What grade of concrete use in column and slab?
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
What is the minimum anchorage length on re-bars in concrete cantilever beams?
you can generally use 180 degree hooks, to provide enough anchorage in slabs with no edge beams. use the Ldh formula (12.5.2) of ACI 318-11
What is the design life of concrete?
It can depend on the governing agency standards mostly, but the typical design life used by ACI (American Concrete Institute) is an average of 75 years. The normal range given in between 50-100 years.
What is a Class A splice in concrete reinforcing?
A class A splice is defined in ACI 318 Section 12.15. There are two types of splice (A and B) which define the length of the splice as a multiple of the tensile development length (ld) Class A denotes a splice that has 1.0 x ld of overlap. A class B splice has 1.3 x ld. Class B is required except where splices are kept out of critical ares (see the code).
For rebar that is embedded in a poured slab or in a sprayed concrete wall when is welding required and when will using twisted wire suffice Can you include a link to the standard Thnx.?
Tie wire should be used always, not welding. Rebar integrety is comprimised when welded. A specific grade of rebar, A706, exists for welding but otherwise, its is not advised that rebar be welded. See below:Q: When is it appropriate to use welded splices in the field? A: The ACI 318 Building Code requires the architect/engineer to indicate the type and location of welded splices of reinforcing bars on the project drawings or in the project specifications. The ACI 318 Building Code further requires that all welded splices should conform to the Structural Welding Code for Reinforcing Steel published by the American Welding Society, which requires the project contractor to prepare written welding procedure specifications (WPS) for all welded splices. These will depend heavily on the assessment of carbon-equivalent (CE) and other rebar properties as determined by the mill test reports that accompany each shipment. For more information about welding reinforcing steel, see the American Welding Society's (AWS)Structural Welding Code for Reinforcing Steel.Q: Can tack welding be used to hold reinforcing bars during assembly? A: Field tack welding should never be used as a substitute for tying in assembling and securing reinforcing bars. Rare exceptions are specified in the International Building Code.Source link: http://www.crsi.org/contractors/faqs.html

Why does the ACI code specify that a certain minimum percentage of reinforcing be used in beams?
to prevent the beam from failing immediately when a crack occurs. If the ultimate resisting moment is less than the crcking moment the beam wold fail, but by putting a minimum percentage of steel i the concrete this can be avoided.
