Micro structure of concrete with nano materials gets changed like anything and is resulting tremendous increase in compressive strength apart from increase in specific surface area.
the main difference is we will not at all use the ordinary port land cement in the geo polymer concrete mix simply we will use fly ash as a binder material and a chemicals such as sodium silicate and sodium hydroxide are used
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.

Polymer concrete is a composite material which results from polymerization of a monomer/aggregate mixture. The resulting polymer binds the aggregate making the concrete stronger than ordinary concrete using just standard aggregate.

When you think about designing an outdoor patio area, concrete may be one of the last materials you consider. After all, you're dying to do something out of the ordinary in order to get rid of that dull gray look. Concrete decks and patios provide unique opportunities to explore some of the latest innovations in concrete finishing, whether you choose to use an interesting stamp design, a beautiful color of stain, or an interesting material as an inlay.
yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
yes
Under normal conditions of pH and oxygen concentration, passivation is seen in such materials as aluminium, iron, zinc, magnesium, copper, stainless steel, titanium, and silicon. Ordinary steel can form a passivating layer in alkali environments, as rebar does in concrete. The conditions necessary for passivation are recorded in Pourbaix diagrams. The Passivation process is typically an immersion process involving nitric acid. Passivation is the process of making a material "passive" in relation to another material prior to using the materials together
Ordinary Portland cement is the most common cement used in the world, made from stucco, concrete, mortar and other materials. Slag cement is usually mixed with Portland cement and is the substance leftover after metal has been smelted from raw ore.
The raw materials needed to make ordinary portland cement are,Calcium oxidesilicon dioxideAluminium oxideIron oxideMagnesium oxideAlkaliessulphurtrioxide.

Class A extinguishers are designed for "ordinary flammable materials" (organic solids such as paper and wood) but not liquids like gasoline, grease, electrical fires, or flammable metals.
Ordinary structural concrete is characterized by its water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete
