Serafini, F.L. Corrosion protection of concrete using a Controlled Permeability Formwork (CPF) system; Proceedings of the International conference Corrosion and Corrosion Protection of Steel in Concrete (Ed R. Narayan Swamy), Sheffield, Vol. 2, 24–28 July 1994, pp. 1114–1131.
The SDR was originally defined in the Air Force's MIL-STD-1521. [1] The SDR is a technical review conducted to evaluate the manner in which a project's system requirements have been allocated to configuration items, manufacturing considerations, next phase planning, production plans, and the engineering process that produced the allocation ...
The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
A movable scaffolding system (MSS) is a special-purpose self-launching form used in bridge construction, specifically prestressed concrete bridges with segments or spans that are cast in place. The movable scaffolding system is used to support a form while the concrete is cured; once the segment is complete, the scaffold and forms are moved to ...
Climbing formwork, also known as jumpform, is a special type formwork for vertical concrete structures that rises with the building process. While relatively complicated and costly, it can be an effective solution for buildings that are either very repetitive in form (such as towers or skyscrapers) or that require a seamless wall structure ...
Concrete work is efficient and controlled as CCS functions as ready-made forms; CCS with concrete forms a flexible slab that accommodates minor subgrade movement and prevents cracking. In medium and low flow-velocities, CCS with geomembranes and gravel cover can be used to create impermeable channels, thereby eliminating the need for concrete.
An Azerbaijani airliner carrying 67 people crashed near the city of Aktau in Kazakhstan on Wednesday, killing at least 38 who were on board, according to a Kazakh official.
