In order to study the mechanical properties of stud connectors in lightweight aggregate concrete (LWAC), finite element software ABAQUS was used establish push test models ordinary and LWAC, respectively. Through parameter analysis 21 models, influence different parameters on shear performance LWAC connector studied. Among them, strength, diameter strength have strong effects. Compared with con...

In this study, a fuzzy logic prediction model for 3, 7, 14 and 28 days compressive strength of lightweight concrete made with scoria aggregate and fly ash under different curing conditions (standard and air curing) was devised. In mixtures containing fly ash, 15% of Portland cement by weight was replaced with fly ash. The specimens were cured in standard curing conditions at temperature 20±2 °C...
