Performance of Textile Mill Performance of Textile Mill Sludge as Fine AggregateSludge as Fine Aggregate

AIM

The aim of our project is to study the

strength of the concrete with replacement of

fine aggregate by Textile Mill SludgeTextile Mill Sludge.

INTRODUCTION• To increase the strength of concrete for replacement of cement for fly ash and sand

for textile mill sludge.

The textile industry is one of the oldest and largest sector in India. It generates

liquid waste from its different processes. After treatment of the textile waste water

in Effluent Treatment Plants, sludge is generated.

Government has allotted specific location for its disposal. Generated sludge mostly

disposed in landfill and dumping in the specified areas by Government.

The transportation and disposal process is very costly.

In this study, an attempt is made to find out the feasibility of using sludge textile

mill sludge as fine aggregates in M20 grade of concrete.

The replacement of fine aggregate with sludge in conventional concrete mix affects

workability and density of concrete.

M.V.Seshagiri rao, M.Janardhana and M.Swaroopa rani (2001)

Addition of fly ash has resulted in improvement in workability up to 40%

replacement in M20 concrete

Effects Of Mineral Admixture On Concrete

By : Sherzad Hakkari

In general concrete is a material that forms the basis of our modern life. It is the

most widely construction material used because it is easy to place and mold, low cost, its

ingredients is widely available and it has good compressive strength. Concrete is a

composite material consist of aggregates embedded in a hard matrix of cement filling the

space between the aggregate particles.

Environmental pollution has become an international problem which has

occupied the priority to be managed and controlled.

One of the important way of the control environmental pollution is waste management.

Literature Review:

Application of Sewage Dry Sludge as Fine Aggregate in Concrete

Jamshidi, A. , Mehrdadi, N. , Jamshidi, M.

In recent years, waste production has increased dramatically in developing

nations such as Iran. There are two methods for the disposal of solid waste (dry

sludge) including land filling and using the sludge as fertilizer.

Reuse of textile effluent treatment plant sludge in building materials

Cement concrete cube of standard size 150mm x 150mm x 150mm were

cast with 5, 10 and 15% of sludge. Three specimens were cast in each mix percentage

and the specimens were cured for 7, 14 and 28 days. The mix ratio adopted was

1:1.5:3. The average compressive strength of the concrete cubes

Selection of water & sand content for 20mm nominal size of aggregate zone III

Water content per m3 of concrete = 186kg

Percentage of total aggregate by absolute volume = 35%

Adjustment of values in water content & sand percentage for other conditions:

Therefore required sand content as percentage of total aggregate by absolute

Required water content =186 kg/m3

Determination of cement content

w/c ratio = 0.49

Water = 186

Cement = 186/0.49 =379.59 kg/m3 (min = 220 kg/m3)

The cement content is adequate for mild exposure condition

Determination of coarse and fine aggregate:

Assume entrapped air is 2%

0.98 = (186+(379.59/3.21)+(1/0.328)*(FA/2.67))*(1/1000)

Fine aggregate = 591.78 kg/m3

Coarse aggregate:

0.98 = (186+(379.59/3.21)+(1/1-0.328)*(CA/2.67))*(1/1000)

Coarse aggregate = 1206.69 kg/m3

Cement = 379.59 kg/m3

Fine aggregate = 591.78 kg/m3

Coarse aggregate = 1206.69 kg/m3

Mix ratio = 1:1.54:3.01

= 1 : 1.5 : 3

Materials calculation:

Three cubical specimens size = (150 mm x 150 mm x 150 mm)

= 0.15 x 0.15 x 0.15

= 3.375 x 10-3 m3

No of cubes = 3

= 3.375 x 10-3 x 3

= 0.010125 m3

MIXING

• Mix the concrete either by hand

HAND MIXING

(i)Mix the cement and fine aggregate on a water tight none-absorbent platform until

the mixture is thoroughly blended and is of uniform color

(ii)Add the coarse aggregate and mix with cement and fine aggregate until the

coarse aggregate is uniformly distributed throughout the batch

(iii)Add water and mix it until the concrete appears to be homogeneous and of the

desired consistency

SAMPLING

(i) Clean the mounds and apply oil

(ii) Fill the concrete in the molds in layers approximately 5cm thick

(iii) Compact each layer with not less than 35strokes per layer using a tamping rod

(steel bar 16mm diameter and 60cm long, bullet pointed at lower end)

(iv) Level the top surface and smoothen it with a trowel
