Expansion joints in concrete

When concrete is poured, it is very important to cut expansion joints in the concrete. By cutting control joints in the concrete you can better control the random cracking that inevitably occurs in concrete slabs soon after the concrete is poured and set. Concrete saw cutting can be a hard task, but cutting expansion joints can be harder still ...An isolation joint is a separation of an existing concrete slab from a new concrete slab or wall. A piece of expansion joint (usually ½” wide and made of cork or recycled fiber material) is placed against the existing concrete slab and when the new concrete slab is poured, this expansion joint separates the two slabs. The expansion joints are normally located between sections of bridges, paving slabs, railway tracks, and piping systems. Weather changes during the year produce temperature variations that cause expansion and contraction in concrete paving slabs, building faces, and pipelines. The expansion joints are incorporated to endure the stresses. I replaced old rotten wood expansion joints at concrete driveway and walkways. Typical 2x4 size. Cut to fit as needed.

However, if care is taken to allow non-autoclaved aerated concrete, spe- clally precast blocks to dry and thus contract before use, the shrinkage values may be considerably reduced and a value of 0% mm/m may be allowed.Joint Waterproofing. Due to the nature of concrete and reinforced concrete, structures are built divided into sections by forming joints, namely three types – construction joints, movement joints and connection joints. The key function of joint sealing is to minimize water ingress and create a secure waterproofing barrier.2. Expansion Joints. These joints are provided to allow for expansion of the concrete, due to rise in temperature above the temperature during construction. Expansion joints also permit the contraction of the element. Expansion joints in India are provided at an interval of 18 to 21 m.
