Shrinkage and creep strains of concrete exposed to low relative humidity and high temperature environments

•Shrinkage of concrete is measured with various temperature and humidity conditions.•The fib MC2010 shrinkage model is accurate for low RH and high T conditions.•The fib MC2010 shrinkage model slightly underestimate for other conditions.•The fib MC2010 creep model conservatively predicts creep strai...

Description
Summary:•Shrinkage of concrete is measured with various temperature and humidity conditions.•The fib MC2010 shrinkage model is accurate for low RH and high T conditions.•The fib MC2010 shrinkage model slightly underestimate for other conditions.•The fib MC2010 creep model conservatively predicts creep strains. Creep and shrinkage of concrete is influenced by many factors including relative humidity and temperature. The combined effect of low relative humidity (
