Applications of using nano material in concrete
Eventually, the introduction of nano materials in concrete is to increase its strength and durability.
Reducing the formation of micro pores
Nano material is defined as material that contains particle size which less than 200 nm. For the purpose of concrete study, the application of nano materials must be at least 500 nm in size. The addition of ultrafine nano material will help to reduce the cement content by partially replacing cement on weight basis to improve the binding effect. The ultrafine particles of nano material will also help reduce the formation of micro pores by acting as a filler agent, producing a very dense concrete and automatically reduce the growth of micro pores in the UHPC structures.
The study is published in: Construction and Building Materials, Volume 133, 15 February 2017, Pages 91–97
