Cement chemistry can affect the dispersion efficiency of superplasticizers in various ways. One of these is through the ionic composition of the aqueous phase and in particular through the amount of soluble sulfates. The milestone paper on this subject comes from Yamada and Hanehara (2001).As explained in Section 7.3.1 on the reversibility of polymer adsorption, they made alternative additions

The most authoritative book there is for novice and specialist chemists and material scientists in the field of cement chemistry. H.F.W. Taylor, the pope in the field of (applied) cement crystallography, writes clearly and concisely on a topic he has seen develop over the last half century
A few basic chemistry notes ... Some very basic chemistry will help a lot with understanding how cement is made and how it works. If you missed out on chemistry at school, or it just seems a long time ago, the following short notes might be useful. Basic Chemistry 1: Chemical symbols
cement faces its toughest challenge under ground—in oil and gas wells where envi- ronmental conditions are far more severe than any encountered on the earth's surface. This artic e outlines the chemistry of port- land cement, the variety used to cement casings in wells and provide zona isolation, and explains how additives faci itate cement
But few people actually understand what gives concrete its strength, resistance, and utility. The aim of this course is to offer basic cement chemistry to practitioners, as well as new students in the fields of chemistry and engineering. You will learn how cement is made and hydrated, as well as the environmental and economical benefits it offers
Portland cement's chemistry comes to life in the presence of water. Cement and water form a paste that coats each particle of stone and sand—the aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete
Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement
Cement Chemistry. Cement is chiefly of two kinds based on the way it is set and hardened: hydraulic cement, which hardens due to the addition of water, and non-hydraulic cement, which is hardened by carbonation with the carbon present in the air, so it cannot be used underwater
Concrete is not as likely to rot, corrode, or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the work-site which reduces costs. Concrete is a non-combustible material which makes it fire-safe and able withstand high temperatures

Cement chemistry, 2nd edition. Authors: H.F.W. Taylor. Published: 1997. | View Chapters. H F W Taylor was for many years Professor of Inorganic Chemistry at he University of Aberdeen, Scotland. Since 1948, his main research interest has been the chemistry of cement. His early work laid the foundations of our understanding of the structure at
Chemistry of cement . The cement clinker is produced by igniting a mixture of raw materials, one of which is composed mainly of cal. carbonate and the other of alumino-silicates and oxides of Al and Fe. The following complex mineralogical compounds constitute the cement clinker
Clinker: Cement chemistry notation. Cement chemists use a form of notation which, at first sight - and maybe second or third sight - may seem a little odd. Oxides are referred to by their first letter: 'C' represents CaO; 'M' is MgO and so on, for all the oxides likely to be encountered in cementitious systems, as shown below. Normal chemists
