The characteristics of the compressive strength and splitting tensile strength according to replacement ratio of the blast furnace slag were found in this study. The blast furnace slag was utilizes as the concrete mix-material and then, these results were compared with the basis presented in the international standards. In this study, cylinder made of concrete with water/binder ratio 0.34 and blast furnace slag replacement rate of 10%, 30%, 50%, and 70% were prepared to measure the compressive strength and spiting tensile strength. Test results indicate that The 28 days and 91 days compressive strength is affected by blast furnace slag replacement except specimen BS30 and the splitting tensile strength in specimen BS series is slightly larger than that of OPC except specimen BS 30.

The shrinkage cracking of concrete plays an important role to the accelerated deterioration and shortening the service life of concrete structures. The mineral admixture will be a perfect component of high performance concrete and its utilization will be a valuable resource for recycling. Early age cracking characteristics of concrete with compound admixtures, such as steel slag, blast furnace slag, fly ash, are studied in this paper using plate test method. The better anti-cracking performance of concrete will be realized when blast furnace slag replacing cement at 30%, steel slag and fly ash as the equal mixture components replacing cement at 30%, three kinds of admixtures replacing cement at 30% under the proper proportion.

Fly ash and blast furnace slag dumped not only pollutes environment, but also consumes landfills. With the aim of sustainable development, the isolated contribution of fly ash and blast furnace slag in concrete to the mechanical properties of frame concrete is investigated. An experimental study is conducted to investigate mechanical properties of high performance concrete. Test variables are the replacement levels for FA series (10%, 20% and 30%) and for BS series (10%, 30%, 50% and 70%) in place of part of cement. Compressive, splitting tensile strength, modulus of elasticity and flexural strength tests were carried out to evaluate the mechanical properties for up to 7days and 28 days. The mechanical properties of high performance concrete compared with predicted values by ACI 318-02 Code, EC 2-02, JSCE Code, KCI Code and proposed Eq.

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).
