The document discusses the relationship between process and quality in cement production. It notes that quality is dependent on maintaining consistent processes. Variations in raw materials, mining, blending, and other processes can negatively impact quality. Proper quality control aims to minimize these variations and ensure the final product meets specifications. The key is integrating quality control throughout the entire production process from start to finish.

260 MTPA capacity, with greater growth prospects
and promising future ahead. Cement industry has
been an excellent example of a fast growing sector
showing consistent and steady reduction in its
energy consumption. This has largely been
possible by steady and continuous improvement

ENERGY MODELING OF THE PYROPROCESSING OF CLINKER IN A ROTARY CEMENT KILNISA Interchange
This paper highlights the efforts taken by the author in developing an Energy Model for the pyro-processing of Clinker production in a dry-process rotary cement kiln. In this paper this Energy Model is applied to a state of the art cement plant in a Far East Asian country. However this Energy Model is also applicable to all the modern dry process cement kilns. This model is based on actual field input data and site observations.

The Effect of Rise Husk Ash on Strength and Permeability of ConcreteAkshay D Nicator
HA, produced after burning of Rice husks (RH) has high reactivity and pozzolanic property. Indian Standard code of practice for plain and reinforced concrete, IS 456- 2000, recommends use of RHA in concrete but does not specify quantities.
Experimental Study of Sulphate Attack on Neutralized Red MudIJRES Journal
Concrete exposed to sulfate solutions can be attacked and suffer deterioration by expansion. The deterioration of reinforced concrete by sulfate attack causes the reinforcing steel to be exposed to the action of aggressive agents starting the corrosion of the reinforcement. It is known that the concrete resistance to sulfates can be significantly improved producing a dense waterproof concrete. Both the physical resistance of concrete to the penetration and capillary-induced migration of aggressive agents and the chemical resistance of the concrete to the deleterious reactions described above are important attributes of sulfate resisting concrete. Thus factors influencing the permeability and surface porosity of the concrete and the chemical resistance of cement are prime performance parameters of concrete exposed to sulphate attack. In this project physical resistance of concrete is traditionally achieved by specifying mix design parameters such as maximum water–cement ratio and minimum cement content, while the chemical resistance is by the use of sulphate resisting cement.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

2. Why we maintain quality ?
It is need of the customer
Customer is the king .He sees us in quality price ratio
To day mason decides the quality but tomorrow engineer
will decide the quality in our country ( house construction
, etc)
What will happen to us ?
3. Customer is the king. He is a better business man than you.
Tomorrow’s market is competitive with quality/ price ratio.
Customer creates the customers.
Bon’t brand the quality alone , brand your service too.

Ks ; 1 d : + 4 Mpa / %
: 3 d : + 4 Mpa / %
: 7 d : - 2 Mpa / %
: 28 d : - 10 Mpa / %

optimum
Blaine : 1 d : + 0.04 Mpa / (m2/ kg)
3- 28 d : + 0.08 Mpa / (m2/ kg)
78. One day strength is contributed mainly by
C3A , Soluble alkalies, and C3S
3 day is contributed mainly by C3S
7 days strength is contributed by mainly
C3S
28 days strength is mainly contributed by
C2S
Apart from the above cement strength is enhanced by
higher fineness of cement
Less C3S crystal size achieved by rapid burning
and quenching the clinker in cooler
Higher fineness of rawmeal also reduces the
crystal size of clinker minerals , ie ., C3S & C2S which
enhances the hydraulic reactivity
Cement strength – influencing parameters
79. Wk , prehydration of clinker
Prehydration of clinker minerals can occur
1. As a result of incorrect internal water cooling in cement mill
2. when storing too hot cement in a silo
3. When clinker and especially cement is exposed to humidity
Please note:
If clinker has more soluble alkalis and sulfates it is highly
hygroscopic especially when pet coke is fired.
In cement silos they form Syngenite , K2SO4.2 CaSO4. H2O which
forms lumps and block the cement silos. Hence venting is must
to evacuate moisture and silo cleaning.
cements having soluble alkalis and sulfates preferably packed in
paper bags to avoid depletion of strength.
80. Thumb rule formulae for prediction of strength
FLS predicted the formula for cement ground to 300 kgs/ m2
With 4 % gypsum
strength,
d28 = 52 - 10.( Ks) + 0.15.(C3S)
The content of soluble alkalis Ks is dependent on the total alkali
content and SO3 content in clinker.
As per Knofel it is
F 28 = (3*C3S)+ (2*C2S) + C3A – C4AF N / mm2
Strength prediction
for 3 d = 97 + 35.8 Ma + 38.1K2SO4 + 28.7 Ms – 1.3 C3S Kg/ cm2
7 d = 300 + 13.4 Ms + 2.8 C2S + 56.1 Ma – 15.4 K2SO4 + 15.5 Na2O
28 d = 490 – 55.3 K2SO4 + 1.3 C3S (or)
= 490 – 86 K2O + 2 C3S – 26 Na2O
81. Influence of fineness on cement strength
For cements with the same specific surface the increase of the uniformity
factor results in increase of strength of all ages.
1. The specific surface , the percentage of fractions 3- 32 mm and the
uniformity factor n really influences the development of cement strength.
The influence of 3 - 32 mm fraction and the uniformity factor is higher in
cement with higher in specific surface ( > 3400 cm2/ g)
2. The fractions with particle size less than 3 mm contributes only to early
strength while the fraction with particle size more than 24 mm influences
strength development significantly.
3. While the fractions 3 – 16 mm and 16 – 32 mm seems to be more
significant factor for specific surface 3500 – 4000 cm2/ g) . This is
relevant only if the granulometric distribution is continuous and steep.
4. The optimistic granulometric distribution of a cement is a continuous
and steep ( with high uniformity factor) distribution with a high (65 %)
content in 3 – 32 mm fraction and specifically in 16 - 24 mm fraction and
low content of fine particles ( < 3 mm , 10 % ) and specific surface of
2500 – 3000 cm2/ g according to Blaine.( high efficiency separator and
grinding media distribution plays significantly here)
82. Properties of cement minerals

92. Problems and solutions
1. Grinding problems
a) False set lower cement mill temperature
add less gypsum
add part anhydrite
b) reduced strength high mill temperature
less water cooling
correct water cooling
2. Silo storage
a) False set short storage time
cooling of cement < 70 deg c
b) reduced strength increase gypsum dehydration in
mill
c) lump formation and add less gypsum, use partly
silo blockage (syngenite anhydrate , decrease K2O content
formation, K2SO4.2CaSO4.H2O to avoid the formation of Syngenite
Problems solutions
93. 3 ) Bag storage
a. reduced strength short storage time
b. lump formation add TEA during grinding
(tri ethanal amine)
add hydrophobic agents
c. crust formation plastic coated bags
d. abnormal setting plastic covering pallets
