What is the standard size of concrete cube taken for compressive strength test?
It depends on the intended use, ranging from 25N/mm2 for concrete in a dry internal environment say an office floor slab. Up to 50N/mm2 for a large reinforced concrete arch dam.
What are the advantages of using a steel tube rather than a solid section?
good strength for weight, less material used, multi-function (liquids can be circulated through pipe-this was done to assist the curing of the concrete in the Hoover Dam by controlling the terrific heat generated within such a huge mass of concrete. the pipe then became additional reinforcing in the dam. ) easier to weld, can be internally wired
