The amount of boron waste increases year by year. There is an urgent demand to manage it in order to reduce the environmental impact. In this paper, boron waste was reused as an additive in road base material. Lime and cement were employed to stabilize the waste mixture. Mechanical performances of stabilized mixture were evaluated by experimental methods. A compaction test, an unconfined compressive test, an indirect tensile test, a modulus test, a drying shrinkage test, and a frost resistance test were carried out. Results indicated that mechanical strengths of lime-stabilized boron waste mixture (LSB) satisfy the requirements of road base when lime content is greater than 8%. LSB can only be applied in non-frozen regions as a result of its poor frost resistance. The lime–cement-stabilized mixture can be used in frozen regions when lime and cement contents are 8% and 5%, respectively. Aggregate reduces the drying shrinkage coefficient effectively. Thus, aggregate is suggested for mixture stabilization properly. This work provides a proposal for the management of boron waste.

“…According to Maneli et al [19], the stabilized soil showed a great improvement in the UCC values and this behavior could be due to the pozzolanic reactions that occurred in the stabilized soil. This can be attributed to the chemical reactions between the soil and the additives which form cementitious materials which could reduce the volume of the voids and improve the compressive strength.…”

“…The rigidity of treated soil got increased compared to the untreated soil by the reduction in void ratios. Soil with less swell characteristics is suitable for construction, hence, the soil nature has improved by the addition of sludge [19,34].…”

“…Also, a higher density will reduce the permeability of the soil, thereby diminishing the moisture-carrying capacity or OMC, thus implementing less seepage of water. The main role of the compaction test is the densification of soil voids, thereby increasing the strength of soil [19,34,35].…”

“…One of such expansive soil is the black cotton soils which are generally found in land sliding areas. Such soils have high plasticity, low strength, and stronger swelling [19][20][21]. Hence, soil stabilization is an ideal technique to improve the soil properties, which can be undertaken by the addition of several admixtures [19][20][21][22].…”

Electrocoagulation Technique for Cephalothin Sodium Removal with Effective Sludge Management

et al. 2021

View full text Add to dashboard Cite

The electrocoagulation technique is applied for the treatment of hazardous cephalothin sodium antibiotic wastewater. The interaction effects of the various parameters on the maximization of removal efficiency and minimization of energy consumption are evaluated through multivariable optimization. The disposal of sludge is effectively performed by soil stabilization. Scanning electron microscopy analysis of soil fused with sludge shows an ordered arrangement with reduced void space. The improvement of soil properties is confirmed by the change in soil expansiveness from low to moderate region and by an increase in compressive strength.
