====Formulae====
=====Coarse Aggregate Calculations=====
======Apparent Particle Density======
'''ρA = (M1 x ρW) / (M1 - (W1 - W2))''' 

where, 
ρA= Apparent Particle Density (t/m3) 
M1 = Mass of dry aggregate in air (g) 
W1 = Weight of basket and aggregate under water (g) 
W2 = Weight of basket under water (g) 
ρW = Density of water at test temperature (from Table 1) 

======Particle Density on Dry Basis======
'''ρD = (M1 x ρW) / (M2 - (W1 - W2))''' 

where, 
ρD= Particle Density on Dry Basis (t/m3) 
M1 = Mass of dry aggregate in air (g) 
M2 = Mass of SSD aggregate in air (g) 
W1 = Weight of basket and aggregate under water (g) 
W2 = Weight of basket under water (g) 
ρW = Density of water at test temperature (from Table 1) 

======Particle Density on Surface-Saturated Dry Basis======
'''ρS = (M2 x ρW) / (M2 - (W1 - W2))''' 

where, 
ρS= Particle Density on SSD Basis (t/m3) 
M2 = Mass of SSD aggregate in air (g) 
W1 = Weight of basket and aggregate under water (g) 
W2 = Weight of basket under water (g) 
ρW = Density of water at test temperature (from Table 1) 

======Water Absorption (%)======
'''WA = (M2 - M1) x 100 / M1''' 

where, 
WA = Water Absorption (%) 
M1 = Mass of dry aggregate in air (g) 
M2 = Mass of SSD aggregate in air (g) 

=====Weighted Calculations=====
Weighted calculations are not available on this screen. To get the weighted results you need to add the screen '''Particle Density - Coarse [As 1141.6.1] '''to the sample.
