Minimum rebar spacing

The distance minimum rebar spacing reinforcement bars must be such to allow the largest expected concrete size gravel to pass between them. In order to have properly anchored reinforcement, it is mandatory for rebars to be surrounded by concrete, minimum rebar spacing. The minimum spacing between two reinforcement bars should be at least equal to the maximum coarse aggregate dimension plus a margin of 5 mm. For Greece, the maximum aggregate grains dimension for usual concrete, is 32 mm and for self-compacting concrete is 16 mm.

ACI American Concrete Institute has developed guidelines to help in design of reinforced concrete beams. Some of them are given below. Spacing of Reinforcement. Minimum clear spacing between parallel bars in a layer should be equal to diameter of the bar but not less than 1 inch. Where parallel reinforcement is placed in two or more layers, bars in the upper layers shall be place directly above the bars in the bottom layers with clear spacing between the layers not leass than 1 in. Maximum spacing of reinforcement bars closest to the tension face shall not exceed the following;.

Minimum rebar spacing

In order to have properly anchored reinforcement, it is mandatory for rebars to be surrounded by concrete. The minimum spacing between two reinforcement bars should be at least equal to the maximum aggregate grain dimension with a margin of 5 mm. For Greece, the maximum aggregate grains dimension for usual concrete, is 32 mm and for self compacting concrete is 16 mm. These spacing requirements are easily met in slabs and columns. However in beams extra at-tention must be paid mainly to the support and the joint areas. For satisfactory results it is very important not only to use the vibrator in the proper way but also to avoid over-vibrating the concrete of the elements. Concrete casting in foundation connecting beams is not an easy procedure. Because of the fact that connecting beams normally have a large height as well as a large internal lever, it is preferable to place rebars in two or even three layers along their height. Large beam width b Use of the second layer, which is placed in contact with the stirrups. Connecting beams in foundation Concrete casting in foundation connecting beams is not an easy procedure.

The table given below is showing minimum beam width required for a reinforced concrete rectangular section as per ACI guidelines. Large beam width b Use of the second layer, minimum rebar spacing, which is placed in contact with the stirrups. The diameter of different bar sizes are given in brackets; 3 0.

The table given below is showing minimum beam width required for a reinforced concrete rectangular section as per ACI guidelines. This table is based on the assumption that maximum aggregate size does not exceed three-fourth of the clear space between bars, and the 3 bars are used as stirrup.
