When milled waste glass is used in recycled aggregate concrete as partial replacement of cement, it interacts with calcium hydroxide available in the attached mortar/paste clinging to aggregate surface to form calcium silicate hydrate (C–S–H) which is the key binder among cement hydrates.
Concrete: Synthetic rock made using cement (usually, but not necessarily, Portland cement) mixed with aggregate and water. Mortar: Mixture of cement and fine aggregate, mainly sand. Used typically to bond bricks and building stone. Grout: Mixture of cement (possibly of various types) and other fine material such as fine sand. Used in a wide range of applications from filling the gaps between bathroom tiles to .

Aerated concrete is made from the raw materials silica sand, lime, cement, gypsum (anhydrite), aluminium powder/paste, and water. The precisely measured raw sand and the required quantity of water are fed into the wet ball mill where the raw sand is processed into sand slurry.

Aerated concrete is a lightweight, cellular material consisting of cement and/or lime and sand or other silicious material. It is made by either a physical or a chemical process during which either air or gas is introduced into a slurry, which generally contains no coarse material.
Finally mix sand with clay. During the process, spray some water. You will see that it's enough when your mixture is able to maintain a form. That's all. This green sand formula is working. It is possible to use this molding sand again and again.
Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materials:

In order to evaluate the risk of the source and quantity of cement SO3 on the expansion properties of mortars, this paper studied the influence of Gypsum, Bassanite and clinker sulfate on the cement paste expansion and the formation of delayed ettringite. The investigation covers the mortar cured at 20 °C and 80 °C and stored in water.
Cement Stabilized Sand. At Southern Crushed Concrete, our cement stabilized sand contains only lightweight pieces and is free of any organic damaging substance, as required by the City of Houston and Harris County. At Southern Crushed Concrete, our recycled materials are .
Hydration products. In a concrete made from cement containing only clinker and gypsum, ettringite forms early after the cement and water are mixed, but it is gradually replaced by monosulfate. This is because the ratio of available alumina to sulfate increases with .
