0引言化学外加剂技术的广泛使用,极大地提高了水泥混凝土的工作性能、力学性能及耐久性能,拓展了水泥混凝土的应用范围和领域[1-2]。随着混凝土外加剂性能的不断提高,种类的不断增多,外加剂与水泥的相容性问题成为工程界和学术界广泛关注的热点问题。目前,减水剂使用最为普遍,其与水泥间相容性问题也能够比较快速直观地反映出来,因而在实际工程中减水剂与水泥之间的相容性问题表现得尤为突出。
0 Introduction The extensive use of chemical admixture technology has greatly improved the performance of cement concrete performance, mechanical properties and durability, and expand the scope and application of cement concrete [1-2]. With the continuous improvement of the performance of concrete admixtures, increasing types, compatibility of additives and cement has become a hot issue of widespread concern in engineering and academia. Currently, the use of superplasticizer is the most common, and the compatibility between cement and cement can also be relatively quickly and intuitively reflected. Therefore, the compatibility between water-reducer and cement is particularly prominent in practical engineering.
