Evaluation of Foamed Concrete Properties Containing Engineered Pozzolans and Compressive Strength Prediction Through Artificial Neural Networks

International Journal of Concrete Structures and Materials
The performance of foamed concrete (FC) is significantly influenced by the type and proportion of supplementary cementitious materials (SCMs). However, comprehensive studies investigating the combined effects of engineered pozzolans on the thermal ...
