Early Entry Concrete Saw
Early Entry Concrete Saw
(OP)
ACI 360 recommends sawcutting to 1/3 of the slab depth for control joints in steel fibre reinforced slab on grade.
Does anyone know of an ACI or PCA publication that gives a recommendation for depth of sawcut in steel fibre reinforced slab on grade if an early entry saw is used?

Unrelated to sawcut depth, but the main advantage of steel fibres is not that they increase the modulus of rupture much (at the normal doaseges) but rather that they provide the slab with signifcant post-cracking strength. If this is accounted for, there can be a dramatic reduction in required slab depth, if the yield line analysis takes proper account of the post-cracking strength.
