Sep 28, 2018· Concrete is a relatively easy material to, you can run into huge problems if it is not worked on properly. Concrete problems vary but could include discolorations, shrinkage, scaling, and various other problems.
The durability of the concrete is consequently improved except, perhaps, in freezethaw conditions, where excessive vibration can expel amounts of purposelyentrained air which is designed to increase the freezethaw resistance of hardened concrete. The abrasion resistance of concrete surfaces is normally improved by adequate compaction.
Slipform. Slipform is similar in nature and application to jumpform, but the formwork is raised vertically in a continuous process. It is a method of vertically extruding a reinforced concrete section and is suitable for construction of core walls in highrise structures – lift shafts, stair shafts, towers, etc.
