This is the Science of Concrete This site contains a vast amount of information that relates to the study of concrete and cement You will find information ranging from the mechanisms by which concrete hardens to various research techniques used to explore concrete and test its properti...
Concrete, usually Portland cement concrete (for its visual resemblance to Portland stone), is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently in the past a lime-based cement binder, such as lime putty, but sometimes with other hydraulic ....
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 the nanometre level of C-S-H, the principal product formed when cement is mixed with water, and the one mainly reponsible for its hardening...
• Goal is to reduce number of physical concrete tests, thus expediting R&D process • Based on NIST modeling effort over last 16 years – Brings together basic research on processing (cement chemistry), microstructure (multi-scale), and properties (physical and chemical) • Industrial consortium members: WR Grace, SIKA....
Too much water reduces concrete strength, while too little will make the concrete unworkable Concrete needs to be workable so that it may be consolidated and shaped into different forms (ie walls, domes, etc) Because concrete must be both strong and workable, a careful balance of the cement to water ratio is required when making concrete...
Cement, an ultra-fine grey powder, binds sand and rocks into a mass or matrix of concrete Cement is the key ingredient of concrete Making concrete is similar in principle to baking a cake: selected ingredients are mixed together, heated, and allowed to set...
A mixture with an excess of cement paste will be easy to place and will produce a smooth surface; however, the resulting concrete is not cost-effective and can more easily crack 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 aggregat...
Dec 19, 2017· 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 com....
The most common use for Portland cement is to make concrete Concrete is a composite material made of aggregate (gravel and sand), cement, and water As a construction material, concrete can be cast in almost any shape, and once it hardens, can be a structural (load bearing) element Portland cement may be grey or white Portland cement blends...

Cement is so fine that 1 pound of cement contains 150 billion grains The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process...
History of Cement • Although the method of making cement has been improved, the basic process has remained same • Cement production in Turkey was first started in Darıca Cement Factory in 1913 with a production capacity of 20,000 ton/year • Today the annual cement production in Turkey is more than 25...
The amount of cement paste used must be at minimum equal to the spaces in between the aggregate particles and a small amount more to make the concrete mixture relatively easy to move while pouring concrete and making the surface smooth This is known as “workability”...
I began learning cement chemistry working as a microscopist at Blue Circle's Research Department at Greenhithe in Kent in 1979 My geological background was invaluable as I started making laboratory mixes and firing then to make new rocks which I then examined under the microscope...
To get a more complete and integrated understanding of how cement is made, do have a look at the Understanding Cement book or ebook This easy-to-read and concise book also contains much more detail on concrete chemistry and deleterious processes in concrete compared with the website...
33 Raw materials for cement manufacture The first step in the manufacture of portland cement is to combine a variety of raw ingredients so that the resulting cement will have the desired chemical composition These ingredients are ground into small particles to make them more reactive, blended together, and then the resulting raw mix is fed ....
