Cement and Concrete Sectional Committee, CED 2

FOR WOR

This Indian Standard Part 1) was adopted by the Bureau Indian Standards, after the draft finalized by the

Cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council.

Chlorides in the concrete could be drawn from different sources like aggregates, mix water, admixtures and

cement and could lead to durability problems namely, corrosion

reinforcing steel in concrete if present in

sufficient quantity

Chlorides could be present in different degrees

binding in the concrete matrix and could

be determined as water soluble and as acid soluble chlorides. In some cases

corrosion

carbonated concrete,

the combined chlorides water soluble and acid soluble) will be let free in pore water and these chlorides are

bannful to concrete. To minimize the chances deterioration concrete due to harmful chlorides, the level

these chlorides has been limited in various design codes. Therefore, this standard has been formulated to provide

necessary guidance for determination

water soluble and acid soluble chlorides in concrete. This Part 1

the

standard covers volumetric method

test for determination chlorides in fresh mortar and concrete, and

Part

2

this standard covers the method

test for hardened mortar and concrete.

The composition

the committee responsible for the formulation

this standard is given in Annex A.

In

reporting the results

a test or analysis made in accordance with this standard, if the final value, observed

or calculated, is to be rounded off, it shall be done in accordance with IS 2 : 1960 Ru le s for rounding

numerical values

in one litre

of

distilled water in a volumetric flask.

Shake well and standardize by titrating with 0.02 N

silver nitrate solution using ferric alum solution as

an

indicator. Adjust the normality exactly to 0.02 N

4 8 Sodium Chloride NaCl), 0.02 N

Weigh 1.169 2 g

of sodium

chloride

dried

at

105 2e, dissolve in distilled water and make up to

1 000 ml in a volumetric flask.

4.2 Use

of

Filter Paper

In the methods prescribed

in.

this standard, relative

numbers of Whatman filter paper only have been

prescribed since these are commonly used. However,

any othersuitable brand of filter papers with equivalent

porosity may be used.

4.3 Procedure

4 3 rer Soluble Chloride

4.3.1.1 Weigh 1 000 5 g of fresh mortar or concrete

sample in a 2 litre capacity beaker and add 500 ml of

distilled w ate r c hl or ide free). S tir the mixture

vigorously for 15minutes. After allowing the mixture

to stand for 10to 15minutes for settling, decant about

200 ml of the supernatant solution into a clean dry

250 ml c apa city beaker. I mme dia tely, filter the

solution through Whatman filter paper No. 1 and

collect the filtrate.

4.3.1.2 Pipette 0 ml of filtrate in a 250 ml capacity

conical flask. Add 5 ml of 6 N nitric acid. Add a

known volume X), preferably 25 ml of 0.2 N silver

nitrate solution. Add 1 ml ferric alum and 5 ml

of

nitrobenzene. Shake vigorously to coagulate the

precipitate. Titrate the excess silver nitrate with

0.02 N a mm on iu m

thiocyanate

s ol ut io n unti l a

permanent faint reddish brown colour appears. Note

2

down the volume

Y of

ammonium thiocyanate used.

4 3 2 Acid Soluble Chloride

4.3.2.1 Weigh about 1 000 5 g of the fresh mortar

or concrete sample

in

a 2 litre capacity beaker and

add 50 ml

of

6 N nitric acid and 450 ml

of

distilled

water chloride free) after stirring for few minutes.

Stir the mixture vigorously for 15 minutes, After

allowing the mixture to stand for 10toIS minutes for

settling, decant about 200 ml of the supernatant

s ol ution into a clean dry 250 ml capacity beaker.

. Immediately, filter the solution through Whatman

filter paper No. 1 and collect the filtrate.

4.3.2.2 Pipette ml of filtrate

in

a 250 ml capacity

conical flask. Add 5 ml

of6

N nitric acid. Add a known

volume

X),

preferably 25 ml

of

standard silver nitrate

solution.

Add 1 ml

ferric alum and

5 ml

of

nitrobenzene. Shake vigorously to coagulate the

precipitate. Titrate the excess silver nitrate with 0.02 N

ammonium thiocyanate solution until a permanent

faint reddish brown colour appears. Note down the

volume

Y)

of ammonium thiocyanate used.

4.4 Calculation

Calculate the percentage

of

chloride acid soluble/

watersoluble)by massofmortaror concrete as follows:

Chloride, percent

=

0.0007 1

Y ,

where

X

volume

of

silver nitrate added, in ml; and

Y volume of 0.02 N ammonium thiocyanate

consumed.

NOTE

-Interference

of silverchloridepanicles whichare gen-

erated

ill situ

in titration

by

reacting with thiocyanate can be

avoided by the addition of nitrobenzene which formsa film on

silverchlorideparticles.
