Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory, concrete and aggregate testing by an independent third-party is necessary to help assure compliance.
Crushed Concrete Aggregate Concrete Construction Magazine
Jun 30, 2011Crushing old concrete to make aggregate for new concrete is increasing in popularity for several reasons. Owners want projects to be sustainable and LEED certified. Recycled concrete qualifies for recycled material credits, and because it usually is found locally, it qualifies for local credits.
I realized the reason is that ROBOT reports the concrete strength based on the cylinder crushing strength whilst the British codes designate the concrete based on cube crushing strength, hence C35 (from British material database)
9.2 Crushing Strength of Concrete 9.2.1 Introduction
concrete production so that the concrete very rarely fails in crushing strength tests. Crushing strength tests may be carried out on either cylinders or cubes made in standard moulds, cured under standard conditions and crushed in a standard manner. Any variations in the methods of manufacture, curing or testing may affect
Concrete Cube Testing Concrete Testing Solutions UK
Concrete cube testing is a simple, cost-effective test of the compressive strength of concrete, providing you peace of mind that your concrete is fit for purpose and in line with BS EN 12390. Concrete samples are taken from the concrete truck while being poured and
Why do we weigh the weight of concrete cubes before
Sep 21, 2017Why do we weigh the weight of concrete cubes before crushing to a compression machine? I'd have said that we "record" the weight, or "determine" the weight. Or "mass", even. But putting that aside, the reason is that we want to know reasons why th

Concrete cubes may get crushed on one side or will develop tensile crack on one or more faces and fail. Fig shown below shows some of the likely unusual failures of concrete cubes. This type of failure will give lower indication of compressive strength of concrete. These are usually due to defects associated with testing machine.
Compressive Strength of Concrete Definition, Importance
Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concrete's ability to resist loads which tend to compress it. The compressive strength is measured by crushing cylindrical concrete specimens in compression testing machine. The compressive strength of concrete is calculated by the failure load
Compressive Strength of Concrete Cube Test Procedure

There wasn't any wire or metal in the crushed concrete but we are learning is that you have to look at the material and see how much rock is in it. If the milled concrete is very fine without some rock in it, you might need to add a layer of crusher run on top of it to make sure you don't get too much dust or mud.
of the concrete but in no case shall the concrete be subjected to less than 35 strokes per layer for 150 mm cubes or 25 strokes per layer for 100 mm cubes, except in the case of very high workability concrete.
