INFLUENCE OF DIFFERENT KINDS OF CEMENT ON EARLY SHRINKAGE OF CONCRETE

摘要

The problems of concrete shrinkage have been debated by a number of authors, including those specialising in concrete chemistry, to civil engineers. The development of concrete technologies, introducing chemical admixtures and mineral additives and high resistance concretes has contributed to creating a wider perspective on shrinkage in recent years and charting a new area of research. The authors of this publication belong to a group of researchers focusing their work on these issues. This article is the result of their literature curves, research work and conclusions drawn. The advances in recent research resulted in taking into consideration the following stages: initial shrinkage comprising: swelling, chemical (contraction), and plastic shrinkage, followed by expansion and then a second shrinkage (during drying).
