Self-compacting lightweight concrete produced with expanded clay aggregate
Highlights ► The self-compactability of lightweight aggregate concrete (SCLC) is analyzed. ► Permissible limits for the SCLC formulation are suggested. ► It was possible to produce SCLC with 490–599kg/m3 of fines content. ► SCLC compressive strengths of 37–61MPa and density classes D1.8–D2.0 are covered. ► It is found that SCLC can perform better than normal vibrated lightweight concrete.
Abstract The objective of this paper is to characterize self-compacting concretes produced with lightweight aggregates (SCLC) available in the Iberian Peninsula. The influence of different compositions on the self-compactability of SCLC is analyzed and some limits are suggested for their formulation. The usual self-compacting tests and additional segregation tests were considered. SCLC of adequate stability and self-compactability could be produced for compressive strengths between 37.4 and 60.8MPa, density classes D1.8–D2.0 and 490–599kg/m3 of fines content with 33% fly ash by weight. Promising results were obtained in the SCLC mechanical characterization.
