Cover Story: The study focuses to the production of cement mortars using upgraded recycled concrete sand (Figure 1a) for total natural sand replacement and thermally activated recycled concrete fines as a partial cement substitution material. The combined usage of upgraded recycled concrete sand for total primary crushed sand (Figure 1b) replacement and recycled concrete fines as partial cement replacement material is a promising option to produce cement mortars.

Advances in Nanocarriers for Drug Delivery in Dental TherapiesAbstract Dental caries are one of the major causes of oral degeneration diseases. In order to treat dental-related diseases, it is often challenging and expensive. Recent literature has reported many advances in designing delivery systems utilizing polymers and novel biomaterials. Polymers play a [...] |
Assessment of AAR and Sulfate Attack on Wadi Gravel Concrete after 4 Years in ServiceAbstract Wadi gravel is a local aggregate in Qatar that could contribute to enhanced sustainability by replacing expensive imported gabbro. The material needs to be processed before use to reduce sulfate content to acceptable levels. The paper presents the performance assessment of three full-sca [...] |
Production of Fermentable Sugars from Cassava Stem using Hybrid Pretreatment TechnologyAbstract One of the crucial steps in the enzymatic hydrolysis of biomass is pretreatment. We investigated the applicability of a hybrid pretreatment method, This involved acid treatment followed by alkali before the production of fermentable sugars from cassava stem. The substrate was initially t [...] |
Phase Equilibrium in ZrO2-CeO2-Eu2O3 System at a Temperature of 1500 °CAbstract The phase equilibria and structural transformations in the ternary ZrO2-CeO2-Eu2O3 system at 1500 °C were studied by X-ray diffrac [...] |

Abstract Waste concrete is the most predominant constituent material among construction and demolition waste. Current waste concrete recycling is limited to the use of recycled concrete aggregates as a road-base material and less as aggregates in new concrete mixes. Further, the production of rec [...] |
Bisphenol A Release from Orthodontic Clear Aligners: An In-Vitro StudyAbstract Bisphenol A (BPA) is a widely used synthetic compound that has been identified as an endocrine disruptor. It has been linked to adverse health effects such as developmental defects, infertility in both men and women, cardiovascular disease, and obesity. There has been increased interest [...] |

Abstract The present study investigated the effect of reused rubber particles (RRP) on the deicer salt durability of ordinary concrete. Four mixtures were designed, a control concrete (CC) and three other rubber concretes obtained by partial substitution of natural dune sand aggregate with reused [...] |
Experimental and Statistical Evaluation of the Interaction Effect of Recycled Aggregate and Water/Cement Ratio on Concrete Compressive StrengthAbstract The production of concrete using recycled aggregates, obtained from the processing of construction and demolition waste, is extensively practiced worldwide. However, the effect of simultaneous adding fine recycled aggregate and the recycled coarse aggregate on the mechanical properties o [...] |
Influence of Biopolymers on the Mechanical Behavior of Earth-Based Building MaterialsAbstract Currently, the largest among the earth excavation sites in Europe are located in the Paris region. The soils excavated from these sites are often considered waste and are not valorized. With an increasing focus on sustainable development, the demand for low-carbon building materials is r [...] |
Assisted Phytostabilization of Acidic Polymetallic Mine Tailings Using Marble Waste and Native Plant Citrullus colocynthis: Effect on Soil, Plant, and Metal UptakeAbstract This study aimed to assess the effectiveness of the phytostabilization ability of the native Moroccan plant Citrullus colocynthis on the neutralization of soil acidity and stabilization of metallic trace elements (MTEs) assisted by marble waste. Mine tailings (MT) co [...] |
Drainage in a Screw Press and Utilization of the Recovered Fibres after Thermo-Hydrolytic Disintegration of Waste FibreboardsAbstract A thermo-hydrolytic disintegration process qualifies as a promising option for recycling the waste MDF and preserving the fibrous morphology of the recovered lignocellulosic fibre material. This study aims to include a drainage process between the thermo-hydrolytic disintegration and the [...] |
