"The fundamental properties of concrete for use in outdoor environments is its resistance to weathering and stress resistance no strength effects. To measure the ability to withstand the combination of these effects has been established by freeze-thaw resistance. It is known that the freeze-thaw resistance is given particular quantity, shape and size of pores that are contained in the concrete. Their number and size can be influenced. They are mainly air entraining agent that can create a matrix of concrete closed spherical pores. This paper describes the properties of concrete based on alkali activated fly ashes (POPbeton) depending on the quantity of air entraining agent. There are described POPbeton features such as air content in fresh POPbeton, spacing factor and the freeze-thaw resistance."@en .
