Calculations Flashcards
1
Q
ACI and Moisture correction
A
Water: 62.4 lb/ft3
Bulk =62.4x specific gravity
2
Q
Finess modulus
A
Just looking for the total then cumulative
3
Q
Capillary porosity
A
CP=(Vi_water-.5(Vp)) / total volume
Vf_cement= 2(%hydrated)(Vi_cenent)
4
Q
Water cement ratio using capillary porosity
A
V_water + V_cement= V_total
V_cement_hydr = 2(%hydrated)(V_cem_i
5
Q
Ultimate strength
A
E_secant= (.4 fâ) / max strain
6
Q
Void content
A
Void% =
SG_agg62.4-density_agg) / (SG_agg62.4
7
Q
Free moisture
A
W_ssd= W_dry(1+AC)
FM=(W_actual-W_ssd)/(W_ssd)
