In the context of disposal spent radioactive fuel, heat-emitting radionuclides such as Cs and Sr are utmost concern, they have a major influence on distance at which galleries should be spaced apart and, thus, cost facility. Therefore, certain scenarios investigate partitioning transmutation fuel to optimize disposability both Cs- Sr-rich waste streams remaining fractions. this study, stream, nitrate-based solution, was immobilized in metakaolin blast furnace slag-based alkali-activated...
This study investigated the leaching resistance of alkali activated slag mortars (AAS) under immersion in a 6 M NH4NO3 solution for duration up to 28 days, taking into consideration effect water-to-binder (w/b) ratio. SEM-EDS analysis revealed decalcification, desodiumization, and dealumination AASs during leaching, leading changes microstructure micro-mechanical properties materials. A combination N2-adsorption MIP demonstrated that there was coarsening structure an increase porosity along...
The study of Ca-leaching cement-based materials has necessitated the use accelerated leaching experiments because extremely slow kinetics. microstructural and mineralogical changes resulting from such are typically studied using Mercury intrusion porosimetry (MIP) Thermal gravimetric analysis (TGA), respectively. This paper closely examines pitfalls associated with applying these techniques to behaviour leached materials. In this context, cement paste samples two water/cement ratios (0.325...
Carbonation of alkali activated materials is one the main deteriorations affecting their durability. However, current understanding structural alteration these exposed to an environment inducing carbonation at nano/micro scale remains limited. This study examined evolution phase assemblages slag mortars subjected accelerated (1% CO2, 60% relative humidity, up 28 day carbonation) using XRD, FTIR and 29Si, 27Al, 23Na MAS NMR. Samples with three water binder (w/b) ratios (0.35, 0.45, 0.55) were...
This study examined the effectiveness of zeolite addition to reduce autogenous shrinkage high-performance cement-based concrete (HPC). The zeolites were replaced up 15% cement content by weight and their mean particle size varied from 5.6 16.7 µm. To evaluate crack resistance HPC containing zeolites, ring tests internal relative humidity measurements performed at different ages. compressive strengths determined 3, 7, 28 90 days curing. Test results confirmed that was promising favourable in...
Geopolymers and other alkali-activated materials were investigated in detail as alternatives to ordinary Portland cement because of their reduced CO2 emissions, high (radionuclide) binding capacities, low permeabilities. The last two properties make them potential for the immobilization several types chemical waste. In this context, direct liquid waste streams would be a useful application. This study aimed develop geopolymers with water-to-binder ratios, but good mechanical strengths, while...
<title>Abstract</title> The RILEM TC 281–CCC ‘‘Carbonation of concrete with supplementary cementitious materials’’ conducted a study on the effects materials (SCMs) carbonation rate blended cement concretes and mortars. In this context, comprehensive database has been established, consisting 1044 mortar mixes their associated depth data over time. dataset comprises mix designs large variety binders up to 94% SCMs, collected from literature as well unpublished testing reports. includes...
