Test Result

Geopolymer concrete plays a major role in concrete industry by replacing cement and using the industrial wastes. In this study, the cement is completely replaced by GGBS and strength properties are analyzed. An M30 mix design is prepared and the specimens are cast and tested. For this, sodium hydroxide and sodium silicate are used as activator and its ratio is fixed as 1:2.5. Sodium hydroxide of 12 molarity, 550kg/m3 of GGBS is used in the study. Admixture La Hypercrete S25 (HTS code 38244090) is added in the mix by 1% of weight of GGBS to obtain the required workability. For compression study, cubes in 100 mm size are cast. Cylinders with 100mm dia and 200mm height are tested for splitting tensile strength and beam specimens of 500mm long and 100mm cross sections were cast for determining the flexure behaviour. The beams are subjected to ambient curing and tested at 3, 7, 14, 28 and 56 days. The test result shows that there is a gradual increment in all the strengths from 3 to 56 days and it proves that geopolymer concrete with GGBS cured at ambient temperature performs well in the strength properties.

Geopolymer concrete is the concept of environmental friendly construction material which helps in reducing the greenhouse gas emission, however it cannot be applied directly on field due to its steam curing process. To overcome this defect various researcher have found self-curing or ambient curing process to achieve same strength as in steam curing process for geopolymer. This paper presents an over review about self-cured or ambient cured geopolymer concrete produced by various methods.

Abstract: In modern construction concrete is very expensive and popular material where cement is the main composite. Every year we are producing billion tons of concrete. Production of cement is responsible for too much of CO2 production, in other words it is also responsible for global warming. Mostly India is facing the problem of pollution. Researchers have done a great job and found many ways to replace cement. For making geopolymer concrete by products of different industries may be used like. Fly ash, rice husk. In this investigation geopolymer concrete is prepared with GGBS. GGBS is a by-product of steel industry. It holds the coarse and fine aggregates in the matrix. In this investigation geopolymer concrete is prepared with GGBS and advantages and disadvantages are also investigated. It was an observation that it has good results over other concrete. GGBS is a good replacement of cement and it will help in reducing the production of CO2. as a result of this global warming can be reduced. Keywords: GGBS, Slag, Aggregates, Slump, Geo Polymer
