Please I'm in hurry. A certain contractor has been required to use 3/4 in nominal maximum size of *gravel in their concrete mix for a certain project. While looking for suppliers fortheir gravel, it is required to take a sample from the supplier. How much sampleshall be taken from supplier in kg?48 kg19 kg15 kgO24 kgO 12 kgWhich of the following sizes can be used as field sample for fine aggregatessubject to sieve analysis?O 1.00 kg1.20 kg1.10 kgO 10.0 kgReferring to ASTM C128, which of the following criteria have also been used onmaterials that do not readily slump as described by the following procedure?Fill the cone mold and use 10 drops of the tamper. Then add material two moretimes using 3 and 2 drops of tamper, respectively. level off the material evenwith the top of the mold, remove loose material from the base; and lift the moldvertically.OUsing Hard-Finish Paper TowelsO Provisional Surface TestO Colorimetric ProcedureO Provisional Cone TestWe learned that there are limitations on the quantity of material which may beretained on a particular sieve.

Any material to be sampled shall be visually inspected to determine discernible *variations. If this is the case, then any discernible variations which may benoted shall be subject to what?Separate samples shall be drawn from separate areas of the pile after establishinghomogeneityReject the material and request for another unit of material to be subject to sampling.Proceed to sampling without any corrective action as the nature of the material willstill be reflected by the sampling methodDiscard the material to be sampled as accurate sampling is not possible

Question

Accepted Answer

Option 3 is the correct answer

Any material to be sampled shall be visually inspected to determine discernible variations. If this is the case, then any discernible variations which may be noted shall be subject to what?
