Pullout Resistance of Reinforcement in Lightweight Cellular Concrete Fill

项目名称：	Pullout Resistance of Reinforcement in Lightweight Cellular Concrete Fill
摘要：	Backfill materials have been commonly used as reinforced fill in Mechanically-Stabilized Earth (MSE) structures. Natural aggregate (gravel or sand) and crushed stones are the primary materials used as backfill for this application. However, aggregate is relatively heavy, so it often induces high earth pressure, settlement, lateral movement, and instability of earth structures. To avoid these problems, lightweight aggregate has occasionally been used. Due to the limited availability and high cost of lightweight aggregate, lightweight cellular concrete fill has grown in popularity in recent years, e.g., used as a backfill material for MSE walls. However, there is very limited information on pullout resistance of reinforcement (e.g., steel strips or geogrids) in lightweight cellular concrete fill at different conditions (reinforcement type, curing time, and normal stress), which is required for design of MSE structures. The objective of this research is to evaluate the pullout resistance of reinforcement in lightweight cellular concrete under different conditions.
