Abstract:
Mortar and plain concrete beams were subjected to mechanical load cycles in bending and various types of thermal cycles in the range 20 C to 400 C. From measurements of longitudial length changes, beam deflections, and load holding capacity of the beams, comparisions are made between mortar and concrete for thermal expansion, modulus of elasticity, creep deflections, and ultimate load for three types of thermal cycles.
