This test method covers the determination of the water-soluble sulfate ion content in soil. This standard is divided into two parts. The first part specifies the procedure for sampling and preparing the sample to size for testing. The second part delineates two test procedures (Methods A or B) for the determination of the sulfate ion content in ...
Sulfate levels >200 ppm frequently indicate high concentrations of organic matter. Sulfate content may be determined in accordance with ASTM D 516 or equivalent. Sulfides . Sulfide levels > 0.10 ppm may indicate that sulfates have been reduced by bacteria. Sulfide content may be determined in accordance with EPA 0376.1 or equivalent. Particle Size
The sulfate concentration should be determined based on an accepted specification such as AASHTO T 290 (modified), which is discussed later in this report. Table 1 outlines the level of risk associated with stabilizing soils with varying sulfate concentrations (33). Table 1. Level of risk associated with lime stabilization in sulfate-bearing clays.
information on the sulfate content of Texas soils. However, this project found that the existing Geological Atlas of Texas can be used to detect areas which are rich in sulfates. These maps are being used in two current forensic investigations on U.S. 82 in the Paris District and IH 40 in the

ASTM C88-99: Soundness of Coarse Agg. ASTM C88-99: Moisture Content. ... Acid Soluble Sulphate Content of Concrete Dust Samples. BS 1881:124:88: Chloride ...
Because there are different types of sand – and each of those types of sand go by multiple names, it can be difficult to be sure that you're choosing the right material for your project. People tend to get especially confused when it comes to ASTM C33 sand materials. While this type of sand is very frequently used, it's important to ...
Feb 01, 1996· Q. We're designing a concrete structure in Egypt, and I received test results for the aggregate to be used in the concrete. The report lists chloride and sulfate content, but I don't know how to evaluate these numbers because ASTM C 33, "Standard Specification for Concrete Aggregates," doesn't give limits for them.
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.
4.1 Water-soluble chloride, if present in sufficient amount, is capable of initiating or accelerating the corrosion of some metallic materials embedded in or contacting cementitious mixtures such as mortar and concrete. Chloride content, along with other factors, can be indicators for the possibility of corrosion of embedded metallic materials. This test method is used to determine the water ...
