Abstract

Research on the Effect of Mixed Addition of Cement And rice husk ash Against and Stabilization on Roads Budi Utomo I aims to determine the effect of Addition of Cement And rice husk ash and to finding the optimal mix levels of Addition of Cement And rice husk for land Stabilization. Tests conducted at the Laboratory of Engineering, University of Bengkulu and the types of tests as follows: natural water content, specific gravity, sieve analysis, atterberg limits, standard proctor,and CBR (California Bearing Ratio) laboratories. Based on laboratory testing, native land in Jalan Budi Utomo I was clay with high plasticity After testing the original soil coupled with a mixture of cement and rice husk ash obtained optimum results occur at levels of 12 % of the 4%, 8%, dan 12% variations. The following test results with a mixture of cement and rice husk ash with levels 12 % : on the CBR laboratories testing provide CBR value increase up to 148.42 % of the original soil CBR by weight of the dry contents increased up to 3.846 % of the dry weight of the contents of the original soil. The optimum moisture content decreased to 13.754 % of the original soil optimum water content, whereas soil plasticity index dropped to 50.084 % of the original soil plasticity index, and the specific gravity value of the land increased to 1.923 % of theoriginal soil. Improved stability of the soil caused by cement and rice husk ash containing silica elements where this element has a very large contribution as an adhesive and can harden by reaction with water so as to increase the strength of the soil stabilization.

Abstract

CBR value research on soil stabilization with cement in the Budi Utomo UNIB Depan for influence soil properties and soil CBR original value after stabilisation with cement. Geotechnical Lab Testing was conducted at the Faculty of Engineering UNIB. Test laboratory soil properties include: density, water content, sieve analysis, Proctor standard test, Atterberg limits, and experimental value of CBR (California Bearing Ratio) laboratory. Stabilization soft soil made with cement with the addition of cement content of 0%, 2%, 4%, 8% and 12%. Based on test results propeties soil and the value of laboratory CBR. CBR maximum value at additioning cement content of 12%, the CBR value an increase of 144.21%, of the original soil conditions, dry density increase 3.85%, of the original soil, optimum moisture content decrease 13.75% of the original soil, PI value decresel 50.42% of the original soil, the value of  specific gravity (Gs) increse 1.93% of the original soil. Stabilization with cement increasing the value of CBR, which means it will also boost the stability of the soil and will also increase the soil bearing capacity (qu). The increase in soil stabilization and soil bearing capacity proportional to the increase in the value of CBR amounted to 144.21%, this is due to the presence of silica, clay and limestone contained in the hydraulic cement is a binder.
