Guidelines For Concrete Mix Designs
Concrete Scarifier - Concrete Surface Preparation. Scarifiers, also called concrete planers or milling machines, remove concrete faster and aggressively than grinders . That's because they use the pummeling action of multi-tipped cutting wheels, or flails, that rotate at high speeds to chip away at the concrete surface.
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.
