Study on the Design and Synergistic Mechanism of Nanoparticle Modified High-Content Biochar Composite Cementitious Materials Based on Response Surface Method

Опубликована: Янв. 1, 2025

The replacement of cement with biochar (BC) has been proven to be an effective approach for reducing carbon emissions and promoting the resource utilization solid waste. However, limitations on amount remain a significant challenge. This study aims enhance maximum substitution level BC through hydration regulation effects nano-titanium dioxide (NT) nano-silica (NS) particles.The response surface methodology (RSM) was employed optimize dosages BC, NT, NS, as well predict strength outcomes. model predictions were validated experiments, underlying mechanisms investigated. results showed that, at 8.1% 0.6% 1.8% high can achieved while ensuring mechanical performance cementitious material. Verification tests indicated that error between experimental predicted less than 5%. Microscopic analysis revealed combined effect NT NS promoted process BC-cement composite, refined size products, effectively filled pores in both matrices. also strengthened interfacial bonding surrounding products. At 28d, total porosity BC8.1NT0.6NS1.8 sample decreased by 27.9% 9.4% compared BC8.1 control groups, respectively, thereby enhancing overall densification composite

Porous Mortars Incorporating Active Biochar from Olive Stone Waste and Recycled Masonry Aggregate: Effects of Accelerated Carbonation Curing

Materials, Год журнала: 2025, Номер 18(4), С. 904 - 904

Опубликована: Фев. 19, 2025

This study investigated the use of activated biochar derived from olive stone waste and recycled masonry aggregates in porous mortar mixtures assessed their behaviour under accelerated carbonation curing conditions. Three were produced, incorporating 0%, 5%, 10% by volume. The physical, chemical, mechanical properties mortars analysed, including compressive strength, flexural water absorption, porosity, CO2 capture capacity. Additionally, calorimetry tests performed on cement pastes with 0.5%, 1%, 3%, 15%, 20% to evaluate impact setting times ensure compatibility between cement. results showed that addition improved properties, particularly curing, whereas active (AcB) significantly enhanced strengths. Furthermore, incorporation boosted efficiency, mix showing up 147% higher uptake, compared a control. These findings suggest can be effectively utilised develop sustainable construction materials thereby contribute carbon sequestration reduction environmental impacts. research fills gaps current knowledge stones cement-base
