Structural response of lightweight ferrocement panels (FPs) as low cost, durable, thin engineering elements was evaluated. Specifically, 21 FPs incorporating different contents of lightweight expanded clay (leca) (i.e. 40, 20, and 10 vol%) and perlite (i.e. 55, 35, and 15 vol%) aggregates and different number of expanded rib lath (ERL) …
