Expansion joint's specification depends structure to structure. It depends upon its use rather the purpose it is for.
Material used for expansion joint is Neoprene sheet of 50mm thick. Basically material should porous & medium density.
Eg. While connecting two different super structure viz. column, we can keep the sheet between the reinforcement of two columns tieing the sheet with binding wire & r/f.

What is the construction joint in water retaining structure?
The reinforced concrete construction is the construction joint in water retaining structure.
How do expansion joints in a sidewalk keep the concrete from cracking?
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.
What is an expansion joint in construction?
An "expansion joint" is a joint left in between sections of the same material, like concrete or steel, that allows movement as the material heats up or cools down. Without it, concrete, for example, can expand and crack in hot temperature.
What has the author Arthur R Lord written?
Arthur R. Lord has written: 'A handbook of reinforced concrete building design in accordance with the 1928 Joint Standard Building Code' -- subject(s): Reinforced concrete construction
How many feet before an expansion joint is installed in concrete sidewalk?
10 feet.
Concerned about the gap between the concrete edge or trim of pool and the rest of the concrete flooring?
I assume the "gap" you refer to is the expansion joint between the coping and the concrete deck. The expansion joint is there to prevent damage from occurring in case of movement. There should be no reason for concern, unless you are replacing the deck.
What do you put between slabs after laying them?
in between existing concrete and the new concrete you need to place an expansion joint in between the two.
The difference between contraction joint and construction joint?
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.
How do you know what size of an expansion joint cover to use?
This will depent on the where we need & what kind of materinals, each material having different properties, comonly concrete every 18M there will be expanstion joint of 12mm and in railway tracks every 300M, 10mm expansion joint.
How joint prevent expansion and contraction?
The joint doesn't prevent expansion and contraction but it limits the damage caused by thermal stress. It allows room for the concrete ( or steel ) to expand and contract without creating the severe cracks that would form without them.
What are the steps involved in the process of concrete expansion joint replacement?
The steps involved in the process of concrete expansion joint replacement include: Assessing the condition of the existing joint to determine the extent of replacement needed. Removing the old joint material using appropriate tools such as a saw or chisel. Cleaning the joint area to ensure proper adhesion of the new material. Applying a bonding agent to promote adhesion between the existing concrete and the new joint material. Installing the new joint material, such as a preformed joint filler or sealant, according to manufacturer instructions. Ensuring the joint is properly sealed and finished to prevent water infiltration and maintain structural integrity.
What is the process for performing expansion joint replacement in a structure?
The process for performing expansion joint replacement in a structure involves the following steps: Assess the condition of the existing expansion joint to determine if replacement is necessary. Remove the old expansion joint by cutting or removing the existing material. Prepare the area by cleaning and smoothing the surfaces where the new expansion joint will be installed. Install the new expansion joint material, ensuring it is properly aligned and secured. Seal the edges of the new expansion joint to prevent water infiltration and ensure durability. Test the new expansion joint to ensure it functions properly and provides the necessary flexibility for the structure. It is important to follow manufacturer guidelines and consult with a professional to ensure the replacement is done correctly and effectively.
