Title: INFLUENCE OF CEMENT FINENESS AND LIMESTONE CONTENT ON STRENGTH DEVELOPMENT AND DRYING SHRINKAGE OF PORTLAND LIMESTONE CEMENT
Author(s): Nguyen Nhu Quy
Appears on pages(s): 38-44
Keywords: Portland Limestone Cement cements fineness, cement strength development, and cement mortar shrinkage.
Abstract:The production of Limestone Portland Cement was proved to be an effective approach to limit the carbon dioxide emission associated with cement clinker firing promoting sustainability development. The addition of limestone to some extent reduces the cement strength so the cement manufacturers try to increase as high as possible the cement fineness to accommodate more limestone content while maintaining its target strength at desired level. Some problems may arise in the concrete made from such a kind of cement, namely the threat of concrete cracks due to shrinkage when it is made from cement having too fine and too fast in rate of hardening. There are not many research publications available dealing with the strength development and shrinkage of the Portland Limestone Cement with varying fineness and different limestone content. This paper reports the influence of the Portland Limestone Cement fineness and limestone content on its strength development and shrinkage. Hence these research results could help to set the limits of Portland Limestone Cement fineness for corresponding limestone content to minimize the threat of the concrete cracks which may harm its durability in use.
