اکنون پرس و جوIn very high strength concrete mixtures greater than 70 MPa the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength In lean concretes with a high water cement ratio the crushing strength of the aggregates is not so significantFINENESS MODULUS OF FINE AGGREGATE TxDOT Designation Tex 402 A Effective Date August 1 SCOPE 11 This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete 12 The values given in parentheses if provided are not standard and may not be exact
اکنون پرس و جوThis percentage is referred as ag g reg ate crushing value The crushing value of aggregate is restricted to 30 per cent for concrete used for roads and pavements and 45 per cent may be permitted fo r o ther structur The crushing value o f ag g reg ate is rather insensitive to the variation in strength of weaker aggregateAggregate is fed onto the high end of the top deck and the vibration causes the aggregate to jiggle down the screen until it either drops through a mesh aperture or falls off the end of a deck The aggregate is then sorted or screened according to the mesh sizes fitted from large aperture mesh at the top to small aperture mesh at the bottom
اکنون پرس و جوMar 11 32 The aggregate functions are then applied to each subset So I do the SUM and I am finished What is the partitioning and subsets for the MAX There is none When you learn SQL there is a concept of a “level of aggregation” for a table The way around it is with a window clause to force a function to aggregate at a different levelSep 12 32 Then crushed aggregates are then sieved through 236 mm sieve and weight of passing material W2 is expressed as percentage of the weight of the total sample W1 which is the aggregate crushing value Aggregate crushing value = W1/W2 100 A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be
