Jan 11, 2018· Something like replace a Vlookup with a CUBE formula to source a text value from a PowerPivot table where if 3 of the values are met, it returns a variable 4th value.

The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.

aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS The apparatus of the aggregate crushing value test .

The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value < 45% for aggregates used for concrete for nonwearing surfaces and <25% for wearing surfaces like runways and .

You take the number of cubes on one side multiplayed by the number of sides. for example, in the standard rubik cube there are 9 cubes on each side and 6 sides. 9 times 6 is 54 so there are 54 ...

Compression Machines. Humboldt's concrete compression frames are designed to handle the daily demands of testing concrete cylinders, beams, blocks and cubes. Humboldt's compression machines span a testing range from 30,000 to 500,000 lbs. (1112 to 2,224kN).

May 10, 2013· Compressive Strength Test on Concrete . Procedure Representative samples of concrete shall be taken and used for casting cubes 15 cm x 15 cm x 15 cm or cylindrical specimens of 15 cm dia x 30 cm long. The concrete shall be filled into the moulds in layers approximately 5 cm deep.

strain curve is used to evaluate the result of the test. The force at stage 6 in the figure 4 is the Flat Crush Test result. In this paper we call this FCT. peak or FCTmax. This is the highest force just before total collapse. The FCTmax value is divided by the surface size of the test piece to make it .

Specification :Aggregate Impact Value Test Apparatus is used for determining the aggregate impact value. The Sturdy Construction consists of a base and support columns to form a. rigid framework around the quick release trigger mechanism to ensure an effective free fall. of the hammer during test. The free fall can be adjusted through 380±5mm.

All Answers ( 21) It is based on the strength gain pace of the Ordinary Portland Cement or CEM I (of classical properties) concrete of appropriate composition, that gains about 70% of its 28day strength at 7 days, and gains about 85% of its final (at the end of about a year) strength at 28 days.

The testing of cubes is carried out on their three sides without packing. Thus three cubes are tested each time to find out the compressive strength at the end of 3 days and 7 days. The average value is then worked out. During the test, the load is to be applied uniformly at the rate of 350 kg/cm2 or 35 N/mm2.
