DOI: 10.1007/s12205-020-0793-8
Abstract: The factors associated with concrete carbonation can be classified in three major categories of environmental factors, concrete’s internal-structural factors, and construction-operation conditions. Climate change is expected to cause gradual change in many primary environmental factors,… read more here.
