Caracterización mecánica experimental de un hormigón ligero estructural = Experimental mechanical characterisation of a structural lightweight aggregate concrete

摘要

The self load of the structure is usually similar even bigger than any other load load which a structure carries. Due to this fact a number of structure are inefficient. The replacement in concrete of normal aggregate by lightweight aggregate reaches a markedly reduction of the concrete weight. The mechanical behavior of a lightweight aggregate concrete is analyzed in this paper. A number of tests have been done at different ages. These results have been compared with the predicted mechanical values of some regulation
