The amount of released chloride ion is dependent on the W/B ratio, content of total chloride ions and temperature range.
Several chemical parameters including pH value, soluble chemical oxygen demand (COD), and volatile fatty acids and total inorganic carbon (VFA/TIC) ratio (content of volatile fatty acids to total inorganic carbon) were also measured in the samples.
The mixture composition includes binder type and content, supplementary cementitious materials, fillers, water-to-cementitious ratio, content and characteristics of coarse aggregate, paste volume, chemical admixtures, concrete unit weight, concrete consistency, and temperature.
The mix parameters analysed through a laboratory experiment of 54 different mortar mixes were, sodium silicate/sodium hydroxide mass ratio (2.5, 3.5, 4.5), activator/binder mass ratio (0.6, 0.8, 1.0), chemical foaming agent type (hydrogen peroxide (H2O2) and sodium perborate (NaBO3)) and foaming agent mass ratio content (1%, 2%, 3%).
The model was calibrated successfully to capture the carbon content and the C-to-N ratio content of the pools comprising the three aggregate types (macro-aggregates: > 250 μm, micro-aggregates: 53 250 μm, silt clay sized aggregates: < 53 μm) in both sites.
To achieve this goal, a set of steady-state Fischer Tropsch runs has been carried out in a lab-scale reactor loaded with a 20 wt.% Co/Al2O3 catalyst, investigating the effects of the main process conditions (temperature, H2/CO inlet ratio, content of inert gas in the feed, syngas space velocity) on the reactants conversion and on the C1 C50 product selectivity.
Peering agreements and negotiations are typically shrouded in secrecy, yet peering disputes between high-profile nodes over traffic ratios, content types, and peering conditions often generate attention.
Results also showed that the VS/TS ratio, lignin content, and hemicellulose content exerted a combined influence on the methane yield.
Collectively, the VS/TS ratio, lignin content, and hemicellulose content were important but not the only factors determining methane yield in anaerobic digestion.
Mass loss in litterbags at urban and periurban sites was significantly and negatively correlated to ADL N ratio, phosphorus content, and chrome content of initial litter.
The data used in NN model are arranged in a format of seven input parameters that cover the water to binder ratio, water content, fine aggregate ratio, fly ash content, air entraining agent, superplasticizer and silica fume replacement.
