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.
This aggregate is useful in most concrete mixes, and is well indurated and harder than virgin aggregates due to the uniform process of Blue Planet's reformation step. While our Upcycled Aggregate does not directly sequester CO2, it offers significant benefit compared to virgin aggregate by adding recycled content value, and the avoidance of CO2 related to mining and transportation.

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
