The silica-to-alumina ratio determines the strength and setting time of cement.
• Good quality cement requires a silica to alumina ratio between 2.5 and 4.1.
• Aratio of 3 ensures optimal strength and durability, making it suitable for construction
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
