Cement Flashcards
The most common form of Calcium Carbonate (CaCO3) which can vary from soft marls and chalk to the hardest of marbles.
Limestone
Plays a vital role in limestone pre-homogenization, it stabilizes the cement kiln condition
and ensures clinker quality.
Stacker and reclaimer
Besides extending the residence time of materials in the equipment, the ________ can also improve the fuel combustion rate so the equipment’s temperature can be
maintained in a specific range during cement production.
Precalciner
This involves removing excess moisture as it can result in various issues during the
calcination process.
Combustion
It provides heat energy required to sustain the calcination reaction
Combustion
It is characterized by a very rapid rate of development of strength and superior
resistance to seawater
Calcium aluminate
Heat is provided by burning oil, gas, or pulverized coal, using preheated air from cooling.
Dry process
Cement accounts for ____of CO2 emissions worldwide
6-9%
A 100% Filipino-owned cement firm that was recently established in January 2018.
Big Boss Cement Inc.
The significant industry participant that made it through the difficult time when a suddenboom in cement companies pushed several businesses to collapse, leading to an
excess of cement.
Bacnotan Plant
John Smeaton discovered that lime’s hydraulicity is directly proportional to what?
limestone’s clay content
Produced modern-day cement when he fired chalk and clay at 1400-1500°C which led to
the mixture clinkering.
Isaac Johnson
Calcareous materials should contain less than how many percent of MgO?
3.3%
used in large quantities for the fabrication of corrosionproof linings for chemical
equipment
Special or corrosion-resisting cements
are the usual products for general construction
Portland Cement
