Frame Bracing
Design of bracing to resist forces induced by wind, seismic disturbances, and moving loads, such as those caused by cranes, […]
Free Orifice Test
The free orifice test (Bartos 1992; Bartos 1994; Wong et al. 2000; Bartos, Sonebi, and Tamimi 2002) measures the time
Free Flow Test Methods
Free flow test methods are generally simple to perform and provide a clear, direct result. The slump test is the
Fractures due to stress corrosion cracking
The term `stress corrosion’ stands for the process of crack initiation and crack propagation under the influence of a specific
Fractures due to fatigue and corrosion cracking
Prestressing steels can only be subjected to a noticeable stress in dynamically strained reinforced concrete structures if the concrete is
Freeze-thaw in concrete Key factors
Four key factors of influence on deleterious freeze-thaw behaviour are the porosity/permeability, aggregate characteristics, moisture state and climatic conditions. In
Freeze-thaw in concrete Aggregate characteristics
Consideration of the factors influencing freeze-thaw behaviour involves considerable attention to the pore structure of the hardened cementitious matrix. However,

Freeze-thaw in concrete Moisture state
The volume expansion occurring on conversion of water to ice and associated water movement cannot be accommodated in fully saturated
Freeze-thaw in concrete Climatic conditions
Exposure conditions that represent the greatest threat to concrete in cold climates are those that combine a number of parameters.
