Influence of the construction processing the multilayer lightweight concrete beam behaviour

Abstract

When a multilayer concrete beam is built, several concrete

mixtures could be poured sequentially. Usually concrete used

in external layers are higher resistance than those placed in

internal layers. Time between the pouring of the different layers

could have influence on the beam behaviour. The goal of this

paper is to study how temporary offset on manufacturing the

multilayer concrete beams has influence on their mechanical

behaviour.
