Brajadulal Chattopadhyay, in Smart Nanoconcretes and Cement-Based Materials, 2020. 1.3 Portland cement. Portland cement is the basic ingredient of concrete, mortar and plaster which consists of a mixture of oxides of calcium, silicon and aluminum. Portland cement and similar materials are made by heating (about 1350–1400°C) limestone (a source of calcium) with clay and then grinding this ...

Determination of amorphous phase levels in Portland

I. INTRODUCTION. Portland cement, the most commonly used building material, is obtained from ground cement clinker which is manufactured by burning or calcining a limestone and clay mixture or chemically equivalent materials in a kiln at high temperature (Taylor, Reference Taylor 1990, p. 1).Portland cement clinker consists of four major phases: alite (C 3 S), belite (C 2 S), aluminate (C 3

Pros Cons of Ordinary Portland Cement (OPC) Over ...

Both Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC) are used in constructions. However, some pros and cons of OPC over PPC are listed below. Pros of OPC over PPC: 01. Initial setting time of OPC is faster than PPC so it is recommended in projects where props are to be removed early. 02. It is easy to handle as compared to PPC. 03. Its initial strength higher than PPC.
