Prospective usage of magnesium potassium phosphate cement combined with Bougainvillea alba derived biochar to reduce Pb bioavailability in soil and its uptake by Spinacia oleracea L

Iqbal Naeem et al.

Summary: The study found that using MC alone effectively immobilizes Pb in soil and reduces its distribution in plants, while BR alone stimulates soil enzymatic activities and plant growth but is less effective in immobilizing Pb. A 50:50 ratio mixture of BR and MC showed the most promising outcomes, enhancing Pb-IMMi, soil enzymatic activities, plant growth, and reducing Pb concentrations in plants compared to control. Such a combination presents a cost-effective approach for reducing Pb uptake by plants.

Influence of rice husk ash, lime and cement on compaction and strength properties of copper slag

Kuldeep Sharma et al.

Summary: The study found that with the increase in the percentage of RHA, L and C, the MDD, specific gravity, and UCS of the mixture decreased, while that of copper slag decreased. However, there was an improvement in UCS value with the increase in curing period. A multilinear linear regression analysis helped identify the optimum mix composition.

Immobilization and leaching characteristics of fluoride from phosphogypsum-based cemented paste backfill

Qiu-song Chen et al.

Summary: The study evaluated the feasibility of using cemented paste backfill for the remediation of phosphogypsum and examined fluorine immobilization mechanisms. Through physico-chemical analyses, it was discovered that calcium silicate hydrate gel is associated with fluorine retention. However, further modifications are needed for the simulation to be used as a predictive tool for phosphogypsum management options.

Copper slag: The leaching behavior of heavy metals and its applicability as a supplementary cementitious material

Rongxing He et al.

Summary: The study found that the leaching concentration of heavy metals in copper slag was highest under acidic conditions but decreased with increasing pH. Additionally, copper slag showed great potential as an SCM, and the addition of copper slag to concrete reduced the overall compressive strength.
