Soils viable for engineering works needs to attain certain strength properties in order to serve its intended purpose. Some available soil like Black Cotton Soil tends to show weakness in strength which necessitate it to be modified so that the desired strength can be achieved, this can be executed using materials that could improve the soil properties such as gypsum, lime, bagasse ash, cement, etc. This paper is a review of the viability of the use of gypsum in proportion to other stabilization material to improve the strength properties of soils. Research shows, gypsum in addition to other stabilization materials such as bagasse ash, rice husk, lime, NaCl, tin, fly ash, jute fibre etc. produce a better stabilized soil as compared to gypsum or any of this material as stand-alone stabilizer. Laboratory result after series of experiment to determine the Maximum Dry Density and Optimum Moisture Content, Unconfined compressive strength, California bearing ratio CBR and Atterberg limit values of the stabilized soil using gypsum with other additives, reveals that for effective soil stabilization with the use of gypsum and any other additives is a function of the type of soil being stabilized, nature of additives, percentage of applied additives, curing time, also the classification of the soil to stabilized. It is found that the use of these additives in proportion of each other, their percentage proportioned, curing time and the nature of soil, give different end point of stabilized soil.

“…Selain itu, Wulan Novita juga mengungkapkan bahwa salah satu metode untuk memperbaiki tanah pada daerah tersebut adalah dengan menggunakan Portland Cement Type. Ada juga penelitian yang dilakukan oleh (Roesyanto et al 2018) pada tanah di daerah PTP II, Patumbak, Deli Serdang, Sumatera Utara diklasifikasikan kedalam kelompok CL berdasarkan USCS dan diklasifikasikan sebagai A-5-4 berdasarkan sistem klasifikasi AASHTO, yaitu tanah lempung dengan plastisitas rendah, sehingga tanah tersebut berpotensi mengalami kembang susut tanah yang merugikan bangunan konstruksi di atasnya sehingga Roesyanto mengungkapkan bahwa metode stabilisasi menggunakan gypsum dan abu vulkanik dapat meningkatkan sifat keteknikan tanah (Panguriseng and Makassar 2018). Namun dari penelitian terdahulu belum ada yang melakukan penyelidikan tanah pada daerah Desa Sukorejo, Kecamatan Ngasem, Kabupaten Kediri.…”

Ngasem District, Kediri Regency is an area that is close to educational centers, shopping centers, and tourism areas, so it is suitable to build housing in the area. However, there were several residents' houses that were damaged, such as cracked floors and walls. One of the contributing factors is the condition of the soil. This study aims to conduct a soil investigation to determine the characteristics of the soil in the area by using laboratory tests including sieving gradation tests, atterberg limits, compaction and soil shear strength and the results show that the soil in the area is classified as SW-SC soil, namely well graded sand with a little clay mixture so it has low plasticity. In addition, the maximum dry unit weight was 1.76 gr/cm3, the optimum moisture content was 15.38% from the compaction test and the cohesion value was 0.894 kPa and the shear angle was 29.685° from the shear strength test. The results of this study can be useful in providing an overview of soil characteristics as a reference in construction projects.Keywords: soil characteristics, SW-SC soil, atterberg boundaries, Ngasem District

Volcanic ashes (VA) are one of the by-products of explosive volcanic eruptions. They can be used as a soil stabilizer due to their cementitious properties as an eco-friendly soil stabilization approach. In this study, the impact of VA as an additive material (up to 20%) was investigated on the behavior of a clayey soil under one-dimensional compression tests and uniaxial compression tests. To this aim, the VA percentage effect, curing conditions, i.e. the optimum moisture content (OMC) and saturated sample, and curing time, on the oedometer modulus, and the uniaxial compression strength (UCS) are investigated. Results show that the addition of VA increases the UCS continuously in saturated conditions. However, this improvement is considerable for 5% additional VA at the OMC state and it induces 325% improvement in UCS. The maximum improvement of UCS occurs at 20% addition of VA in saturated condition. It was also revealed that VA-soil mixtures are more sustainable at low stress levels and the oedometer modulus increases with the VA addition. A long-term curing time leads to an increase of the fabricated bonds due to the pozzolanic reaction. Additional VA has no significant effect on the consolidation parameters specifically for short-term curing time.
