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 ...
