Silica nanoparticles appear to prevent premature deposition in the core and reduce freezing time, and the pozzolanic behavior of these nanoparticles improves the interaction between aggregate and cement paste. Another nanoparticle that supports the properties of concrete is titanium dioxide, which is also used in stained cement and window glasses due to its sterilizing properties and strong catalytic reactivity.

What is the grade of mortar?
Generally, nanoparticles act as crystallization centers and these small nanoparticle sizes make it easier to fill voids and voids and provide a greater effect on pores as filler and better adhesion between cement paste and aggregates. One of the desirable effects of using nanoparticles is to increase the chondronicity of the concrete dough before freezing, which improves the suspension state of the aggregate and increases the workability of the concrete. Nanotechnology and special concretes:
- 1 fiber concrete
- 2 self-compacting concrete
- 3 thermosetting smart nano-concretes
Nanoscience and nanotechnology, sometimes referred to as nano-improvement in concrete, are the titles used to describe two ways in nanotechnology research in concrete. The use of nanotechnology in the concrete industry has been based on recent years. The use of micron sized silica has been widely used in cement based concretes for nearly 80 years. The use of particles smaller than microsilica has been shown to increase the compressive strength of concrete. Nanoscience is concerned with measuring and explaining the structure of nano- and micro-scale cementitious materials to better understand macro behavior and performance using advanced atomic or molecular-level characterization and modeling techniques.
Nanotechnology includes nanometer-scale structure manipulation techniques to create new and suitable generation cementitious composites with ideal mechanical behavior, and even concrete with new properties such as low electrical resistance, smartness, self-cleaning, self-healing, high ductility. Brought to you. Recent research activities in nanotechnology in concrete include: the internal study of hydration in cement, the effect of adding nanosilica to concrete, the addition of nanoparticles to cement, concrete and cement-based coatings, and observing their effects on the behavior and properties created. A lot of research has been done on the application of nanotechnology in concrete structures. To understand this at the basic science level, technologies such as AFM, SEM and FIB microscopes have been developed for nanoscale studies.
