Effect of Cement Stabilized Kaolin Subgrade on Strength ...

Effect of Cement Stabilized Kaolin Subgrade on Strength Properties. Subgrade performance generally depends on the load bearing capacity of soil. This load is often affected by degree of compaction, moisture content and soil type. Poor subgrade should be avoided by removal, replace and add stabilizer agent to provide a suitable strength for ...

Effect of Calcined Kaolin on the Mechanical Properties of ...

Locally available kaolin has been calcined and used as cement replacing material (CRM) in High-strength concrete (HSC). Total five (05) mixes of concrete have been examined using calcined kaolin (CK) of 0, 5, 10, 15 and 20% by weight of cement. For each mix, compressive strength, splitting tensile strength and flexural strength have been determined by preparing three specimens.
