| | Summary: |
| | Research on the application of nano materials in cement composites in the
world began in the early 21st century. When preparing UHPC, nano SiO2 was used. The
aim of the research is to determine the influence of nano-silica, as partial substitution
for cement on the mechanical properties of UHPC. The results of the comparative
testing of concrete in fresh and hardned state are presented without any substitution of
up to 2% of cement with nano SiO2. In order to determine the effect of the nano-silica on
the increase in compressive strength and flexural strength, the specimens which were
curing in water were tested at the age of 2, 7 and 28 days. |
