Concrete testing tools in the field: slump cone and empty cylinders Concrete Slump Tests. Concrete slump testing is used to evaluate the flow characteristics of freshly mixed concrete. To conduct a slump test, concrete is placed into an inverted cone in three stages, using a metal rod to tamp down the concrete after every stage.
Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates …
