TL;DR: In this paper, the coupled effect of temperature and silica fume addition on rheological, mechanical behaviour and porosity of grouts based on CEMI 42.5R, proportioned with a polycarboxylate-based high range water reducer was investigated.

TL;DR: The use of randomly distributed steel fibres in the concrete mix improves the mechanical properties of flat slab-column connection as mentioned in this paper, which can provide slabs with an increased load capacity and deformation capacity, allowing a potential reduction of reinforcement.

TL;DR: In this paper, the authors study the behavior of reinforced concrete flat slab structures under combined vertical and horizontal cyclic loading and show that cyclic horizontal actions are very harmful to the slab-column connection, resulting in low horizontal drifts and energy dissipation.

TL;DR: In this article, the experimental analysis of reduced scale flat slab models under punching, subject to in-plane forces is described and the results are compared with the Eurocode 2 (2004) [1] provisions, the FIP Recommendations for the Design of Post-tensioned Slabs and Foundation Rafts (1998) [2] and ACI 318-08 (2008) [3], to evaluate their validity.

TL;DR: In this paper, the punching behavior of high strength concrete flat slabs is investigated and the results show that the use of HSC led to a significant load capacity increase when compared with the reference model made with NSC.
