<p>Foam concretes (FCs) offer notable advantages, including a high strength-to-weight ratio, excellent thermal insulation, good sound insulation, and improved fire resistance, due to their cellular microstructure. The production of FC for both structural and non-structural applications is influenced by factors such as foam stability, water-to-cement ratio (w/c), sand-to-cement ratio (s/c), and foam volume (FV), which individually or in combination, affect the compressive strength and density of FCs and hence, becomes the principal focus of this study. In this study, foam stability was evaluated through density and drainage tests on dilution ratios of 1:20, 1:30, and 1:40, with foam air pressures ranging from 294 to 588 kPa. Additionally, the effects of varying w/c (0.35, 0.40, and 0.45), s/c (1.0 and 1.5), and foam volumes (0, 10, 20, 30, 40, and 50%) on FC hardened density and compressive strength were examined across 36 different mixtures. Results indicated that foam stability improves with lower dilution ratios; however, high stability does not necessarily ensure compliance with ASTM C796 density criteria. Traditional influences of w/c and s/c on compressive strength were observed up to a foam volume of 30%. Beyond this threshold, the impact of the w/c diminished, suggesting that other factors become more dominant. Notably, foam volume emerged as the most significant factor, reducing hardened density and compressive strength by 3.2 to 46.5% and 10.2 to 94.1%, respectively, as foam volume increased from 10 to 50%. Contour plots further demonstrated the necessity for carefully optimizing the w/c, s/c, and foam volume to achieve the desired strength and density for various applications.</p>
