DOI: 10.1007/s11242-018-1182-3
Abstract: Many concrete structures located in cold climates and in contact with free water are cast with air-entrained concrete. The presence of air pores significantly affects the absorption of water into the concrete, and it may… read more here.

DOI: 10.3390/ma16072752
Abstract: It is well known that the most important parameters for predicting the frost resistance of pavement concrete are the air pore spacing factor, L, and the micropore content, A300. The A300 parameter requires complex calculations… read more here.
