Resumen Resulta paradojico que a pesar de las enormes ventajas que supone en muchas aplicaciones de construccion el empleo del hormigon ligero estructural (HLE) frente a un hormigon convencional (HC), su uso todavia no se haya generalizado. Muy posiblemente, el desconocimiento de su comportamiento fisico y mecanico contribuye de forma decisiva a la utilizacion de un HC en muchas ocasiones en las que su sustitucion por HLE seria totalmente competitivo y ventajoso. Este trabajo pretende ampliar el conocimiento del comportamiento del HLE para contribuir a su utilizacion en todas las situaciones en donde su empleo supone una clara ventaja frente al HC. Abstract It is a paradox that despite of the huge advantages of the Lightweight Concrete (LWC) over the Normal Concrete (NC) in a number of construction applications, its use has not been widespread. Quite sure, the lack of knowledge about LWC mechanical behavior leds to the use of NC in many occasion when a the use of LWC will be totally competitive and beneficial. This paper aims to expand the knowledge about LWC behavior to contribute to its use at any situation when its use is an obvious advantage against NC.
