Nanotechnology in Civil Engineering

Nanotechnology can be used for design and construction processes in many areas since nanotechnology generated products have many unique characteristics. These characteristics can, again, significantly fix current construction problems, and may change the requirement and organization of construction process. To enhance properties of material used in construction. To satisfy the general aspect of people wanting more quality, control & reliability. To reduce cost of constructing structures.

Concrete is one of the most common and widely used construction materials. Nanotechnology is widely used in studying its properties like hydration reaction, alkali silicate reaction (ASR) and fly ash reactivity. With the addition of nano-SiO2 part of the cement is replaced but the density and strength of the fly-ash concrete improves particularly in the early stages. Fiber wrapping of concrete is quite common today for increasing the strength of pre-existing concrete structural elements.

Sustainable Materials and Construction

What is sustainable construction? It is the adoption of materials
and products in buildings and construction that will require less use of natural resources and increase the reusability of such materials and products for the same or similar purpose, thereby reducing waste as well.

Sustainable construction also enhances the resilience of the industry as such materials are readily available in the world market. Steel, other metals, glass and
prefabricated parts using combinations of these, as well as recyclable substitutes for concrete are examples of sustainable materials and products.

Ground Penetrating Radar - GPR

Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the underground surface for utilities or infrastructure. This nondestructive method uses electromagnetic radiation in the microwave band UHF/VHF frequencies of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of industries, where scanning can include rock, soil, ice, fresh water, pavements and structures.

In the right conditions, engineers can use GPR to detect objects under the ground such as electrical, water or gas lines, changes in material properties, and voids and cracks.

GPR has many applications in a number of industries. Within the Earth sciences it is used to study bedrock, soils, groundwater, and ice. It is of some utility in prospecting for gold nuggets and for diamonds in alluvial gravel beds, by finding natural traps in buried stream beds that have the potential for accumulating heavier particles. Before you dig or core make sure you have a qualified company GPR the subsuface.
