=====Coarse Aggregate Calculations=====
======Apparent Particle Density======
'''&rho;<sub>A</sub> = (M<sub>1</sub> x &rho;<sub>W</sub>) / (M<sub>1</sub> - (W<sub>1</sub> - W<sub>2</sub>))'''<br>

where, <br>
&rho;<sub>A</sub>= Apparent Particle Density (t/m<sup>3</sup>) <br>
M<sub>1</sub> = Mass of dry aggregate in air (g) <br>
W<sub>1</sub> = Weight of basket and aggregate under water (g) <br>
W<sub>2</sub> = Weight of basket under water (g) <br>
&rho;<sub>W</sub> = Density of water at test temperature (from Table 1)<br>

======Particle Density on Dry Basis======
'''&rho;<sub>D</sub> = (M<sub>1</sub> x &rho;<sub>W</sub>) / (M<sub>2</sub> - (W<sub>1</sub> - W<sub>2</sub>))'''<br>

where, <br>
&rho;<sub>D</sub>= Particle Density on Dry Basis (t/m<sup>3</sup>) <br>
M<sub>1</sub> = Mass of dry aggregate in air (g) <br>
M<sub>2</sub> = Mass of SSD aggregate in air (g) <br>
W<sub>1</sub> = Weight of basket and aggregate under water (g) <br>
W<sub>2</sub> = Weight of basket under water (g) <br>
&rho;<sub>W</sub> = Density of water at test temperature (from Table 1)<br>

======Particle Density on Surface-Saturated Dry Basis======
'''&rho;<sub>S</sub> = (M<sub>2</sub> x &rho;<sub>W</sub>) / (M<sub>2</sub> - (W<sub>1</sub> - W<sub>2</sub>))'''<br>

where, <br>
&rho;<sub>S</sub>= Particle Density on SSD Basis (t/m<sup>3</sup>) <br>
M<sub>2</sub> = Mass of SSD aggregate in air (g) <br>
W<sub>1</sub> = Weight of basket and aggregate under water (g) <br>
W<sub>2</sub> = Weight of basket under water (g) <br>
&rho;<sub>W</sub> = Density of water at test temperature (from Table 1)<br>

======Water Absorption (%)======
'''WA = (M<sub>2</sub> - M<sub>1</sub>) x 100 / M<sub>1</sub>'''<br>

where, <br>
WA = Water Absorption (%)<br>
M<sub>1</sub> = Mass of dry aggregate in air (g) <br>
M<sub>2</sub> = Mass of SSD aggregate in air (g) <br>

=====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.<br>
