Le béton à hautes performances (BHP) est un béton innovant largement utilisé dans la construction moderne. De nouvelles techniques de formulation et de conception du HPC ont permis d'obtenir des performances mécaniques et une durabilité remarquables par rapport au béton conventionnel. Les principaux avantages du HPC sont liés à sa faible porosité, sa très haute résistance mécanique et son excellente durabilité. La facilité d'application du HPC est obtenue par l'utilisation combinée de superplastifiant et d'ajout de minéraux, ce qui se traduit par une augmentation significative de la résistance à la compression tout en améliorant la maniabilité et la durabilité. L'utilisation d'un liant ternaire (ciment, fumée de silice et laitier granulé de haut fourneau broyé) dans la fabrication du HPC est une nouvelle avancée dans la construction durable qui offre des avantages économiques, techniques et écologiques. L'objectif de ce travail de recherche était d'améliorer les propriétés physico-mécaniques du HPC à base de liant ternaire en étudiant l'influence du remplacement du ciment par du laitier granulé et des fumées de silice. Les résultats des tests mécaniques montrent que les performances du HPC réalisé avec ces liants ternaires sont similaires au HPC témoin sans laitier granulé. Enfin, il est conclu que l'utilisation de tels liants est très bénéfique pour diminuer les problèmes environnementaux et améliorer la durabilité du HPC.

Strength, ductility of structures differ primarily on appropriate detailing of. beam column joints need a vital role in the structural reliability of the structures given with appropriate stiffness and ultimate strength to maintain the loads transmitted from beam and column. Beam column joints defined as the reinforced concrete buildings, in which portion of columns and beams having their intersections. Although these forces greater than these are affected during earthquakes, joints are relentlessly damaged. As far as earthquake is affected, research on beam-column joint is essential. In HPC, these materials with admixtures are meticulously designated and proportioned to produce very high early, ultimate strengths and durability away from conventional concrete. The admixtures like flyash, silicafume, ground granulated blast furnace slag (GGBFS), which are combined with its strength and durability and boost its marketability as a natural friendly product. The most important purpose of the present study is to investigate the performance of high performance reinforced beam-column joints (replacement of cement with GGBFS). Ground granulated blast furnace GGBFS is employed as a partial replacement of cement with glass fibre and super plasticizer is applied to accomplish required workability. In this study, a evaluation of control specimen and specimen of beam column joint with 7.5% GGBFS and 0.3% glass fibre replacement intended as per IS 456:2000 and IS 13920:2016. Also, to ascertain the performance of beam-column joints subjected to monotonic loading for high performance concrete employing with Ground Granulated Blast Furnace Slag (GGBFS) and glass fibre.

This paper addresses the results of an extensive experimental study on the compressive, splitting tensile strength modulus of elasticity in long-term. These tests were carried out to investigate the mechanical properties of HPC for 56 and 91days. In this work, High performance concrete was designed a water-binder ratio of 0.40. In addition, three different concrete mixes were used in these specimens. The results properties of HPC with fly Ash, blast furnace slag and silica fume were effective for compressive strength splitting tensile strength and modulus of elasticity improvement between 56 to 91 curing days.

This paper reports an experimental study of the influence of finely ground-granulated blast-furnace slag (GGBS) used as partial substitute for Portland cement (PC) on the mechanical properties and durability of high performance concretes. The analysis of the experimental results on concrete at 17.5% content of blast furnace slag with a fineness modulus of 8500 cm2/g, in a chloride environment, showed that it contributes positively to the perfection of its mechanical characteristics, its durability with respect to water absorption and migration of chloride ions. On the basis of the experiments performed, it can be concluded that the GGBS is suitable for formulation of high performance concretes (HPC) and their properties are significantly better compared to the reference concrete (RC).

This article deals with influence of the ground granulated blast furnace slag (GGBS) in the mixture of high performance concrete. It is a powder active addition used in concrete which is characterized certain cementitious properties. Influence of this addition was experimentally verified. In the first series, partial replacement of cement by GGBS was tested. In the second series, GGBS was added to the original reference mixture. Studied parameters were compressive strength, tensile strength and workability. The tests have shown that a partial replacement of the cement by GGBS is possible for achieving the desired workability or if we need to reduce the price of concrete.

High performance concrete (HPC) can be made with cement alone or any combination of cement and mineral components, such as, blast furnace slag, fly ash, silica fume, kaolin, rice husk ash, and fillers, such as limestone powder [. In this study, three mixes of high performance concrete (HPC) with same water-binder ratio and different types of mineral admixtures were prepared. he compressive strength, splitting tensile strength and modulus of elasticity values were measured in accordance with the ASTM. The influence of fly ash (FA), blast furnace slag (BS) and silica fume (SF) on mechanical properties of HPC were compared and analyzed. Their mechanical properties are measured at 7 days and 28 days. The results showed that specimen BS45+SF5 performed better than specimens BS30+FA25+SF5 and BS65+SF5 for the compressive strength, splitting tensile strength and modulus of elasticity.
