Basics of Geopolymers
The term ‘geopolymer’ was first introduced by Davidovits in 1978 to describe a family of mineral binders with chemical composition similar to zeolites but with an amorphous microstructure. Unlike ordinary Portland/pozzolanic cements, geopolymers do not form calcium- silicate-hydrates (CSHs) for matrix formation and strength, but utilise Read More
A dwelling built entirely according to the principles of Vastu is the most powerful method to build true bridges between the forces of nature and the residents.
Vastu is a complex, and at times, a seemingly esoteric science, but ultimately it always leads to stable objects in material form. These universal principles have been implemented in buildings on all contin Read More
Vertical farming is the practice of producing food and medicine in vertically stacked layers or vertically inclined surfaces .
The modern ideas of vertical farming use indoor farming techniques and controlled-environment agriculture (CEA) technology, where all environmental factors can be controlled. These facilities utilize a Read More
A differential couples the longitudinal input propeller shaft to the pinion, which in turn drives the transverse gear of the differential. This also works as reduction gearing. On rear wheel drive vehicles the differential may connect to half-shafts inside an axle housing, or drive shafts that connect to the rear driving wheels. Front wheel drive vehicles tend to have the engine crank Read More
A pillow block, also known as a plummer block or bearing housing, is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. Housing material for a pillow block is typically made of cast iron or cast steel. Read More
Slider-crank mechanism, arrangement of mechanical parts designed to convert straight-line motion to rotary motion, as in a reciprocating piston engine, or to convert rotary motion to straight-line motion, as in a reciprocating piston pump
Another mechanism that has a very wide usage in machine design is the slider-crank mechanism. It is mainly used to c Read More
At the forefront of worldwide skyscraper activity, Jeddah Tower represents an unprecedented exercise that dares to go beyond the one kilometer threshold, a height that seemed only to exist in fantasy just years ago. Inspired by a bundle of leaves shooting up from the ground, it is meant to emanate the growth, prosperity, and regional emergence of its homeland on the g Read More
