The extended-phrase sturdiness of Roman concrete structures was located being because of the presence of pyroclastic (volcanic) rock and ash during the concrete blend. The crystallization of strätlingite (a posh calcium aluminosilicate hydrate)[26] throughout the development on the concrete and its merging with related calcium–aluminium-silicate–hydrate structures helped provide the Roman concrete a bigger degree of fracture resistance as compared to modern concrete.
Superplasticizers (also called high-assortment drinking water-reducers) are a category of plasticizers that have fewer deleterious outcomes and can บริษัทเอสเอชซี สหะชัยคอนกรีต จำกัด be used to increase workability in excess of is sensible with classic plasticizers.
A further well-known result for flooring and table tops is polished concrete where by the concrete is polished optically flat with diamond abrasives and sealed with polymers or other sealants.
