Comparison of lightweight and normal-weight aggregate concrete
DÜMF Mühendislik Dergisi, 2022 In this experimental study, lightweight aggregate concrete (LWAC) and normal-weight aggregate concrete (NWAC) were compared within the contexts of the size of calcium hydroxide (CH) crystals in interfacial transition zone (ITZ), compressive strength, and oven-dry density. Six LWAC and NWAC mixtures were prepared for this study.

A Plastic-Damage Model for Lightweight Concrete and Normal Weight Concrete [PDF]
International Journal of Concrete Structures and Materials, 2008 A new plastic-damage constitutive model applicable to lightweight concrete (LWC) and normal weight concrete (NWC) is proposed in this paper based on both continuum damage mechanics and plasticity theories. Two damage variables are used to rep- resent tensile and compressive damage independently.
