Three cubes shall be taken from fresh concrete delivered on site and tested at 28 days age. Like water permeability test, this is also one of the tests to determine the durability of concrete. The frequency of the water permeability test can be found in this article The Frequency of Various Tests. This kind of test shall be taken from substructures concrete elements like foundations, concrete water tank, retaining wall etc. Three cubes shall be taken from fresh concrete and tested in accordance with the German Standard DIN 1048 at 28 days age. Water Permeability testДЄ water permeability test is one of the tests to determine the durability of concrete.

You might ask why again, because if the concrete cubeВ fails at 28 days the concrete cubes might be having a slow gaining strength, but the required strength might be achieved after 60 days, especially those concrete having pozzolanic cement and cement replacementВ that has GGBS and FA.

This one sample extra shall be tested вЂњif!вЂќ the two cubes or cylinders samples are tested from the three and if it is failed and the remaining sample is passed. You might ask why sometimes there is extra of one sample? Good that you asked. Three samples of cubes or cylinders shall be taken for compressive strength test, but it is not commonly three samples, sometimes it is two depend on the specification. It means that the drop of concrete after the slump cone is removed should not be more than 175 mm nor less than 125 mm. Let say for example the slump of approved concrete design mix for your suspended slab is 150 mm +/- 25.

The plus or minus sign is the symbol of tolerance of slump. You might ask вЂњWhat is a slump?вЂќ And вЂњWhy there is plus or minus sign (+/-) in the slump?вЂќ You may go ahead with this article The definition of construction terms to see the meaning of slump. Three cubes or cylinders of samples shall be taken for compressive strength tests, these will be the samples from the site. Upon arrival on site, a sample of fresh concrete shall be tested with slump test again, but temperature shall be checked with the calibrated thermometer beforehand.

After batchingВ the concrete, a sample of fresh concrete shall be taken to test for slump tests and the samples for compressive strength test be taken too. This is to determine the workability of concrete in terms of slump test. Slump test before leaving the batching plant and on arrival on site Here are 6 common quality tests on concrete before and after completion of casting on site. In order to determine the quality of concrete on site, it shall undergo quality tests. вЂњ Concrete is a composite material that consists essentially of a binding medium within which are embedded particles or fragments of aggregates, usually a combination of fine aggregates and coarse aggregates in Portland-cement concrete, the binder is a mixture of a Portland-cement and water, with or without admixtures.вЂќ
