Drying shrinkage properties of expanded polystyrene (EPS) lightweight aggregate concrete: A review
Maghfouri, Mehdi; Alimohammadi, Vahid; Gupta, Rishi; Saberian, Mohammad; Azarsa, Pejman; Hashemi, Mohammad; Asadi, Iman; Roychand, Rajeev (Peer reviewed; Journal article, 2022)Expanded polystyrene (EPS) is currently being utilized in sustainable materials owing to its ultra-low density and superior thermal performance. It can be incorporated in concrete mixtures to replace coarse aggregate to ... -
Evaluating the effective thermal conductivity of cement mortar through x-ray scanning
Asadi, Iman; Ji, Guomin; Haj Mohammadian Baghban, Mohammad (Peer reviewed; Journal article, 2022)The effective thermal conductivity of cement mortar as a porous material depends on its solid phase and void phase conductivity. Therefore, a sample's pore distribution can highly impact the value of effective thermal ... -
Evaluating the time lag and decrement factor of mortar and concrete containing OPBC as an agricultural by-product lightweight aggregate
Asadi, Iman; Hashemi, Mohammad; Sajadi, Behrang; Mahyuddin, Norhayati Binti; Haj Mohammadian Baghban, Mohammad; Esfandiari, Masoud; Maghfouri, Mehdi; Yan, Kezhen (Peer reviewed; Journal article, 2023)Replace the normal weight aggregate with wastes or by-products materials is an appropriate method for producing a sustainable cement-based material. The replacement helps to have an energy-efficient component that reduces ... -
A field study on thermal comfort and cooling load demand optimization in a tropical climate
Esfandiari, Masoud; Zaid, Suzaini Mohamed; Ismail, Muhammad Azzam; Hafezi, Mohammad Reza; Asadi, Iman; Mohammadi, Saleh (Peer reviewed; Journal article, 2021)Energy consumption to cool an indoor environment is a substantial part of total energy end-use, particularly in a tropical climate with high energy demand for cooling. To improve energy efficiency, cooling systems can be ... -
FROST TESTING NON-AIR ENTRAINED SUPPLEMENTARY CEMENTITIOUS MATERIALS HIGH PERFORMANCE CONCRETE: SALT-SCALING AND INTERNAL DAMAGE
Jacobsen, Stefan; Asadi, Iman; Skjølsvold, Ola; Kanstad, Terje (Chapter, 2023)Air-entrainment is difficult with high volumes of Supplementary Cementitious Materials (SCM). High Performance Concrete (HPC) with low w/b without air-entrainment can, however, survive severe deicer salt frost performance ... -
Macroporosity and water penetration measurements of sprayed concrete: Open vs closed macroporosity, size, shape, orientation and anisotropy
Hårr, Magne Stangeland; Kjeka, Gaute (Master thesis, 2022)Hensikten med oppgaven var å undersøke makroporøsitet og permeabilitet til sprøytebetong. Dette innebar å (1) undersøke åpen og lukket makroporøsitet målt med PF-metoden, (2) sammenligne luftinnhold i ulike betongtyper ... -
