Pengaruh Stabilisasi Tanah Pasir Candi Prambanan Menggunakan Tanah Butiran Halus dan Kapur

Abstract

Soil reinforcement carried out at Prambanan Temple was carried out to strengthen the slopes that would be used as rainwater runoff so that erosion did not occur. In this final project, reinforcement was carried out by mixing sandy soil and fine-grained soil with a percentage of the sandy soil of 90%, 80%, 70%, and 10%, 20%, and 30% of fine-grained soil, respectively, which will be tested using standard proctor testing. The percentage of the mixture that has the maximum dry density value (γd max) and the largest optimum moisture content (Wopt) is stabilized using extinguished lime as much as 1%, 2%, and 3% with a ripening age of 1 day, 3 days, and 7 days which will be tested for parameters. the shear strength using direct shear test and UU triaxial. The results of the study showed that the maximum dry density value (γd max) with variations in the mixture of sandy soil and fine grained soil 90% & 10%, 80% & 20%, and 70% and 10% respectively was 1.789 gr/cm3, 1.756 gr/cm3 , and 1,612 gr/cm3 and the optimum moisture content (Wopt) of 16.51%, 19.545%, and 21.985%, respectively, and the direct shear and triaxial test of UU obtained an increase in the value of the soil shear angle and cohesion with the addition of lime and along the length of curing time.
