INTRALOK binding agent is a high solid aqueous emulsion auxiliary material suitable for modifying Portland cement formulations. It is also designed to be used as a bonding agent between new concrete and solid concrete It is a milky white liquid, not yellowish, ready for use and does not require dilution on-site.
Placeo Cemcol is a high strength concrete adhesive and the best option for situations where the top surface contains solid aggregate or will be subject to heavy traffic. It comes in powder form, which must be mixed with water on-site and applied to a plate moistened with water the day before. Imagine keeping the rebar in shape and pouring concrete and letting it harden and set. Now you have a rod built into the concrete. The total strength of the bond is the bond quality factor (weak/strong – depends on the quality and mixing of the concrete, and the condition of the reinforcing surface) multiplied by the length of the depression. Now try to remove the tape. This action will create pressure on the combined curved contact surface of the tape. Links Pressure! In designing reinforcement, this is one of the controls implemented. If the bonding voltage is within the permissible limits. Otherwise, we need to increase the area, but keep the same designed cross-section. This is achieved by reducing the diameter of the rods and increasing the number of rods.
The stress acting on the reinforcing interface and the concrete running parallel to the tape due to the bonding agent, mechanical sealing and friction forces between the concrete and the steel is called the bonding stress. Now it works as a transfer element so it helps in transferring axial loads from steel to concrete by developing transverse forces along the contact surface. The formwork is lubricated so that the concrete does not adhere to and adhesion stresses to the formwork (abutment, formwork, or formwork). Rust on steel bars affects bond stress. Having a little and long process of reinforcement has been found to develop more bond stresses than thick, regular sections. Bonding stress can be tested by pulling test.
The strength of the bond is the result of the bond between the concrete surface and the rebar. It varies according to the type of concrete and the type of reinforcement used Simply, it’s like a grip, more grip if the surface is rough and less grip if the surface is smooth and round.
