GB/T 16753-2023Terms for silicate building products (English PDF)

3.1

It mainly uses siliceous materials and calcareous materials as raw materials. After batching and molding, a hydrothermal synthesis reaction occurs in an autoclaved (or steam-cured) environment to produce

Hydration products such as calcium silicate hydrate and calcium aluminate hydrate are the main cementing materials and are used in finished products in buildings or structures.

3.2

Under certain temperature and pressure conditions, calcium materials, siliceous materials and water react chemically to form hydrated calcium silicate, hydrated calcium aluminate, etc.

A process with hydraulically gelling chemicals.

3.3 calcareousmaterials

In the production of silicate building products, it refers specifically to raw materials that can provide the required calcium components for its hydrothermal synthesis reaction.

Note. Usually in the form of calcium oxide (CaO) or calcium hydroxide [Ca(OH)2].

3.4 silicone materialssiliceousmaterials

In the production of silicate building products, it specifically refers to raw materials that can provide siliceous components for its hydrothermal synthesis reaction.

Note. Usually found in the form of quartz and silica glass bodies.

3.5 Autoclaved lime sand silicate

Use sand as the main siliceous material, quicklime or carbide slag as the main calcareous material, add an appropriate amount of gypsum, admixtures and other aggregates, and pass through the blank

Preparation, pre-curing and high-pressure steam curing of silicate building products.

3.6

Fly ash is used as the main siliceous material, quicklime or calcium carbide slag is used as the main calcareous material, and an appropriate amount of gypsum, admixtures and other aggregates can be added.
