w w w .ar fe n .c o m ARFEN SLAB JOINT MONTAJ AKSESUARLARI STEEL PLATE SOCKET In order to ensure long-term use of slab joints and high performance, the load transfer must be applied correctly and care should be taken to ensure that both sides of the joint remain at the same level. There are two ways to achieve this for vehicle traffic. Joints must be filled with suitable materials such as mastic and the corners should be reinforced with steel plates. Where concrete slabs are to be cut, the steel sheets on both sides of the joint must be used to protect the edges of the joint. These two...

There are two basic methods for controlling and preventing cracks on the concrete surface. The first method is to increase the amount of steel reinforcement that will prevent random crack formation. When cracks are controlled by steel...

SLAB JOINT SHRINKAGE - EXPANS IONJOI NTS The second and most commonly used method of preventing crack formation and random crack formation is to use Arfen slab joints in concrete slabs. In this method, weak lines are created at predetermined places in the upright, and the concrete is cracked in a straight line along this line. It allows to work without damaging the aesthetic appearance on the concrete surface which cracks down from the concrete surface along this joint. Slab concrete laying is still cracked as normal behavior, but random crack formation is prevented and an unbroken or...

In the case of airport constructions, if the concrete slab thickness is less than 30 cm, the joint interval can be accepted as long as it is between 9 meters and 12 meters and if it is more than 30 cm, the joint interval can be accepted as about 15 meters. (Design of concrete airport pavement -Page 26) Here, the coefficient of 9.9 x10-6 is the coefficient of elongation of one meter section of concrete...
