] on the behavior of SF on the steel slag powdered concrete, a decline in the CS was observed beyond 8% of addition of SF, which is due to the fact that Ca(OH) 2 produced upon cement hydration was exhausted as a result of which no C–S–H gel could be
plasticity and fracture mechanics. The presence of cement hydrates results in microscopic fracture when cement-treated sands are subjected to load; The models suggested for plastic strain, fracture
analysis of the concrete structure, the numerical strategies are implemented considering the cement hydration, creep, shrinkage, and solar radiation for early age concrete. The objective is to document and hopefully verify a method of thermal analysis and
