How to Reduce the Cost of Concrete Production. Two of the toughest challenges we hear for ready-mix producers are the lack of automation available and the cost and hassle of returned concrete. The problem: Rejected concrete loads are costly. Another occurrence is a project simply has leftover ready-mix concrete. .

The benefits of using steel fibres in concrete are as follows: 1. Steel Fibres are generally distributed throughout a given cross section whereas reinforcing bars or wires are placed only where required 2. Steel fibres are relatively short and closely spaced as compared with countinuous reinforcing bars of wires.

The bearing length should be atleast 75mm to avoid spalling of the edges. To prevent this short of failure occurring, the slab must be tied to the beam.
