Classification of steel mould concrete for box block
1. Classification by cementitious material
(1) Cement concrete. Portland cement, ordinary cement and fly ash cement are used as cementitious materials. This is the most widely used concrete in concrete engineering.
(2) Asphalt concrete. Natural or artificial asphalt is used as cementitious material. It is widely used in pavement.
(3) Gypsum concrete. Natural gypsum and industrial waste gypsum are used as cementitious materials. It is generally used for small blocks, plates and other internal partition products.
Construction technology classification of ladder slope protection mould and box block steel mould
(1) Ready mixed stepped slope protection concrete. After centralized mixing in the mixing plant, the concrete of the construction unit is supplied in the form of commodity, so it also becomes commercial concrete.
(2) Pumping concrete for step revetment. Concrete delivered and placed by concrete pump. At present, it is widely used in concrete structure construction, especially in high-rise building structure and mass concrete structure construction.
(3) Shotcrete box block concrete. High pressure compressed air is used to spray concrete through pouring pipe. It is mainly used for foundation pit support and tunnel lining engineering.
