Testing Methods for Determination of Water-to-Cement Ratio of Fresh Concrete - A Short Review
摘要
Abstract
Water-to-cement ratio is a critical factor determining the quality and durability of concrete. It is thus of great significance to precisely determinate the water-to-cement ratio of fresh concrete during construction. This review summarized some published testing methods for the determination of water-to-cement ratio as to provide a scientific base for the selection and further development of new methods. Among all these methods, microwave method is the simplest and the most practical one. However, it determines only the water content of fresh concrete, and cement content has to be determined in order to calculate water-to-cement ratio. Electrical resis- tivity method has a high accuracy, but it has to establish relationship between water-to-cement ratio and electrical resistivity. Other methods have lack of either accuracy or practicability at the construction site. None of those has gained widespread acceptance for use in the field. Besides, the methods for the determination of cement content in concrete were also discussed.关键词
