The result indicates that the steel concrete which contains GGBS reduces the sulphate attack compared with the control mix .when compared to acid and alkali attack steel concrete shows better durability properties. this may be due to the presence of steel slag in concrete mix steel slag present in the mix reduce concrete permeability and make
2019-3-26and concrete also the use of the SCMs has always resulted many advantages like increases in durability of concrete and reducing impact on the environment by reducing green house effect. Nano particles as Nano silica are produce from silica sand. Some research on concrete are done for improving workability and strength of the concrete or mortar
2019-1-25B. Ground -Granulated Blast Furnace Slag Ggbs process a glassy granular product is obtained and then dried and grinded into fine powder. Ground granulated blast furnace slag GGBS is a off-white cementitious material. In mid 1800s the GGBS has been used all over the world and it is discovered by Emil langin. It is also
Concrete production is directly proportional to the cement content used in the concrete mix 900 kg of CO 2 are emitted for the fabrication of every ton of cement1. The usage of cement can be reduced by using the other possible cementing materials without compromising the strength and durability
Concrete is most extensively used material in construction. CO2 is emitted during the manufacture of cement damaging the environment. By lowering cement usage leads to reduction of CO2 generated. The increasing demand for cement made researchers to
2020-5-22The utiliation of supplementary cementation materials is well accepted since it leads to several possible improvements in the concrete composites as well as the overall economy. The present paper is an effort to quantify the strength of ground granulated blast furnace slag GGBS at various replacement levels and evaluate its efficiencies in concrete
Strength and durability studies of SCC incorporating silica fume and ultra fine GGBS. Incorporating 10 silica fume gave the best result in both mechanical and durability studies in comparison with other combinations. The durability of concrete with SCM was improved due to the poolanic reaction which occurs during the process of

2016-4-23splitting tensile strength and flexural strength respectively in comparison with the control mix. The bond strength were also comparable to the control mix. The durability studies showed that geopolymer concrete are less porous and more compact. Key Words Geopolymer Flyash GGBFS 1. Introduction In 1978 Davidovits proposed that a binder
2019-7-19GGBS was found to produce an optimum strength of concrete Oner and Akyu 2007. The corrosion resistance mainly due to chlorine durability and binding power of concrete is improved by using GGBS. It modifies the pore structure of concrete and results in a more hardened concrete and also abrasion resistance Rao et al. 2016. The
2015-12-4BEHAVIOUR OF SELF COMPACTING CONCRETE MADE WITH GGBS 1.11 Durability Studies of Low Medium and high grade SCC Mixes with GGBS and RHA. 18 mix of low medium and high strength concrete using chemical admixtures. The mix proportion was designed based on EFNARC method of SCC mix design.
2018-7-3that inclusion of high volume of GGBS in concrete increases the durability and found to be beneficial construction material Key words GGBS Compressive strength Impermeability Sulphate attack Acid attack. Cite this Article Anand V.R and Dr. A.V. Pradeep Kumar Durability Studies on

2018-7-19Compressive strength of concrete mixtures made with and without GGBS was determined at 7 14 28 63 119 180 and 365 days of curing. The average of six samples was taken for every testing age .It was observed that the early age strength values of GGBS concrete
2016-9-9GGBS is a better option since it has a higher proportion of the strength-enhancing calcium silicate hydrates CSH and is routinely specified in concrete to provide protection against both sulphate attack and chloride attack. So this study examined the potential use of sugarcane bagasse ash and GGBS as a partial cement replacement material. II
2013-3-690 days and the strength of the exposed specimens was found to be 54 and 41 less than bath and sealed specimen strengths respectively at 365 days. The early age strength development up to 28 days of GGBS blended concrete had found to be increasing with curing temperature but the effect on later strength is very less 3-5
2020-1-221. Durability and service life are improved by preparing High-performance concrete 2. The use of GGBS is economical in concrete. 3. The strength of compressive strength is increases 9 to 25. 4. It is easy to use and mix with concrete
2018-8-13the same strength as conventional concrete. The durability of concrete was done by curing with 5 Hydrochloric acid HCL and 5 Sulphuric acid H 2 SO 4. The effect of acids on compressive strength Split tensile strength and durability characteristic property was
2017-10-10normal-strength concrete and high-strength concrete by changing WB from 65 to 35 were examined. The effectiveness of GGBS on chloride ion diffusion coefficient was investigated by migration test. Moreover the application of GGBS which has the surface area of 6000 cm2g for bridge superstructures was presented
