Behavior of Reinforced and Unreinforced Lightweight Cellular Concrete for Retaining Walls

The overall objective of this study is to measure engineering design parameters and failure mechanisms for unreinforced and reinforced lightweight cellular concrete (LCC) backfills based on large-scale laboratory tests. Specific objectives are: (1) Determine and characterize the nature of strength criteria based on failure in large-scale laboratory tests. (2) Determine the failure mechanism for unreinforced LCC backfill behind conventional reinforced concrete walls along with wall pressures and deflections. (3) Determine the failure mechanism for mechanically stabilized earth (MSE) walls with LCC backfill along with wall pressures, required inextensible (steel) reinforcement length, and wall displacements. (4) Measure pull-out resistance of inextensible reinforcements at large-scale and under variable applied vertical pressures.
