Abstract
Abstract
Surface layer of earth’s crust in Kingdom of Saudi Arabia is composed of loose sand with soluble salts, which is generally termed as Sabkha. Poor strength and durability characteristics of the Sabkha soil adversely challenge the safety and serviceability of infrastructure built on it. Therefore, improvement of its physical properties demands urgent attention of the engineering society. In this study, date palm ash (DPA), a local industrial waste, is utilized as an additive to improve strength characteristics of problematic Sabkha soil. A remarkable improvement in compaction characteristics and compressive strength is achieved. By investigating the effect of different proportions, the optimum quantity of additive is determined with respect to compressive strength.
