Granular coal combustion products are problematic waste materials whose use as aggregates in concrete has been extensively studied. However, its integration into other non-structural and elements not so widely documented. Masonry mortars, precast masonry units with different ratios of bottom ash replacing conventional have With the incorporation workability, density strength decrease whereas po...

The impacts of climate change are inevitable and driven by increased levels greenhouse gases (GHG) in the atmosphere, requiring mitigation re-adaptation measures. In this context, article critically analyzes influence drying technology type, forest biomass, GHG emissions resulting from energy required for agricultural crops, presenting a case study tobacco drying. study, increasing technologica...

Abstract The performances of expanded clay aggregate and wood ash as internal curing water reservoirs were studied in the mortar phase a hypothetical high performance concrete with low water-to-binder ratio. two materials substituted 15 30% sand volume. Two different binders, Portland cement high-volume fly blended cement, used. compressive strength volume stability mortars sealed air-drying co...

The time course of isocyanate emission from curing PUR-adhesives was studied in an emission test chamber. The adhesives under investigation were commercial products for fixing of textile floor coverings and based on methylene bisphenyl diisocyanate (MDI). Influence of the curing mechanism was studied by comparing the emission curves of one-component adhesive (OCA) and two-component adhesive (TC...

This investigation aims at determining the microhardness value of the hybrid direct/indirect composite resins submitted to conventional light curing and post-cured using two different methods, a light source from a laboratory light curing unit and a conventional oven heating, and the obtained results were compare to an indirect composite resin. A hybrid direct/indirect composite resin (Filtek P...

In this study, the reduction of early-age strength mortar caused by traditional super absorbent polymer (SAP) was solved. Two types alkanolamines (Alkanolamine-A and alkanolamine-B) calcium nitrite were compounded with SAP as components then added into to evaluate effects on drying shrinkage. Results showed that adding two could significantly improve compressive mortar. The addition refine pore...

Soil moisture depletion during the growing season can induce plant water stress, thereby driving declines in grassland fuel and accelerating curing. These drying curing dynamics their dependencies on soil are inadequately represented fire danger models. To elucidate these relationships, fuelbed characteristics were monitored nine patches of tallgrass prairie under patch-burn management Oklahoma...

Improper curing of onion bulbs leads to high losses during storage. The aim is seal the by drying its outer scales and neck, limiting weight loss. A coupled heat mass transfer model was established for prediction moisture temperature distribution inside bulbs. finite element method used discretising governing equations transient transfer. predicted results were compared with experimental data p...

This paper compares the alkali-activated fly ash (AAFA) manufactured with thermal oven curing and pulsed microwave curing methods. Fly ash activated by 8M NaOH solution at a liquid to solid ratio of 0.3 was cured by thermal oven at 85°C and domestic microwave oven, respectively. Apart from compressive strength test, the temperature profiles of AAFA samples were captured by thermal camera. React...
