The effect of alkali content (% K2O + %Na2O) on the mechanical properties of alkali activated blast furnace paste has been investigated. The paper presents the study on workability, compressive strength, split tensile strength and microstructure of alkali activated blast furnace slag paste specimens prepared by using of sodium silicate and potassium hydroxide solution as activators. The experim...

1,2,3,4-Butane tetracarboxylic acid (BTCA)-treated cotton fabrics were immersed in alkali for increasing time periods and the effectiveness of alkali in removing the cross-linking agent was investigated by surface (X-ray photoelectron spectroscopy, XPS) analysis, attenuated total reflectance Fourier transform infrared spectroscopy and solubility in specific solvents. The cellulose yield after t...

The alkali preparation of the root and fresh leaf juice of Moringa oleifera possessed significant dose -depen-dent anti-ulcer activity in experimentally induced acute gastric ulcers with aspirin, the anti-ulcer effect of the alkali preparation of the root seems to be more pronounced than that of the fresh leaf juice. Te anti-ulcer activity of the alkali preparation of the root could be due to i...

Saline-alkali land is the main reserve soil resource. The amount of arable farmland can be increased through improvement and utilization saline-alkali land. Bio-organic fertilizer an effective conditioner, but there are few studies on with traditional Chinese medicine residues (TCMRs). In this study, organic made from Ganoderma lucidum residue (GLR) was mixed at different proportions; physicoch...

The alkali-metal ions, Li+, Na+ and K+, exhibit complex pH-dependent effects on sucrase that seem to involve at least three separate types of mechanism and, perhaps, an equal number of specific metal-binding sites. In metal-free buffers, the alkali metals give mixed activating effects below pH 7 that involve: 1) Affinitytype (K-type) activation kinetics, where the apparent K,,, decreases as the...

In this study, the nature of electrical transport and structural changes resulting from systematic substitution Al2O3 with K2O in 40P2O5-(25−x)Al2O3-35Na2O-xK2O, where x = 5.0, 7.5, 10.0, 12.5, 15.0 mol% (PANxK), is investigated. The impact glass structure its correlation to properties presented. mixed alkali effect (MAE) observed due presence two different oxides, a non-monotonic trend studied...
