Aggregate and Water Heating

FREE MOISTURE AND WATER ABSORPTION IN AGGREGATE FOR CONCRETE

5.3 Place the wet aggregate in the pycnometer and fill with water at the same temperature as used to calibrate the pycnometer. 5.4 Remove all entrapped air from the pycnometer using one of the procedures outlined in Tex-403-A. 5.4.1 For fine aggregate, use Sections 6.2.17–6.2.21. 5.4.2 For coarse aggregate, use Sections 6.3.11–6.3.12.

Step 1 - find the energy required to heat up 12 000 kg of water from 8°C to 60°C in 2 hours by using Equation 2.6.1: Steam is supplied to the control valve at 2.6 bar g. In order to calculate the mean steam flowrate, it is necessary to determine the total enthalpy in the steam (hg) at this pressure. It can be seen from Table 2.11.1 (an ...
