of the overall limit of ASTM C33-03 30 are listed in Table3. For the coarse aggregate three CAMZs were used (CAMZ = 9.5 mm 19 mm and 37.5 mm) namely G10 G19 and G38 respectively. The sieve analysis of the coarse aggregates is listed in Table4. This table shows that the grading of the coarse aggregate was within the ASTM C33-03 30 limits.

2. Immerse the aggregate in water at room temperature for a period of 15 to 19 hours. Note 3 When testing coarse aggregate of large nominal maximum size requiring large test samples it may be more convenient to perform the test on two or more subsamples and then combine the values obtained. 3.

• Sieve analysis of fine and coarse aggregateGrade Valley

A test sample of the fine aggregate was weighed as shown in step 1 in test 1. The sieve sizes used for this test were #4 #8 #16 #30 #50 and #100. The sieves were arranged in an ascending order so as to compute the finest modulus. Steps 3 to 8 in test I were followed and the determined values recorded in table 2.
