NANO CONCRETE - TECHNOLOGY AT ITS BEST

NANO-CONCRETE TECHNOLGY  Nanotechnology in the civil field has proved to make the construction faster, cheaper, safer and more varied. Automation of Nanotechnology construction can allow for the creation of structures from advanced home to skyscrapers much more quickly and efficiently.  Amorphous nano-silica (nS) particles were incorporated in cement concrete, and their effect on the fresh state behaviour was analyzed. Nano concrete is defined as concrete made by filling the pores in traditional concrete using nanoparticles of size <500nano meters .  Nanoparticles of silica turn into nanoparticles of cement (nano cement) in the chemical reactions that take place in the concoction of the concrete. When concrete is reduced to Nano level its properties are strongly influenced so that it increases their strength & durability.  Addition of nano-silica to the concrete leads to improve

Cement Composition & its Functions, Bogue's Compounds I Building Material I Civil Engineering

                                            CEMENT Introduction Cement is an extremely fine grounded material having adhesive and cohesive properties which provide a binding medium for the discrete ingredients. The processes used for the manufacture of cement can be classified as dry and wet. In the wet process , the limestone brought from the quarries is first crushed to smaller fragments. Then, it is taken to a ball or tube mill where it is mixed with clay or shale as the case may be and ground to a fine consistency of slurry with the addition of water. The slurry is stored in tanks under constant agitation and fed into huge firebrick lined rotary kilns. In the dry process , the raw materials are ground, mixed and fed to the rotary kiln in the dry state. Chemical Composition The identification of the major complex compounds is largely based on R.H. Bogue's work and hence these are called Bogue's compounds .   Functions of
