The difference between contraction joint and construction joint?
Wiki User
∙ 11y ago
A construction joint in concrete jobs is a joint where a fully set and hard concrete joins a fresh concrete to make a joint. Normally, cracks would occur at this joint because concrete was not cast monolithic. A contraction joint is joint between two concrete edges so formed which allows minute movement between the two edges caused by heat or some other external forces. Usually, contraction joints are also referred to as expansion joints.

What is the construction joint in water retaining structure?
The reinforced concrete construction is the construction joint in water retaining structure.
What is contraction joint?
A contraction joint is a sawed, formed, or tooled groove in a concrete slab that creates a weakened vertical plane. It regulates the location of the cracking caused by dimensional changes in the slab.
What is the difference between Expansion and construction joint?
A construction joint is required to allow the structure to be built. Say there is an existing structure in the way of a wall. Part of the wall is built, then later the existing bit is removed, and the rest of the wall constructed. The place where the first and second parts of the wall meet is a construction joint. This kind of joint is usually built so that no movement is allowed. An expansion joint is one that allows movement between the two elements. There will be a comparitely soft material, such as rubber, asphalt or impregnated board placed between the parts. The latest innovation has lead to use non bituminous filler boards like polymer based HD100 board. It is also known as micro cellular filler boards. (More details about filler boards you have to visit hd100.in or kampun.com from there in-depth product knowledge available.) If it is concrete construction, any reinforcing bars will be arranged to allow movement. In most cases, if movement was prevented, the structure would crack or buckle. The joint allows controlled movement.
What is the approved location of the construction joints in the raft foundation?
The best location to set the construction joint is less shear force impact. e.g:In slabs;it is better to locate between the supports.
What is the difference between pin joint and hinged joint?
in pin joint the linkages are free to move relative to one another angularly, whereas in hinge joint, one linkage is fixed and the other is free to move in angular direction.
Why do you use a construction joint?
Construction joints are very useful, the expansion & contraction made is made in summer & winter season respectiely. In summer coz of temprature concrete get expansion in mm but it damage the structure, that's why construction joint is provided. Sunil Nagargoje TESPL

What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.
