This journal is designed to reflect current developments and advances being made in the general field of cement-concrete composites technology and in the production, use, and performance of cement-based construction materials.The word cement is interpreted in a wide sense, including not only Portland cement but also blended cements and other binding materials.
physics, chemistry and recent nanotechnology advances, the challenge was fulfilled.Lab tests and production tests proved that the nano silica did not contaminate (because its state), but it also produced better results than micro silica, and a litre bottle of the product was equivalent to a barrel full of micro silica, extra cement and super ...
Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

Posted: : Nanotechnology in the cement industry - a patent analysis (Nanowerk Spotlight) Cement is one of the most widely used materials in construction industry.In 2011, the expected total worldwide production of cement was 3,400 million tonnes.
While the meaning of “nanotechnology” varies from field to field and country to country and is widely used as a “catch all” description for anything very small, nanotechnology is commonly defined as the understanding, control, and restructuring of matter on the order of nanometers (i.e., less than 100 nm) to create materials with fundamentally new properties and functions .
nanotechnology patents in a manner resembling a gold rush. The nanotechnology gold rush has specifically targeted nanomaterials, nanotechnology’s building blocks. Many of the patents that have been granted for nanomaterials are broad, general patents encompassing basic research. A driving force behind the patenting
This book is aimed principally at university, college and polytechnic students who wish to understand concrete for the purpose of using it in professional practice. Because the book is written in English and because it uses both SI and the so-called old Imperial units of measurement, the book is of interest and value in many countries, probably world wide.

Advantages and Disadvantages of Concrete. Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials act as a binder. The most important binding materials are cement and lime. Inert materials used in concrete are termed as aggregates.
