The use of fly ash in concrete can lessen the burden of its dumping in landfills to protect the environment and soil degradation. We investigated the concrete mixtures incorporating various percentages of fly ash and studied the mechanical properties of h... see more

La resistencia a las heladas es una de las características más importantes que describen un elemento estructural de hormigón. En condiciones de procesos de congelación/descongelación frecuentes y repetidos, la estructura se debilita significativamente. Lo... see more

Indian standard Code-IS:456-2000 and Eurocode EC:02-2004 for the design of the concrete structure is limited to the concrete with compressive strength of 55 MPa and 90 MPa respectively. For defining the stress block parameters and for the design of concre... see more

In this paper, the behavior of hybrid short columns made from low strength reinforced concrete core and an outer skin made from high strength concrete was studied. For this purpose, laboratory tests were carried out on ten small-scale column specimens. Fo... see more

Research developed in the last decades has allowed significant advances in the concrete technology, achieving remarkable improvements in its performancemainly related to its microstructure. In order to relate the behaviour under compressive stresses of hi... see more

 In this paper, four concrete frame joints with high-strength stirrups and one with normal-strength stirrups were tested to investigate the mechanical properties of concrete beam-column joints with high-strength stirrups under low cyclic reversed loa... see more

High strength concrete (HSC) define as the concrete that meets a unique mixture of performance uniformity requirements that cannot be reached routinely using conventional constituents and regular mixing, placing, and curing events. The modeling of such ty... see more
