Pullout Strength Of Welded Wire And Ribbed Strip Reinforcement In Lightweight Cellular Concrete Backfill Behind Mechanically Stabilized Earth Wall, Mathew Robert Bueckers
Pullout Strength Of Welded Wire And Ribbed Strip Reinforcement In Lightweight Cellular Concrete Backfill Behind Mechanically Stabilized Earth Wall, Mathew Robert Bueckers
Theses and Dissertations
Lightweight cellular concrete (LCC) is a cement, water, and air entrained mixture that consists of 25-80% voids. The air voids reduce the material strength but also decrease the material weight. Due to its lightweight properties LCC is an attractive alternative to soil backfill for retained structures, such as mechanically stabilized earth (MSE) walls. Although LCC is widely used behind MSE walls, limited information exists regarding the pullout strength of MSE wall reinforcements in LCC backfill. This research attempts to fill the knowledge gap through performing pullout tests on welded wire and ribbed strip reinforcements in MSE walls to determine the …

Lcc Mse Walls, Joel Smith
Theses and Dissertations
Lightweight cellular concrete (LCC) is mainly a mixture of water, cement, and foam bubbles. LCC generally has a cast density between 20-60 pcf and an air content between 49-84%. LCC is often used as a fill material because it has a low unit weight which reduces settlement. LCC is increasingly being considered as a backfill behind Mechanically Stabilized Earth (MSE) walls and embankments. Although engineers are using LCC in MSE walls or free face walls (MSE wall without the concrete panels or reinforcements), there is presently a lack of information regarding the performance and behavior of LCC to guide them. …
Large-Scale Testing Of Lightweight Cellular Concrete Backfill For Sliver-Fill Mse Wall Configurations, Meghann Dee Morgan
Large-Scale Testing Of Lightweight Cellular Concrete Backfill For Sliver-Fill Mse Wall Configurations, Meghann Dee Morgan
Theses and Dissertations
Lightweight cellular concrete (LCC) is an aerated or foamed concrete where 25-80% of the concrete matrix consists of air voids. The high volume of air voids reduces the strength but significantly decreases the weight of the material, which has made it an attractive alternative to soil for retaining structure backfills. Though the use of LCC has increased, little research has been performed on the large-scale behavior of retaining structures containing LCC as backfill. This research test attempts to fill knowledge gaps found with regard to the use of LCC in a mechanically stabilized earth (MSE) wall with a trapezoidal or …
