Elastic Concrete Joint
Elastic concrete joints are formed with polyurethane materials of two ingredients
and special aggregate.
These joints can be used immediately just through mixing the main material, hardener
and aggregate at the construction site, and they have a waterproof function with
adhesion with regard to strong concrete.
In addition, elastic concrete is used as fillers of expansion joints to absorb impulsive loads of vehicles, and equally conveys and distributes loads to lower structures.
Elastic concrete which is highly ozone-resistant, chemical-resistant and abrasion-resistant
is a material which is easy to work with.
Features | -During the rainy season, elastic concrete can induce drainage of water penetrating into the pavement layer, minimizing concrete damage. -The elastic material which possesses elasticity and semi-rigidity is highly durable. -Elastic concrete has excellent adhesive power with the existing pavement layer and concrete. -There is almost no plastic deformation. -Trafficability is good because continuity with the existing pavement layer is maintained. -Workability is excellent even with steep end gradients. -The elastic material is cured quickly, and traffic is opened fast. (within 2 hours) -When the material is used, construction becomes simple, and maintenance and repair become easy. |
Uses | - Underground road joints - For repairing concrete of highways, etc. - For repairing concrete of harbors and waterfront - Post-placing concrete for the block-out part of expansion joints - For filling space - Other parts that need waterproofing or absorb shock |
Preparation | Elastic concrete shall be applied for parts from which pollutants, such as dust and oil are removed. The ordinary Portland cement concrete shall be generally applied after being cured for over 14 days. The planes and the side faces for installation shall be chipped and grinded to become straight. After sand blasting, pollutants shall be removed cleanly before construction. |
