An Emphasis of Geopolymer Concrete with Single Activator and Conventional Concrete with Recycled Aggregate and Data Analyzing using Artificial Neural Network

Abstract

The emphasis of concrete in the advancement of construction industry is essential. Due to the rapid increase in the development of infrastructure, there is a considerable demand for the construction materials. The construction materials drained gradually due to continue use in construction and there is a degree for the advancement of these development materials. Therefore, in this context, a rapid increase in the price of conventional construction materials and various governments have put restrictions on fine aggregates. In this circumstance, the investigation attempted to determine the appropriateness of the substitute materials in concrete development because these materials are eas ily available at very low cost as compared to conventional fine and coarse aggregates. The effect of recycled aggregates on the strength of conventional concrete and Geo-polymer concrete was studied. The natural aggregates are replaced by the crushed aggregates of intervals of 10%,20%, 30%, 40 %, and 50% in both geo-polymer and conventional concrete. The different strengths of 20MPa, 40MPa, and 60MPa werestudied in this research work. The conventional concrete cubes were cured in normal water and geopolymer concrete cubes cured in ambient room temperature. The coarse aggregates used were of size 20mm and 10mm sieved and the recycled aggregates contains a cement mortar attached to it. The outcomes show that a slight decline in the strength of conventional concrete and high strength found with 30% substitution of coarse aggregate and eventually the prediction of data was analyzed using Artificial Neural Network

“…The R e t r a c t e d anticipated outcomes confirmed the suggested model's high levels of accuracy and predictability [45]. Other studies considered other soft computing methods on the geopolymer concrete [46][47][48][49]. In another study, based on ground GGBS, numerical models were created using GEP to estimate the f c of GPC.…”

Variation of sodium hydroxide concentration impact on rheological properties of geopolymer paste

“…After that, the mixture is weighed. Finally, an alkaline activator is made by adding an appropriate amount of sodium silicate solution (2.5 times the weight of sodium hydroxide solution) studied by Poloju et al (2020aPoloju et al ( , 2020b and Rao et al (2020).…”

Influence of GGBS and Alkaline Ratio on Compression Strength of Geopolymer Concrete

“…It is necessary to mix sodium silicate solution with sodium hydroxide solution 2.5 times, then store the mixed solution at 25°C and relative humidity of 65% for 24 hours before casting. An alkaline activator is prepared by adding sodium silicate solution, which is an adequate amount (2.5 times the sodium hydroxide solution weight) [18][19][20]. As NaOH reacts with water, a lot of heat is produced, so the heat must be reduced to an outdoor temperature before concrete can be added.…”
