説明

This paper presents the effects of various cement-rice husk ash proportions on the geotechnical properties of lateritic soils. Physical properties of both rice husk ash (RHA) and original lateritic soils were determined. The influences of different mix proportions of cement and RHA on Atterberg limits, compaction characteristics, unconfined compressive strength, California bearing ratio and swelling of lateritic soils were studied. Test results show that these lateritic soils stabilized with cement-RHA mixtures can be used in highway construction. From the point of view of compressive strength, California bearing ratio and economy ; this study recommends a mix proportion of 6% RHA+3% cement for sub-base materials and 6% RHA+6% cement for base materials.
