obviously cement is a mix of limestone and silicon dioxide
I consider cement as a heterogeneous mixture.
Cement, sand, limestone, and sodium carbonate combined can form a type of mortar or cement mixture that can be used in construction. Sodium carbonate helps improve the workability of the mixture and can act as a stabilizer for the cement.
Cement is a mechanical mixture. It is composed of different materials such as limestone, clay, and gypsum that are physically mixed together but retain their individual properties.
This mixture would result in concrete. Cement is the binding agent that holds the mixture of sand, limestone (aggregates), and sodium carbonate together to form a solid and durable material used in construction.
Cement typically contains minerals like limestone, clay, silica, and gypsum. These minerals are essential for binding and hardening the mixture to form the final cement product.
Limestone is made up of calcium oxide which is the key ingredient to make cement. The limestone is mixed in with a particular clay to get the cement mixture.

Limestone, CaCO3 decomposes into quicklime, CaO, and carbon dioxide, CO2, when heated. The reaction is: CaCO3 + heat --> CaO + CO2.
Cement is formed from limestone through a process called calcination, where limestone (calcium carbonate) is heated at a high temperature to break it down into lime (calcium oxide) and carbon dioxide. The lime is then further processed and combined with other materials like clay to create cement.
Glass is primarily made from silica (silicon dioxide), along with other additives like soda ash and lime, which help improve its properties and lower its melting point. Concrete, on the other hand, is made by combining cement, which is made from limestone and clay, with aggregates like sand and gravel. Water is also added to the mixture to activate the cement and allow it to harden into a solid material.

Cement is a heterogeneous mixture because it is composed of different components, such as limestone, clay, and other materials, that are not uniformly distributed throughout the mixture.
To make cement with limestone, you need to heat a mixture of limestone and clay in a kiln to about 1400°C, which produces a chemical reaction called calcination. This process breaks down the limestone into calcium oxide (also known as quicklime) which is a key ingredient in cement production. The quicklime is then mixed with other materials such as sand and water to create the final cement product.
