Concrete Penetrometer Concrete Penetrometer Introduction This test is used to determine the elapsed time between batching of a concrete sample and when it is deemed by standard methods to have set. The method involves measuring the penetration resistance of a test sample, which has had coarse particles removed at periodic intervals. It is particularly useful, …
Concrete Mixer – Laboratory Type Concrete Mixer – Laboratory Type Introduction A concrete mixer is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. The mixer uses a revolving drum to mix the components. Uniform and thoroughly mixed batches can be produced in field or Laboratory. Inevitable …

Needle Vibrator Needle Vibrator Introduction In the process of compaction, efforts are only directed to reduce voids in the compacted concrete. The Vibrators produce vibrations which when transmitted to plastic concrete make it to flow and affect compaction. The air bubbles are forced out of concrete due to vibrations. The Needle Vibrator, also known as …
