What size rebar do I need for a concrete slab?
There are three different sizes of rebar which are needed for home projects are usually #3, #4, and #5. The rebar size #3 is used for driveways and patios. For walls and columns, #4 rebar size should be used as they require more strength. It is better to use the #5 rebar size for footers and foundations.
How much does 10mm rebar weigh?
Metric Mass/ weight of 10M rebar:- given size/ nominal diameter of 10M rebar is 11.3mm, using the formula d^2/162, to find out metric mass/ weight of 10M rebar per unit lenth, mass = (11.3 × 11.3)/162= 0.788kg/m, converting this weight into pound per foot per unit length, which is equal to 0.529lb/ft, converting this
Why is rebar called rebar?
Rebar, short for “reinforcing bar” or “reinforcement bar”, is a metal bar that is used to help increase the tensile strength of concrete.
