Title: New Generation Hyperplasticisers For The New Millennium
Appears on pages(s):
Abstract:The use of high performance concrete has significantly increased over the past decade in Australia. Coupled with this increase is the utilisation of specialty admixtures such as superplasticisers in concrete. Recently, a new generation of superplasticisers based on modified polycarboxylic ethers (PCE) polymer technology has been introduced in Australia. These polymers possess unique chemistries that act as powerful cement dispersants as well as providing exceptional workability retention without retardation and segregation. The mode of action of PCE superplasticisers can be described as being of a triple mechanism. This improves both the dispersion and slump retention of the concrete even with low w/c ratios. This paper will discuss the history, mechanism of action and present some laboratory performance data and applications of PCE superplasticisers in the field.
