Aug 01, 2019 Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.

Core testing for strength. Cores are cut using a drill with a hollow barrel tipped with industrial diamonds. The whole rig has to be firmly fixed in position by weights, anchor bolts, vacuum pads or bracing against other parts of the structure.

Apr 01, 2018 The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved

Core Drill (Crushing Test Concrete is a concrete destructive test, which aims to know the compressive strength / quality of concrete by taking the sample of structure concrete on the field then press tested using concrete crusher press in the laboratory. Core Drill (Crushing Test Concrete) procedure is standardized by ASTM C39 standard.

The concrete core drilling machine is portable, but it is heavy and must be firmly supported and braced against the concrete to prevent relative movement which will result in a distorted or broken core, and a water supply is also necessary to lubricate the cutter. ... Special tests on core after crushing for strength: Sulphate attack, Cement ...
Read MoreNov 07, 2019 The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed.

Apr 19, 2014 Fig: Concrete Core. The strength of a concrete core test specimen depends on its shape, proportions and size. The influence of height/diameter (H/D) ratio on the recorded strength of cylinder is an established fact. Strength of core have to be related to the standard cylinder strengths, i.e. for H/D ratio of 2.

Sawing of the ends of concrete core The ends of core specimen shall be flat, and perpendicular to the longitudinal axis. Sawing should be such that prior to capping the following requirements are met: a) Projections, if any shall not extend more than 0.2 inch[5mm] above the end surfaces b) The end surfaces shall not depart from perpendicularity to the longitudinal axis by a slope of more than ...

Usually, core samples are taken using an 80mm to 100mm barrel, with greater diameter samples providing more reliable crush test results. However, because customer rarely want a large hole in their concrete, a compromise is struck between our wish for a larger more reliable sample and the clients wish for a smaller hole.

3.3 Concrete strength is affected by the location of the concrete in a structural element, with the concrete at the bottom tending to be stronger than the concrete at the top. Core strength is also affected by core orientation relative to the horizontal plane of the concrete as placed, with strength tending to be lower when measured parallel to the horizontal plane. 3 These factors shall be ...
