Question

What is the effect of temperature in mixing materials?​

Answer 1

Answer: The mixing temperature is the temperature of concrete at the exit of mixer after mixing which is computed by

(4.1)

where

—the mixing temperature of concrete

cs, cg, cc, cw—the specific heat of sand, gravel, cement, and water

qs, qg—the water content (%) of sand and gravel

Ws, Wg, Wc, Ww—the weight of sand, gravel, cement, and water in 1 m3 of concrete

Ts, Tg, Tc, Tw—the temperature of sand, gravel, cement, and water

Hc—the mechanical heat (kJ/m3) produced in the mixing process.
