Module 4.1 - Chemical Equations - UW-Madison Chemistry
Chemistry is the study of chemical reactions, processes in which reactants are converted to products. Chemical equations are a shorthand way of representing these reactions. They are always written: Reactant(s) Product(s) The arrow in this shorthand notation can be thought of as meaning "forms" or "yields".

Lecture 2. Portland cement
The proportions of the chemical compounds of cement vary in the various Portland cements. Table 2-2 presents the composition and percentage of found compounds for Portland cement.
Ultra-High Performance Concrete - Portland Cement Association
Ultra-High Performance Concrete (UHPC), is also known as reactive powder concrete (RPC). The material is typically formulated by combining portland cement, supplementary cementitious materials, reactive powders, limestone and or quartz flour, fine sand, high-range water reducers, and water.

Concrete Production - an overview
Nonetheless, it is recognised that most of the embodied energy of concrete is used in the cement production for crushing, grinding, rotating the kiln, etc. Annually, at a European cement plant, the power consumption and the required thermal energy were, on average, 117 kW h/t of cement and 3.75 MJ/t of clinker, respectively (WBCSD/CSI, 2013).

Hydration Products of Cement
Aug 14, 2017 · During the Hydration of the cement, the major Bouges compounds C 3 S and C 2 S are responsible for the setting and the hardening of the cement. In the presence of water, the silicates and aluminates form products of hydration that will result in a hard mass over a period of time. This hard mass is called as the Hydrated Cement Paste (HCP).
How Concrete is Made - Portland Cement Association
In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
