摘要
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 60.8 MPa, density classes D1.8-D2.0 and 490-599 kg/m(3) of fines content with 33% fly ash by weight. Promising results were obtained in the SCLC mechanical characterization. (C) 2012 Elsevier Ltd. All rights reserved.
