As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Strength of concrete cube is inversely proportional to, quarry, aggregate, and different kinds of minerals.
Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.
STRENGTH OF CONCRETE ( Page 6, clause 1.9.1)- Substitute the following for the existing clause: '2.9.1 Cube Moulds - The mould shall be of 150 mm size conforming to IS J0086 : 1982*.' ( Page 6 ) - Insert the following foot-noteat the bottom: '.Specification for moulds for use in tests of cement and concrete.'
1. In general, a lot of literature is available on compressive strength of cube or cylinder specimens. However, in practice, reinforced concrete is used in the field, especially for large structures.
Nov 29, 1999· The cubes have been loaded onto the crushing rig with the loading platten centered on the high front edge. The purpose of this is to encourage the leading edge to begin to crush so that the top of the leading edge flattens and the breadth of the loaded edge increases as the concrete continues to crush …

The cubes should be covered with a damp cloth and a plastic sheet and stored in dry environment at a temperature range of 20 ± 5 degrees. The concrete cubes are removed from the moulds a minimum 16 hours later to a maximum 72 hours, usually this done after 24 hours. Make sure the cube ID is transferred to the cube before placing into a curing ...
Concrete Compression Testing. Concrete strength is measured by crushing concrete cubes or cylinders to failure and recording this strength. VJ Tech designs and manufactures Automatic and Semi-Automatic Concrete Compression Testing Equipment with loading capacities for either 2000 kPa or 3000 kPa, together with all acccessories required.
The strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting).
