This document discusses Portland cement and the cement manufacturing process. It begins with an overview of what cement is and how it is used to make concrete. It then describes the industrial process for manufacturing cement, involving grinding raw materials like limestone and clay at high temperatures in a kiln to form clinker, which is then pulverized with gypsum to become Portland cement powder. The document also provides a brief history of cement development and explains how cement kilns can beneficially reuse solid and hazardous wastes as a source of energy and raw material replacement due to the kilns' high temperatures and long retention times.

Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic crystals or a gel-like material with a high surface area. Because of their hydrating properties, constructional cements, which will even set and harden under water, are often called hydraulic cements. The most important of these is portland cement.

Cement refers to the commodities that are produced by burning mixtures of limestone and other
minerals or additives at high temperature in a rotary kiln, followed by cooling, finish mixing, and
grinding. This is the manner in which the vast majority of commercially-important cementations
materials are produced in the United States. Cements are used to chemically bind different
materials together. The most commonly produced cement type is "Portland" cement, though
other standard cement types are also produced on a limited basis.
Cement plants produced 99.8 million metric tons of cement. Worldwide production accounted
for about 2.5 billion metric tons. As with most large manufacturing industries, by-product
materials are generated. These industrial by-product and waste materials must be managed
responsibly to insure a clean and safe environment.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Cement manufacturing process
1. 1.What is cement ?
2.History.
3.Overveiw of Cement
Manufacturing process.
4.Overveiw of Kiln process.
5.Why burn wastes ?
2. Portland Cement
. A hydraulic cement made by finely
powderising the clinker produced by
calcining to incipient fusion a
mixture of argillaceous and
calcareous materials.
.Portland cement is a powder that is the
active ingredient in concrete.
3. Concrete
It is prepared by:-
. Shovel powder…………Portland Cement
. Shovels sand…………Mineral Aggregate
. Shovels Rock………. Mineral Aggregate
. Add water & mix.
. It is ready to mend .
5. Concrete
• Mixture of ingredients into a paste &
triggers a chemical reaction – hydration.
• Reaction forms a gel which coats & fills
spaces between the stone/sand;
• Hardens into a solid mass that
gets stronger & stronger.
6. Concrete
• The world’s most widely used building
material.
• Global production is 5 billion cubic yards
per year (using approximately 1.25 billion
tons of cement).
7. Concrete owes its strength and
durability to one essential ingredient -
Portland Cement.
8. Portland Cement
• Limestone + Shale/Clay + Heat = Clinker +
CKD + Exit Gas.
• Material Temperatures Exceed 2700 degrees F
• Pulverized Clinker + Gypsum = Portland
Cement.
• Cement is powder so fine that one pound
contains 150 billion grains.
9. Portland Cement (cont’d)
• Basic Chemical Components of Portland Cement:
– Calcium (Ca)
– Silicon (Si)
– Aluminum (Al)
– Iron (Fe)
• Typical Raw Materials:
– Limestone (CaCO3)
– Sand (SiO2)
– Shale, Clay (SiO2, Al2O3, Fe2O3)
– Iron Ore/Mill Scale (Fe2O3)
13. History of Portland Cement
• First cements produced by early Greeks and
Romans from volcanic ash mixed with slaked lime.
• This art was lost during the Middle Ages.
• Portland cement developed in England by
bricklayer Joseph Aspdin in early 1800’s.
• Called “Portland” because concrete made with it
resembled natural stone from the Isle of Portland.
14. History of Portland Cement
• First rotary kiln designed to produce Portland
cement patented in 1885 by Frederick Ransome.
• First economical U.S. kilns developed by Atlas
Cement Company in 1895.
• Thomas A. Edison first developed long kilns (150
feet compared to 60 to 80 feet).
15. Types of Cement Processes
• Wet Process.
• Dry Process - 74% of cement produced.
• Preheater/Precalciner Process.
16. Evolution of the cement
Process
• Wet process easiest to control chemistry & better
for moist raw materials.
• Wet process high fuel requirements - fuel needed
to evaporate 30+% slurry water.
• Dry process kilns less fuel requirements
• Preheater/Precalciner further enhance fuel
efficiency & allow for high production rates.
