Lightweight self-compacting concrete reinforced with fibres for slab rehabilitation

Blog Article

The slabs of some buildings in Barcelona are formed by unidirectional beams, with a ceramic arch in between, which are filled with broken pottery or construction waste.These structures often present problems such as displacement of the tiles arranged over it due to the lack of stiffness of the filling material.This supposes a risk to the user and could also cause steely dan gaucho t-shirt durability problems.In order to rehabilitate it, a lightweight self-compacting concrete reinforced with fibres (HLACF) has been designed to teucrium cossonii majoricum be used as a filling material, improving the stiffness of the structure.

This paper presents a structural analysis of a standard case and the results of an experimental campaign.The concrete showed a density of 1665 kg/m3, a slump flow of 605 mm and a compressive strength of 22.3 MPa, at 28 days.These results are in agreement with the requirements, overcoming common lightweight concrete segregation problems.
