The spacing adjacent to cracks or joints may be varied to take advantage of the weakened plane. Usually, holes 1-1/2 to 2-1/2 in. (40 to 65 mm) in diameter are used for cementitious grouts and holes 1/2 to 3/4 in. (13 to 19 mm) in diameter are used for polymer foam grouts.

1. Less concrete, i.e. reduced slab thickness. 2. Reduction or elimination of random cracks. 3. Substantial reduction in joints, i.e. increased spacing of joints. Post-tensioning is an active rather than passive form of reinforcing. In other words, post-tensioning pre
Topping Slab Strength and Specifiions. For bonded and unbonded concrete topping slab, strength of concrete for concrete topping slab is governed by function of the slab; 30MPa for light duty, 40 MPa for medium duty, and 50 MPa for heavy duty. The concrete topping used should have a …
Order a 40N20 mix. This will ensure that the concrete will have a minimum crushing strength of 40N/mm2(newtons/mm2) and the biggest stone chips will be no bigger than 20mm. Specify also a minimum cement content of 350kg/m3and a slump not exceeding 100mm. The slump gives an indiion of the amount of added water.
Concrete pouring is a crucial process which not only needs properly qualified persons but also considerable focus and concentrations. Almost all codes have established certain specifiions to ensure proper concrete pouring and prevent its segregation. In this article, correct concrete pouring according to ACI 304R-00 is presented.
