12) Record the reading and correct it by using the Standard Sulfate Solution Correction Curve. 13) Corrected reading multiplied by final dilution = ppm, divide ppm by 10,000 to get % sulfate by the mass. 14) If the reading exceeds the limits of the meter or the maximum value of the meter is displayed, discard the test sample and sthe blank. Clean the sample cells. Dilute sample further by theTesting of industrial products - Aggregates for construction,The test method requires masses to be determined to the nearest 0.1mg, so that the above precision is achievable in the weighings, but clearly great care needs to be taken if this precision is to be achieved when maturing, filtering and igniting the precipitate.BS 812-118:1988 - Testing aggregates. Methods for,,For practical purposes for aggregates in concrete, the total sulphate content determined by this method is taken to be the same as the total water-soluble sulphate content. Two procedures for a semi-quantitative test are described in an appendix to this standard.
8.4 Calculate concentration of sulfate ions in the original soil sample: 4 R DF Fl SO W ×× = Where: SO4 = concentration of sulfate ions in the original soil sample, ppm R = concentration of sulfate ions in the sample run through the ion chromatograph, ppm DF = dilution factor Fl = volume of the flask containing undiluted sample, mLTesting of industrial products - Aggregates for,This report gives the results of a cross-testing experiment on the determination of the acid-soluble sulfate content of aggregates involving 12 laboratories from 9 countries. The materials used in the experiment were a concreting sand, a recycled concrete, and a blast-furnace slag. The results of the experiments show that the reproducibility of the test is not good enough for it to be used as,DETERMINATION OF SOLUBLE SULPHATE CONTENT IN,07.05.2015· Take the soil sample in a state in which it can be crumbled. If necessary, dry it in oven at 105 0 C to 110 0 C. Break the lumps in a mortar with a rubber covered pebble. Mix the sample thoroughly and sub-divide it by quartering. Take 10 g of soil from the sample in a 250 ml bottle with 100ml of distilled water.

Also, in the UK, sulfate problems caused by naturally occurring aggregates are rare. Where an new source or material is to be considered or is suspected of containing sulfate, it should be assessed before being used. Note, some Standards quote Sulfate as SO 4.

This British Standard, a part of the BS 812 series, describes two methods for determining the sulphate content of aggregates. The first method determines the water-soluble sulphate content of aggregates, which applies to natural and synthetic aggregates to be used as drainage materials or for fill or hard core, e.g. unbound road bases or sub-bases or foundations.Standard Test Method for Water-Soluble Sulfate in Soil,C114 Test Methods for Chemical Analysis of Hydraulic Cement.

A sulfate standard was prepared of gypsum and barite (each ground to pass a 100-rnesh sieve) mixed in the ratio 3:1. This was carefully analyzed for sulfate content. Twelve of the more common sulfide minerals were also prepared as standards. After grinding to pass 100-mesh sieve each was treated with 1 percent hydro chloric acid at room temperature,
