Fly Ash Determination In The Supplied Portland

Pozzolana Cement

There is no direct method for the determination of Fly Ash content in the PPC. However,

based on the past test results of insoluble Residue in the PPC, Fly Ash content in the suppliedPPC may be obtained.

REAGETS

1. Hydrochloric acid !p "t 1.1# $conformin" to %! & '#()1*+#

'. -ilute Hydrochloric acid with distilled water 1&** $by volume

. '/ !odium Carbonate !olution.

DETERMINATION OF INSO!"E RESID!E

The sample of the PPC shall be moisture free and ta0en as per reuirements of %! & (()

1*##. The representative sample of the cement selected as above shall be thorou"hly mi2ed before usin".

Ta0e one "ram of the above PPC sample add '( ml of cold water and while the mi2ture is

stirred vi"orously add ( ml of hydrochloric acid, if necessary, head the solution and "rind the

material with flattened end of a "lass rod until it is evident that the decomposition of the

cement is complete. -ilute the solution to (3 ml and di"est for 1( minutes at a temperature

4ust below boilin". Filter and wash the residue thorou"hly with hot water. The filter paper

with the residue shall be proceeded for further test.

-i"est the filter paper containin" the residue in 3 ml of hot water and 3 ml of '/ sodiumcarbonate solution maintainin" constant volume, the solution bein" held at 4ust below the

boilin" point for 13 minutes. Filter and wash with dilute hydrochloric acid $1&** and finally

with hot water till the residue is free from chloride. %"nite the residue in a tarred crucible at

*33 to 13333C, cool in a desicator and wei"ht

From the fi"ure the insoluble residue obtained from the above test, Fly Ash content in the

supplied PPC may be obtained. Read references to conduct e2periments and find conclusions.

INTROD!CTION

water reducers and capable of reducin" water content by about 3. The !uperplastici@ers

are broadly classified into four "roups& sulfonated melamine formaldehyde condensate

$!8F, sulphonated naphthalene formaldehyde condensate $!/F, modified li"nosulphonate

$8B! and others includin" sulphonic acid ester, polyacrylates, polystryrene sulphonates, etc.

The benefits obtained by !uperplastici@ers in the reduction of water in the concrete mi2es are

best illustrated by the followin" e2amples.

MA1ING CONCRETE%

Nust mi2 cement, a""re"ates and water, cast this mi2 in a mould, open the mould ne2t day. A

uniform hard mass will be found, which is 0nown as concrete, any body can ma0e it. The

simplecity in ma0in" concrete ma0e this material to be loo0 li0e very simple in its

production, yet it as not so simple. -ue to i"norance about concrete no other buildin"

materials ever mis)used as concrete in the construction. %n %ndia concrete is bein" used in theconstruction since the last +3 years. et 53 of the builders have no proper understandin" of

this materials. ?o to any construction site $e2cept bi" construction sites you will find that

sand and a""re"ates are bein" ta0en in iron tasla or cane bas0ets to char"e the mi2er without

the consideration of site a""re"ates actual "rindin"s, moisture content and bul0in" of sand.

The water is poured in the mi2er without any measured uantity. %t could be well ima"ine

what sort of concrete structure will be made with the concrete bein" produced in this crude

method.

8ost of the contractors, builders, masons etc. still follow 1&'&= or 1&1.(& mi2es they are not

aware of -esi"n 8i2es and Concrete Admi2tures. This paper described how -esi"n 8i2es

can be converted into volume with 1 :a" Cement, ' :o2es of sand and = :o2es ofA""re"ate. The site practical problem is the dispersion of water and liuid admi2tures into

the mi2er. For this the site should fabricate a plastic circular "raduated measurin" container

of 3 lit capacity with a tap fitted at its bottom. This container is to be fitted on top of the

mi2er. From this container water and liuid admi2tures can conveniently poured direct into

the mi2er in a measured uantity.

?ood uality concrete starts with the uality of materials, cost effective desi"ns is actually a

by)product of selectin" the best uality material and "ood construction practices. Followin"

are 13 Thin"s to remember durin" Concrete 8i2 -esi"n and Concrete Trials.

1. AC% and other standards only serves as a "uide, initial desi"ns must be confirmed by

laboratory trial and plant trial, ad4ustments on the desi"n shall be done durin" trial mi2es.%nitial desi"n Xon paperY is never the final desi"n.

'. Always carry out trial mi2es usin" the materials for actual use.

. Carry out ' or desi"n variations for every desi"n tar"et.

=. Consider always the factor of safety, $1.1'(, 1.', 1.'(, 1. K tar"et stren"th

(. :efore proceedin" to plant trials, always confirm the source of materials to be the same as

the one used in the laboratory trials.

#. Chec0 calibration of batchin" plant.

+. Carry out full tests of fresh concrete at the batchin" plant, specially the air content and

yield which is very important in commercial batchin" plants.

5. Correct uality control procedures at the plant will prevent future concrete problems.

*. Follow admi2ture recommendations from your supplier

13. Chec0 and verify stren"th development, most critical sta"e is the and + days stren"th.
