Performance of Eggshell Powder Addition to Clay Soil for Stabilization

Abstract

Abstract: The behavior of clay soil often becomes problematic for the building above it. One problem is its shrinking and swelling behavior which is affected by its water content, which also frequently influences the soil bearing of capacity in holding the load of the building above it. The powder from eggshell which abbreviated as ESP is a food industry waste that is high calcium and not often used for reprocessing. This experiment purposes is to know the effect of adding ESP as a stabilizing material in clay. Soil sample for laboratory testing was carried out from Cot Bagie Village, Blang Bintang, Aceh Besar District, and Aceh Province. From AASHTO classification system, the soil sample is A-7-5 (21) and from USCS system, is organic clay with high plasticity (OH). The percentages of ESP added are 0%, 3%, 6% and 9% of the dry weight of the clay for experiment on laboratory. The Atterberg Limit parameters commonly incline with ESP addition. Based on the standard Proctor test, the original soil has an Optimum Moisture Content (OMC) of 19.8% and a maximum dry unit weight (γ d max ) of 1.367 gr/cm 3 . Overall, adding ESP to the clay sample increases the mechanical properties of soil compared to the sample without ESP. Thus, the use of ESP for stabilization in this experiment can improve the bearing capacity, so that it is beneficial for construction in the field.

Pengaruh Penambahan Serbuk Karet dan Serbuk Cangkang Telur Terhadap Parameter Tanah Lempung pada Pengujian Konsolidasi dan Kuat Geser Langsung

“…Berdasarkan penelitian (Munirwan & Jaya, 2019), penggunaan ESP dengan kadar optimum 3% untuk stabilisasi tanah berdasarkan penelitian eksperimen laboratorium dapat meningkatkan daya dukung tanah menjadi lebih baik sehingga bermanfaat untuk konstruksi di lapangan.…”

“…Variasi kadar campuran serbuk karet yang ditambahkan pada tanah lempung adalah 9%, 12%, (Nurfatihah, Sri Wulandari) dan 15%. Sedangkan, untuk kadar serbuk cangkang telur sendiri diambil berdasarkan penelitian sebelumnya(Munirwan & Jaya, 2019) yang menyatakan bahwa penambahan serbuk cangkang telur paling optimum adalah dengan kadar sebesar 3%. Pengujian-pengujian yang dilakukan di laboratorium diantaranya pengujian indeks properties (uji kadar air, uji berat isi tanah, uji berat jenis tanah, serta uji Atterberg limits [batas plastis, batas plastis, dan batas susut]) dan engineering properties (uji konsolidasi dan uji kuat geser langsung).…”

Development of Eco-Friendly Mortars Produced with Blast Furnace Slag, Calcined Eggshell and Brick Waste: Mechanical Behavior and Microstructure Assessment

“…Many studies are focused on the use of eggshell waste in civil engineering applications. It has been reported that calcined eggshell is used as an alternative for a clayey soil stabilizing agent that replaces quicklime lime to improve soil properties [19]. Eggshell can be used as accelerator to reduce the cure time of the rigid road pavement in the peak of rainy seasons [20].…”
