soil cement mix design

Soil Cement Stabilization Mix Design, Control and

Soil-cement mixes were prepared with varying cement contents ranging from 4% to 6% by weight. The mix design requirement was to establish the cement content necessary to have a minimum unconfined compressive strength of 250 psi (1724 kpa) at 7 days. This paper presents the soil-cement mix design, field-laboratory procedure and results.
