Concrete Partitions

Concrete partitions consist of concrete slabs, plain or reinforced, supported laterally between vertical members. These slabs may either precast or cast-in-site.

• Cast-in-situ concrete partitions are usually 80 to 100mm thick, cast monolithically with the intermediate columns. Such partitions are rigid and stable along both vertical and horizontal directions. However such partitions require costlier form work.
• Pre-cast slab units are commonly used for partitions. These slabs may be quite thin (25mm to 40mm) and are secured to precast posts. Concrete mix usually adopted is M 15(1:2:4). The joints are filled with cement mortar.
• Another form of concrete partition is made from pre-cast T-shaped or L-shaped units. A light weight, hallow partition is obtained without any necessity of vertical post. Cement mortar (1:3) is used for jointing.
