Production of smart nanocement for greater strength of structures and roads
Nano
Researchers by entering Nanoparticles In ordinary cement, they produced smart, more durable and very efficient cement Nano smart cement The new one that the researchers made can be used to increase stability Roads and cities used. The forces of nature have been destroying these materials ever since we started producing them.. Ice and snow block major roads. The foundations of houses, despite their solid construction, crack and break down.
Engineers who address this issue with smart materials usually enhance the material's performance by increasing the amount of carbon, but doing so causes the material to lose some of its mechanical performance..
Quality control of nano products
Given that cement as The most widely used substance in the world It is known and cement industry It accounts for 8% of greenhouse gas emissions Nanoparticles It is not well understood in this area before; So, this is a big improvement. But the main challenge for mechanics is to know how to change the cement manufacturing process to increase the fracture response of this product.!؟
The researchers of this Project Using an innovative method called “scratch test“, in a fraction of time, they efficiently make predictions about material properties. In this method, they test the fracture response by using a cone probe with increasing vertical force compared to the surface of the microscopic bits of cement..
Technical inspection of nano products
Predictions made through scratch tests to Engineers It allows them to make changes to materials that increase their performance on a larger scale. In this article, graphene nanoplatelets were used to improve the fracture resistance of conventional cement. Combine a small amount of this Nanomaterials It was also effective for improving water transfer properties, including pore structure and resistance to water penetration, a relative reduction of 76 and 78% was reported for these two factors, respectively..
Nanomaterials Carbon-based including graphene nanoplatelets are currently in the design of smart cement-based sensors for Supervision are considered on structural health.
