high efficiency and good performance concrete breaking equipment

High Strain Dynamic Pile testing, Equipment, and Practice.

ABSTRACT. High strain PDA testing has become common for verification of capacity of both driven and bored piles. It also investigates other aspects of the installation of driven piles such as hammer efficiency and driving stresses. The high benefit of dynamic test results for the relatively low costs of the tests has resulted in widespread use.

High Performance Concrete - an overview | ScienceDirect Topics

Besides the production of high-performance concrete, superplasticizers are also commonly used in the production of high-workability concrete. With a slump value of 180–230 mm, high-workability concrete can be pumped rapidly over long distances, easily compacted in structures with highly congested reinforcement, and can even be self-compacting (i.e., requiring no external compaction effort).
