Based on the chemical composition, it was possible to differentiate between CaO-rich, basic brick types such as thermal insulating bricks and masonry bricks from current production and SiO 2-rich, acidic brick types such as clinker bricks.The reactivities determined with a modified Chapelle test were in a range between 97 mg/g and 328 mg/g.
Cement and water form a paste that coats each particle of stone and sand—the aggregates.Through a chemical reaction called hydration, the cement paste hardens and gains strength.The quality of the paste determines the character of the concrete.The strength of the paste, in turn, depends on the ratio of water to cement.
Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together.Cement used in construction is characterized as hydraulic or non-hydraulic.

The main component of cement is clinker, which is produced from raw materials, such as limestone and clay.Limestone supplies CaCO 3 for the cement production.Silica, alumina, and iron are considered to be other raw materials.
The production of Portland clinker, which acts as the binder, is a crucial step in making Portland cement.Limestone (CaCO3) is “calcinated” at high temperatures in a cement kiln to produce lime (CaO), leading to the release of waste CO2.
The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3).These are quarried and stored separately.
Two thirds or 5% of global emissions result from the chemical reactions in the cement production process and therefore cannot be eliminated through gains in energy efficiency.
