Abstract:
These presentations include an introduction and overview of the revised documents E3, “Cementitious Materials for Concrete,” and E4, “Chemical Admixtures for Concrete,” developed by Education Committee E701, Materials for Concrete Construction. E3 discusses portland, blended, and other hydraulic cements, along with supplementary cementitious materials such as slag cement, fly ash, and silica fume. E4 covers air‑entraining admixtures, water-reducing and set‑controlling admixtures, as well as specialty admixtures for various specific applications. Since these documents are intended for users and students, the information is presented in a more practical and instructive format than their technical committee counterparts.
