Application of ANN for prediction of chloride penetration resistance and concrete compressive strength

Osama Mohamed et al.

Summary: Self-consolidating concrete has advantages over traditional concrete, but corrosion of steel reinforcement remains a major issue. The study successfully developed Artificial Neural Networks for predicting chloride penetration levels and compressive strength of SCC mixes. The trained ANNs showed promise in accurately predicting chloride penetration levels and compressive strength based on selected input parameters.

Effects of initial SiO2/Al2O3 molar ratio and slag on fly ash-based ambient cured geopolymer properties

Ayoub Dehghani et al.

Summary: This paper discusses the impact of SiO2/Al2O3 ratio and replacement materials on the properties of fly ash-based geopolymers. Results show that increasing the SiO2/Al2O3 ratio accelerates the setting of geopolymer systems but may lead to a peak and subsequent decrease in compressive strength. Furthermore, reducing the amount of replacement materials prolongs setting time and significantly reduces compressive strength.

Degradation of Alkali-Activated Slag and Fly Ash Mortars under Different Aggressive Acid Conditions

Jie Ren et al.

Summary: This study experimentally investigated the degradation of alkali-activated slag/fly ash mortars with different ratios exposed to acidic environments, finding that phosphoric acid had the greatest aggressivity and mortars with a 60/40 slag/fly ash ratio exhibited the highest resistance. The degradation process of alkali-activated mortars was divided into two stages, with theoretical analysis predicting significant reduction in degradation depth compared to ordinary Portland cement-based mortar.
