Soil cement which is a mixture of soil, cement, and water has a broad range of applications since it is economical, ecological, and easy to use, repair, and reinforce. Its applications include pavements, stabilization of slopes, retaining walls, and improvements of soft ground to name a few. Other types of chemicals are often added to increase its strength. This study investigated unconfined compressive strength of cured soil cement mixed with New Soil Chemical(NSC). The investigation involved laboratory experiments under various conditions including soil type, cement content, and ratios of water to NSC. Results of the study show that NSC enhanced the unconfined compressive strength significantly, and the degree of enhancement was varied with test conditions.
