Title: An Investigation of Steam Curing Pressure Effect on Pozzolan

            Additive Autoclaved Aerated Concrete

Authors: Kadir Güçlüer, Osman Ünal, Ismail Demir, M.Serhat Baspinar


Autoclaved Aerated Concrete (AAC) is a porous light weight concrete obtained by adding a pore-forming material to a mixture made of finely  pulverized siliceous aggregate and inorganic binder (lime and/or cement) and hardened by steam cure.  In this study fly ash was used instead of siliceous aggregate and experiment samples were obtained by adding 3%, 6%, 9%, 12% silica fume to the cement. Samples were cured under 1560C and 4 bars and 1770C and 8 bars, and were investigated for compressive strength, bulk density and ultrasound pulse velocity to determine their mechanical and physical properties.  Microstructure of samples was observed by using SEM and XRD techniques. Samples’ bulk density values and compressive strengths are changing between 0.6-0.7 kg/dm3 and 2.5-4.4 MPa respectively.

Keywords – Aerated concrete, Pozzolan, Cure.
