activators increased the sulfate attack resistance of alkali-activated y ash and slag cement in a MgSO 4 solution Bakharev 2005 Shi et al. 2006 while steam curing of specimens made with water-glass with a modulus from 1 to 3 decreased the sulfate attack resistance compared to the specimens cured under normal conditions Shi et al. 2006.
1 Scope. This International Standard specifies a method for the determination of the alkali-insoluble fraction of pulps using sodium hydroxide solution of fixed concentration. The sodium hydroxide concentrations most frequently used are 18, 10, and 5 mm .

Battery-powered, highly portable oxygen concentrators are a growing trend in patient mobility, enabling more and more oxygen-dependent patients to leave behind bulky home oxygen concentrator systems larger, older portable concentrators or oxygen tanks for hours at a time. But creating and building devices with high oxygen capacity in a size and weight easily managed by an oxygen ...
Table concentrator, which is also called shaking table or concentrator table is a mine selecting machine for fine materials working by gravity. Shaking concentrator is widely used in the selection of tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, iron, manganese, ferrotitanium and coal. Hongxing Machinery has long history of ...
For Nickel alloy 200, the availability of chlorates in caustic soda increases the corrosion rates.Due its concentration of chromium, Inconel alloy 600 is fully resistant to corrosion by ammonia for a complete range of concentrations and temperatures. Inconel alloys 622, 625, C276 and 686. While these provide outstanding corrosion resistance, Nickel-chromium-molybdenum alloys are not usually ...
degradation mechanisms of sulfate attack SA and alkali silica reaction ASR are addressed in this study. The effect of fly ash in changing the sulfate attack and Alkali-Silica resistance of concrete for a range of replacement 10-40 of Class F and Class C fly ashes was determined using both experimental and theoretical modeling.
Nov 21, 2014 The consequence of sulfate attack on geopolymer concrete, made from an alkali activated natural pozzolan AANP has been studied in this paper. Changes in the compressive strength, expansion and capillary water absorption of specimens have been investigated combined with phases determination by means of X-ray diffraction. At the end of present investigation which was to evaluate

2.3.4. Acid and alkali resistance test The acid and alkali resistance of the coatings with and without 2.5 wt. nano R-SiO 2 was tested by immersing in 5 HCl solution and 5 NaOH solution according to the standard JIS K 5400-1990. The decline of the samples was assessed by IR, FE-SEM and weight loss analysis. 3. RESULTS AND DISCUSSION

The glass surface is boiled for 3 hours to determine alkali resistance. The aqueous solution used must consist of equal parts caustic soda c NaOH1 moll and sodium carbonate c Na2CO30,5 moll. If the weight loss of the glass after 3 hours of boiling comes to 75 mg100cm2, the glass is Alkali-resistance

The results of untreated and alkali-treated specimens tensile-tested are shown in Table 1, in which the values are all averages. The results showed that the tensile strength of curaua fibers obviously decreased by alkali treatment. This fact could be due to damage on the fibers caused by chemical reaction with sodium hydroxide during treatment.
