Question
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 for their gravel, it is required to take a sample from the supplier. How much sample shall be taken from supplier in kg? 48 kg 19 kg 15 kg O24 kg O 12 kg Which of the following sizes can be used as field sample for fine aggregates subject to sieve analysis? O 1.00 kg 1.20 kg 1.10 kg O 10.0 kg Referring to ASTM C128, which of the following criteria have also been used on materials 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 more times using 3 and 2 drops of tamper, respectively. level off the material even with the top of the mold, remove loose material from the base; and lift the mold vertically. OUsing Hard-Finish Paper Towels O Provisional Surface Test O Colorimetric Procedure O Provisional Cone Test We learned that there are limitations on the quantity of material which may be retained on a particular sieve. This is to ensure that all particles will have opportunity to reach sieve openings a number of times during the sieving operation. What is the allowed quantity of material that can be retained on a 25.0 mm sieve? Assume that the sieve has a 10-in diameter. O 2.9 kg 4.2 kg 3.2 kg 6.3 kg We learned that there are limitations on the quantity of material which may be retained on a particular sieve. This is to ensure that all particles will have opportunity to reach sieve openings a number of times during the sieving operation. What is the allowed quantity of material that can be retained on a 25.0 mm sieve? Assume that the sieve has a 12-in diameter.

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? Separate samples shall be drawn from separate areas of the pile after establishing homogeneity Reject 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 will still be reflected by the sampling method Discard the material to be sampled as accurate sampling is not possible
