The hydration products of slag cement are generally found to be more gel-like (less crystalline) than the products of hydration of portland cement; thus, they reduce the permeability of the cement paste (ACI 233R). Slags are used as a replacement of portland cement in amounts typically between 25 and 70% of the total mass of cementitious material.
Paste serves as the binder that holds aggregates in place and gives concrete its engineering properties, making it a reliable and versatile construction material. But even this dynamic duo of cement and water are better off as a trio, particularly in terms of cement, water and supplementary cementitious materials.
CHAPTER 1 COMPONENTS OF CONCRETE Concrete is made up of two components, aggregates and paste.
