If MEMORY TARGET is not set and PGA AGGREGATE TARGET is explicitly set to 0 then the value of PGA AGGREGATE LIMIT is set to 90 of the physical memory size minus the total SGA size In all cases the default PGA AGGREGATE LIMIT is at least 2GB and at least 3MB times the PROCESSES parameter and at least 5MB times the PROCESSES parameter for an Oracle RAC instance

Sieve analysis

A sieve analysis or gradation test is a practice or procedure used commonly used in civil engineering to assess the particle size distribution also called gradation of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass

What is the size of coarse aggregate used in concrete

When the size of aggregate is greater than 4 75 mm say 5 mm it is called coarse aggregate Graded aggregates are used for better particle packing The larger the size of aggregate lesser the cement required for same strength up to certain grade

What is the effect of coarse aggregate size in compressive

When we design mix the concrete its target strength is much less than the compressive strength of the aggregates used in the formation It can also be clearly seen in the mix design procedure that greater the maximum size of coarse aggregate use
