    AbstractAn experimental study was carried out to examine five mixtures made with selected Brazilian lightweight aggregates in order to produce lightweight aggregate concrete (LWAC) for slim precast components. Flow (initial and after 2 h), air content, compressive strength, tensile strength (flexural and splitting), modulus of elasticity and deformation were studied. The 7-day compressive strength and the dry concrete density varied from 39.7 to 51.9 MPa and from 1460 to 1605 kg/m3, respectively. The results of this pilot study suggest that there are possibilities of producing slim precast components using high-performance lightweight concrete with Brazilian lightweight aggregates.
