· If you calculate the weight of your steel for a given concrete volume, you can then calculate "w" as follows: w = Ws/(ws*V)*(ws-wc)+wc [EQUATION 2] Where Ws = Total weight of reinforcement for a given total volume V. You''d then have a handy-dandy value for "w" (again, in frostryan''s example w = 165 lb/ft3) to plug into EQUATION 1, to estimate ...
For slabs = 1.0 % of concrete volume. For Beam = 2 % concrete volume. For column = 2.5 % of concrete volume. For RCC Roads, 0.6% concrete volume. Lets take example of RCC Column, where reinforcement required is 2.5% of concrete volume, weight of steel required will be: =196.25 kg.

The concrete was sprayed on in layers of approximately 3–5 mm, alternating with the textile reinforcement. Thus a strengthening layer of only 15 mm in thickness was created and, using TRC in contrast to steel-reinforced concrete, the additional weight could be reduced by over 80%. Before construction started, the adhesive bonding and the ...
