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 ...
Start downloading a Wikipedia database dump file such as an English Wikipedia dump.

Among the new nanoengineered polymers, there are highly efficient superplasticizers for concrete and high-strength fibers with exceptional energy absorbing capacity. [ 10 ] Experts believe that nanotechnology remains in its exploration stage and has potential in improving conventional materials such as steel. [ 10 ]
Resultant concrete has shown up with least permeability for having developed pore refinement, containing nano pores. 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 ...
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.
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]
Concrete typically comprises sand, aggregate, water and cement and it is the cement part of the concrete that has the largest single CO 2 emission impact. Approximately 14 billion m 3 of concrete is poured globally each year, [ 7 ] this equates to more than 32 billion tonnes or 1,070 tonnes per second.
