🏗️Структура и марки

Бетон · Гидравлическая керамика городов: цемент, вода, заполнитель и обычно сталь.

What holds Бетон together is not the nickname. Formula C-S-H binder + aggregate, density ~2400 kg/m³.

Meters are atlas-relative. Grades are the SKUs buyers write.

Фазы

C-S-H binder + aggregate

Chemistry

Бетон is specified as C-S-H binder + aggregate. Density band ~2400 kg/m³.

Microstructure

Order

Processing sets grain, crystallinity or fibre orientation — the reason two lots of Бетон can test differently.

Interfaces

Surfaces

Coatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.

Defects

Flaws

Inclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.

Grades

Variants

Бетон is a family. Grade names below are the ones buyers actually write on RFQs.

Ageing

Time

Moisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.

Primary bonding

Бетон holds together by ionic/covalent networks.

Secondary forces

Hydrogen bonds, van der Waals stacks or grain-boundary cohesion set toughness and moisture uptake.

Composites & fills

Fillers, fibres, plasticisers or aggregates are part of the real product, not impurities.

Environment film

Oxides, chars, sizings or paints are the layer the world actually meets.

Change the grade, the coating or the moisture and you have a different material with the same English name.
