The effect of simulated ambient conditions on durability of concrete

open access: yesИнженерно-строительный журнал, 2020
This study aimed to assess the impact of ambient conditions on the internal microstructure of high-strength concrete (HSC) samples. A scanning electron microscope (SEM) was used with X-ray microanalysis to study the relationship between ambient conditions and the durability of concrete.
