A reference specimen was defined as a one-sided fire exposed slab with the dimensions 1800 脳 1200 mm2 giving an exposed area of 1500 脳 1200 mm2. A number of concrete qualities with different probabilities for spalling, were tested using the reference specimen. These tests showed that the ...
The number one reason for indiscriminate cracking in slab on grade concrete is improper placement of control joints !!! I must emphasize again, how important proper placement of control joints in slab on grade concrete is to the prevention of indiscriminate cracks !!!

In this paper, the interface shear resistance of only the first type (CC–UHPC) is investigated experimentally and analytically, to assist designers in estimating the required interface shear reinforcement for applications where UHPC topping/slab is cast on CC beam/girder. Examples of these composite...
