Cement Standards and Concrete Standards

ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

Analysis of total chloride content in concrete ScienceDirect

Total chloride or acid-soluble chloride in concrete depends on the chloride content in concrete mix ingredients. The precise amount of chloride that is contributed by each element of the concrete mix compositions is hard to be defined because the chloride contents in aggregate and in concrete mixture as a whole are not equally distributed.

Aggregates for Concrete as per American Standards ASTM

The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates.

Sulfate attack in concrete Cement

Sulfate attack in concrete and mortar. Sulfate attack can be 'external' or 'internal'. External: due to penetration of sulfates in solution, in groundwater for example, into the concrete from outside. Internal: due to a soluble source being incorporated into the concrete at the time of mixing, gypsum in the aggregate, for example. External sulfate attack
