Optimising dosage of Lytag used as coarse aggregate in lightweight aggregate concretes
Journal of the South African Institution of Civil Engineers, 2013 Lytag, manufactured first by pelletisation of a mixture of fly ash, bentonite and water, and then by sintering the spherical pellets at about 1 300°C, is used as coarse aggregate for producing lightweight plain and structural concrete mixtures.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.
