Earthquake shaking table at the National Technical University, Athens, Greece. There are different experimental techniques which can be used to test the response of structures and soil or rock slopes to verify their seismic performance. One of these is using an earthquake shaking table (a shaking table or shake table).
A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...
Concrete mixer. A concrete mixer (also cement mixer) is a device that homogeneously combines cement, aggregate (e.g. sand or gravel), and water to form concrete.A typical concrete mixer uses a revolving drum to mix the components.

The flow table test or slump-flow test is a method to determine consistency of fresh concrete. Flow table test is also used to identify transportable moisture limit of solid bulk cargoes. [ 1 ] It is used primarily for assessing concrete that is too fluid (workable) to be measured using the slump test , because the concrete will not retain its ...
Volumetric Concrete Mixer A volumetric concrete mixer. A volumetric concrete mixer (also known as volumetric mobile mixer) is a concrete mixer mounted on a truck or trailer that contains separate compartments for sand, stone, cement and water. On arrival at the job site, the machine mixes the materials to produce the exact amount of concrete ...
An internal concrete vibrator is a steel cylinder about the size of the handle of a baseball bat, with a hose or electrical cord attached to one end. The vibrator head is immersed in the wet concrete. [5] External concrete vibrators attach, via a bracket or clamp system, to the concrete forms.
