C. Flexural Strength

The implicit measure of the stiffness of unreinforced concrete is the modulus of rupture, also referred to as the flexural strength of concrete. Instead, the modulus of rupture can be characterised as a measurement of the excessive fibre stresses when a member is bent. Together with external force, other factors such as warping, steel corrosion, drying shrinkage, and temperature gradient can also cause tensile stresses.

IV. CONCLUSION

GPC that uses by-product materials is highly sought after for more environmentally friendly construction. The goal of this study was to improve the qualities of high-strength ecologically friendly concrete by adding MBS and GGBS to the mix. The main goal of this experimental inquiry is to ascertain the effects of mixing MBS with various amounts of concrete and mortar that have been alkali activated using slag.

Also to determine the effects of MBS inclusion on the final product, which included testing various amounts of slag-based alkali activated mortar and concrete,

1) From the process used, it can be deduced that the geopolymer mix with 90% GGBS and 10% MBS has a compressive strength that is 22.41% higher than regular portland cement.

2) Because of the replacement materials' ability to bond, it has been found that when the amount of micronized biomass increases gradually, silica gradually loses some of its mechanical qualities.

3) Comparing the observed concrete to regular portland cement, the split tensile strength is 37.75% higher.

4) When the findings for compressive strength, split tensile strength, and flexural strength are compared to those of regular portland concrete, the results for geopolymer concrete with ground granulated blast furnace slag and micronized biomass silica are found to be greater.

5) For all specimens, the concrete's ability to absorb water is below the limit, indicating high concrete quality. By adding micronized biomass silica, the chloride ion penetration is also successfully resisted.

6) In conclusion, this developed GPC mix has been proven to be promising for use in a variety of constructions, including loadbearing, concrete highway, and non-load bearing structures.
