Students have asked these similar questions
A stud had dimensions of 38 mm * 89 mm * 2.438 m and a moisture content of 150% when it was prepared. After seasoning, the moisture content was reduced to 7%. If the tangential, radial, and longitudinal directions of the grains are on the same order as the dimensions indicated above, what are the dimensions of the seasoned stud if the moisture-shrinkage relation follows the below Figure ?
A sieve analysis test was performed on a sample of coarse aggregate and produced the following results. Referring to ASTM C33, what is the closest size number, and does it meet the gradation for that standard size?
Students in the materials lab performed the specific gravity and absorption test (ASTM C127) on coarse aggregate and they
obtained following data:
a. Dry weight = 3862.1 g
b. SSD weight = 3923.4 g
c. Submerged weight = 2452.1 g
1. Calculate the specific gravity values (dry bulk, SSD, and apparent) and the absorption of the coarse aggregate. (Answer in 3
