“…Stabilisasi tanah adalah teknik yang dilakukan untuk mengubah sifat -sifat tanah dengan cara mencampur atau menggambungkan dengan bahan baru [11]. Proses stabilisasi tanah dapat dibagi menjadi tiga jenis yaitu stabilisasi secara mekanis, stabilisasi fisik dan stabilisasi secara kimiawi dengan manambah zat additive pada tanah lempung yang akan distabilisasi [12].…”

Roads with subgrades that have soft soil (clay) characteristics are a problem that often occurs in these soil conditions because they have a very low bearing capacity. This condition is if the road construction that is built on it will cause damage. As a result, soil subsidence is not uniform in soil conditions that have a low bearing capacity. The type of soil used in this study is clay soil taken from the Garuda Sakti km.13 Kampar district, Riau. The purpose of this study was to increase the bearing strength of the soil by stabilizing the clay soil with a mixture of 5%, 10%, 15%, 20%, of oil palm bunch ash mixture, and 10% cement to increase the value of the California Bearing Ratio (CBR). The method used is laboratory testing to get the CBR value which refers to the California Bearing Ratio (CBR) test using SNI 03-1744-2008. From the results of atterberg tests carried out, the higher the variation of oil palm bunch ash and cement on clay soil, the atterberg value tends to decrease. The liquid limit value (PL) is 57.93% -43.16% -24.94% and the plastic limit (LL) is 27.35% -24.94%, causing the plastic index value to decrease by 16.73%. The higher the percentage of oil palm bunch ash and cement mixed with clay soil, the better the mixed soil is due to the reduced plasticity in the original soil. Testing the maximum CBR value in the laboratory with a variation of 15% oil palm bunch ash and 10% cement by 70.5%, the CBR value obtained meets the General Specifications of Bina Marga CBR 6%. The addition of Palm Oil Bunch Ash and cement can increase the CBR value in clay soils. The more variations in the levels of Ash and cement, the CBR value of the clay soil will increase. In conclusion, the variation of 15% oil palm bunch ash and 10% cement resulted in a maximum CBR value of 70.5%.

“…Therefore, in the presence of a small amount of activator, a chemical reaction may occur to form cementitious compounds, which help improve the strength of subgrade soil [24,26]. Moreover, many researchers [5,[27][28][29][30][31][32] have conducted a lot of research on the strength of lime, fly ash and cement, cement, lime fly ash, marble powder, lime rice husk, and their applicability as road and subbase. Since then, many efforts have been made around the world to confirm the treatment mechanism of expansive subgrade soil in highway fields to carry out appropriate pavement design and construction [33][34][35].…”

The effectiveness of the use of waste fly ash (FA) and cement (OPC) in the stabilization of subgrade soils and the reasons likely to influence the degree of stabilization were investigated. Incorporating waste fly ash (FA) and cement (OPC) as additives leads to significant environmental and economic contributions to soil stabilization. This study involves laboratory tests to obtain the Atterberg limit, free swell index (FSI), the unconfined compressive strength (UCS), the California bearing ratio (CBR), and the scanning electron microscope (SEM). The test results for the subgrade soil illustrate that the Atterberg limit, plasticity index, and free swell index are decreasing with the addition of different proportions of fly ash and cement, i.e., 0%, 5%, 10%, 15%, and 20% and 0%, 2%, 4%, 6%, and 8%, respectively. The CBR value of untreated soil is 2.91%, while the best CBR value of fly ash and cement mixture treated soil is 10.12% (20% FA+8% OPC), which increases 71.34% from the initial value. The UCS of untreated soil is 86.88 kPa and treated soil with fly ash and cement attains a maximum value of 167.75 kPa (20% FA+8% OPC), i.e., increases by 48.20% from the initial value. The tests result show that the stability of a subgrade soil can be improved by adding fly ash and cement. While effectiveness and usability of waste FA and cement are cost-effective and environmentally friendly alternatives to expansive soil for pavement and any other foundation work in the future.

“…Out of the total production in India, approximately 85% is quarried from Rajasthan state generating roughly around 5-6 Million Metric Tons of MSD slurry every year. Various options, such as utilization in cement manufacturing (Aruntaş et al, 2010;Ashish et al, 2016;Khichi, 2017;Toubal Seghir et al, 2019), production of synthetic gypsum through chemical reaction (DOLEŽELOVÁ et al, 2017;Krejsová et al, 2019), utilization in road construction (Chandra et al, 2002;Rai et al, 2020) as a low cost binder, (Khan et al, 2020) or in brick manufacturing (Emir et al, 2011;Gencel et al, 2012;ur Rehman, 2014) have been explored to manage this huge inorganic waste in a productive manner. However, utilization of MDP for improving the quality of solar salt with simultaneous production of gypsum from high sulphate rich brines, such as Rajasthan lake brines has not been explored so far.…”

Marble industry worldwide produces large amount of non-degradable marble dust powder (MDP) waste during mining and processing stages. MDP mainly comprises of CaCO3 with small amounts of Mg, Fe or Si in various forms. In India, mainly in Rajasthan state, marble is quarried in huge amounts and MDP thus produced is collected improperly and dumped at any abandoned land or identified disposal sites leading to several environment hazards. On the other hand, the composition of sub soil/lake brines of Rajasthan is typical in nature as it does not have much Ca2+ and Mg2+ impurities but contains higher levels of SO42-. Therefore, the common salt (NaCl) produced from such brines is contaminated with Na2SO4 (8-30 wt%) depending upon SO42- concentration in the brine. Such a salt produced is neither suitable for edible purpose nor for industrial usage. Herein, we have reacted MDP with HCl, and the resulting solution (CaCl2 and MgCl2 slurry) is used in stoichiometric ratio of Ca2+ to SO42- in brines to produce high purity NaCl and gypsum (CaSO4·2H2O) via fractional crystallization. Remaining magnesium containing solution was reacted with Na2CO3 to prepare high purity light basic magnesium carbonate hydrate. Purity of crystallized NaCl, CaSO4·2H2O and MgCO3·6H2O has been ascertained through analytical and spectral methods (TGA, FTIR, P-XRD). Field emission scanning electron microscopy (FE-SEM) was used to elucidate morphology of crystals. The method reported for improving purity of NaCl along with CaSO4·2H2O and MgCO3·6H2O production from sulphate rich brines is simple and economic, and allow management of MDP generated in huge amounts, which poses problems of disposal and creates environment hazards.
