A cast-in-place reinforced concrete structure is safer and stronger than any other commercial building types. According to researchers at the National Institute of Standards and Technology, steel, when exposed to fire, loses its strength and stiffness much faster than high-strength concrete. High-strength concrete, which has a lower thermal conductivity, will maintain its structural integrity for a longer period of time in a fire situation.
As a result of the Christchurch earthquakes, many Engineers are looking at placed in-situ as the preferred construction method. Shotcrete as repair technology can also be used to construct a building initially.
Since requests for changes are not uncommon during a construction project, the design flexibility of cast-in-place reinforced concrete permits the contractor to accommodate design changes after the process has begun.
A Cost-Effective Solution
Cast-in-place reinforced concrete provides benefits both during and after construction. In addition to being safer and faster to build, it is also more cost effective and allows flexibility of design in construction.
Commercial alternative to Tilt-slab
Shotcrete as a placed “in-situ” concrete system, has no weak points, just one continuous steel reinforced wall.
