Decorative plate made of Nano concrete with High-Energy Mixing (HEM) Two-layered pavers, pigmented top layer made of HEM nanoconcrete Nanoconcrete (also spelled nano concrete or nano-concrete) is a form of concrete that contains Portland cement particles that are no greater than 100 μm [1] and particles of silica no greater than 500 μm, which fill voids that would otherwise occur in normal ...
Ange- Therese Akono's group studying the behavior of concrete directly at the nanometer lab scale, their trying to understand different structural property relationships. [ 11 ] In the development of smart cement, Akono suggested that longer, lasting material could save tax players billions in repairs and help reduce the carbon footprint.
Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material. [2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. [3]
Hence the inventors have also named it as 'Nano Concrete'. While it is possible to develop a strength of 20-30 MPa in conventional concrete with 320 kg of OPC per cu.m of concrete, for the same cement input Nano Concrete can render 50-80 MPa strength depending on fly ash quality and water input.

It has been suggested for areas including energy supply and storage, communication, transportation systems, construction and medical technology. Their electrical properties may allow energy to be transferred efficiencies approaching 100%. Nanotrusses may be eventually applicable for building materials, replacing concrete or steel. [8] [9]
Concrete is, after all, a macro-material strongly influenced by its nano-properties and understanding it at this new level is yielding new avenues for improvement of strength, durability and monitoring as outlined in the following paragraphs Silica (SiO2) is present in conventional concrete as part of the normal mix.
C-S-H is a nano sized material [5] [6] with some degree of crystallinity as observed by X-ray diffraction techniques. [7] The underlying atomic structure of C-S-H is similar to the naturally occurring mineral tobermorite. [8] It has a layered geometry with calcium silicate sheet structure separated by an interlayer space.
Franz-Josef Ulm (born March 9, 1964 [1] in Fürth/Bavaria, [2] West Germany) is a structural engineer, an engineering scientist and a professor since 1999. [5] He is Professor [1] [6] of Civil & Environmental Engineering [1] [5] at the Massachusetts Institute of Technology (MIT), [5] [6] [7] the Faculty Director [6] [7] of the Concrete Sustainability Hub (CSHub@MIT).
