Credit: Mark Fulton -------------------------------------------------- Portland cement clinker - Overview Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch. For more information see the following pages, or better still, the Understanding Cement book - links at the bottom of this page. Portland cement clinker contains four principal minerals: Alite: approximately tricalcium silicate (typically about 65% of the total) Belite: approximately dicalcium silicate (typically about 15% of the total) Aluminate: very approximately tricalcium aluminate (typically about 7% of the total) Ferrite: very approximately tetracalcium aluminoferrite (typically about 8% of the total) The balance is made up of alkali sulfates and minor impurities. The typical mineral contents shown are subject to wide variation. ---------------------------------------------------- LOCOMOTIVE GENERAL PARTICULARS Model RL30SCC-3 Power 2461kW gross (3300hp) Power 2240kW traction (3000hp) Tractioneffort - continuous 300kN@18km/h Braking effort 210kN Total mass 108tonnes Axleload 18tonnes Wheel arrangement Co-Co Maximum speed90km/h Wheel diameter 914mm(36“) Fuel capacity 7000litres Engine EMD16-645E3B. ------------------------------------------ Copyright © 2019 Zimbabwe Railways.
