Effect of Engineering Properties on Resilient Modulus of Cohesive Soil as Subgrade

Journal of the Korean Geotechnical Society, 2013
The objective of this study was to identify the effect of engineering properties on the resilient modulus () of cohesive soils as subgrade. Eight representative cohesive soils representing A-6, and A-7-6 soil types collected from road construction sites, were tested in the laboratory to determine their basic engineering properties. The laboratory tests

Mix Proportion of Fly Ash Concrete Based on the Strength Contribution Ratio

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT This study aims to expand the use of fly ash concrete (FAC). Based on an experimental investigation of k values or the contribution of FA addition to the strength of ordinary Portland cement or Portland blast‐furnace slag cement type B, we propose and validate an environmentally friendly mix design for FAC.
