The Effect of WHA and Lime for Shear Strength of Clay Stabilized by Cement

With the use of additive, clay's shear strength and bearing capacity increased. Usage waste material, Wooden Hush Ash (WHA), is tiny. The silicate content WHA almost same as RHA. This study aims to utilize ASK for a stabilization material high plasticity clay increase strength. Unconfined Compression Strength (UCS) tests were performed compare UCS value clay; with 5% cement; lime; clay-cement WHA; lime WHA. Before test, sample was separated into two groups: without curing 28 days, soaking 4 days. While in conditions unsoaked, qu uniform. Results show, soaked, values all variations have range 350 kPa 380 kPa. In days from 365 485 mixtures combination ASK. adding 10% additive increases 1100 testing results prove, more optimal than Replacement by 4% 6% 160 465 110 440 475 soaked unsoaked condition respectively. can be used reduce soil stabilization.
