Are fly ash and silica fume cementitious materials?
yes
Is silica fume dangerous to human health?
Silica fume, also known as microsilica, is a byproduct of the combustion of quartz, coal and wood chips during the production of silicon metals. silica improves compressive strength, bond strength, and the abrasion resistance of concrete. Prior to the 1970s, its release into the atmosphere was permitted, but environmental concerns eventually forced its collection and deposition into landfills. It then became economical for silica fume to be used in various applications, chiefly in high-performance concrete. Consisting of fine silicon dioxide particles that are approximately one-hundredth the size of the average cement particle, silica fume is the cement substitute of choice where high strength is critical, such as in high-rise buildings. Cement that contains silica fume looks darker than ordinary cement. Although a respirator should be worn while handling pure silica fume, a cement-silica fume mix is not considered dangerous to humans.

Is petrol a gas or a solid?
The word "fume" generally implies a gas. The only common exception I know of is in the two word phrase "silica fume", which is sometimes used for very fine solid silica particles that have been prepared by a process including a step of passing silica through a fume stage. Such solid material is preferably called "fumed silica".

How silica fume helps in increasing properties of concrete?
Silica Fume(Microsilica),They used in concrete. It can improve concrete's properties such as compressive strength, bond strength, and abrasion resistance; reduces permeability; and therefore helps in protecting reinforcing steel from corrosion. At the same time, ,silica fume can still be used in the production of refractory and porcelain; to raise intensity and durability, it also can be used in paint, coating, resin, rubber and other high molecular as a filler material to improve the material overall performance.
Do you put distilled water in a gel battery?
No,, distilled water is not used in a gel battery. The sulfuric acid is mixed with silica fume rather than distilled water. This is what makes the gel.
