A project I am reviewing has experienced cracking of the gypsum-containing grout poured in formed sockets in a PT concrete slab to secure aluminum guardrails. The cracks radiate from the rail to the edge of the formed socket. The grout material is also "soft" and can be chipped away with a screwdriver.
Does anyone have experience with an explanation of this failure and are there any publications/code sources which support the conclusions drawn.
