Diferencias de comportamiento entre un hormigón convencional y un hormigón ligero = Behaviour differences between a Normal Concrete and a Lightweight Concrete

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.
