +7 more
TL;DR: In this article, a new approach to assess the batch expandability was developed through a deeper comprehension of mechanisms acting on sintering and expansion of lightweight aggregates (LWA) for recycling of waste materials: the main challenge for this purpose is the control on the technological behavior during firing of waste-bearing batches.

Geotechnical Properties of Innovative, Synthetic Lightweight Aggregates
TL;DR: In this paper, a major concern with respect to sustainable infrastructure development is the continued depletion of easily-available natural resources; e.g., construction aggregates; however, current economic, political and environmental factors limit the access to the reserves.
