Highlights
Lightweight concrete has been implemented in civil engineering construction for approximately 3,000 years, with the use of volcanic ash as a fine aggregate (Maruyama and Camarini 2015; Chandra and Berntsson 2003)
Visual inspection of the lightweight cellular concrete (LCC) samples revealed that the vesicular sections of cellular concrete were crushed under unconfined compression (UC) loads
In order to characterize LCC materials for use in earth-retaining structures, LCC samples having of four unit weights were tested using various shear-testing devices and conditions to measure shear strength parameters, coefficients of permeability, and at-rest earth pressure coefficients
Summary
Lightweight concrete has been implemented in civil engineering construction for approximately 3,000 years, with the use of volcanic ash as a fine aggregate (Maruyama and Camarini 2015; Chandra and Berntsson 2003). LCC provides a more economical alternative than traditional methods for reducing loads on different infrastructure (Maruyama and Camarini 2015; Tikalsky et al 2004; LaVallee 1999; Aberdeen Group 1963). UCS, total and effective shear strength parameters, consolidation characteristics, at-rest earth pressure (Ko) coefficients, hydraulic conductivity, and Poisson’s ratio values were measured for LCC samples prepared at four different test densities. Using this information, recommendations for design of the backfill of mechanically stabilized earth (MSE) walls using LCC are provided
