l.INTRODUCTION

ln recent time, considerable. amount of construction activities are taking place in

Bangladesh. Aggregates are the major construction materials of these construction

projects. ln the forthcoming years the demand of stone aggregate is expected to increase

significantly both in public and private sectors. ln addition to the hectic construction of

residential and office building in the country, quite a few major construction projects

(especially, bridge, barrage, runways and highways) are already in the pipeline or in the

planning process. During the construction of the Bangabandhu bridge the shortage of

suitable aggregate supply was a major concem to the authorities. Ultimately, the bulk

portion of aggregates used in the river training work of Jamuna bridge was imported from

Bhutan and lndonesia at the expense of hard eamed foreign cunencies; while the

aggregates required for the main bridge construction was fumished from the local source of

Sylhet and Panchagarh.

Fortunately, Bangladesh has an underground hard rock deposit of considerable size in

Maddhapara, located in the northwestem part of Bangladseh under Dinajpur district. The

mine is operated by Maddhapara Granite Mining Company Limited (MGMCL), a

company of Petrobangla under the Ministry of Power, Energy & Mineral Resources,

Government of the People's Republic of Bangladesh. The company was incorporated on

August 04, 1998 with a paid up Capital of Taka 350 Crore under Company Act. of 1994.

The mine is designed to produce 1.65 million M. tons of hardrock per annum (daily

production capacity of 5,500 M. tons) to meet the requirement of flood control,

construction of coastal and town protection embankment, construction and maintenance

of bridges, roads & highways, embankment, river training, railway ballast, high rise

buildings decorated tiles and other heavy construction works undertaken by different

Government entities e.g. Bangladesh Bridge Authority, Public Works Department, Roads

& Highways Department, Water Development Board, Bangladesh Railways etc.

The hardrock from the underground mine is transported throu$h two vertical shafts.

Rocks are then screened, crushed, washed and sorted for marketing. These are

prepared in different categories such as, Boulder (250 mm & above), Crushed Stone (05-

20 mm, 2040 mm,40-60 rnm, 60-80 mm) and Stone Dust (00-05 mm).

MGMCL has formally requested the Department of Civil Engineering, Bangladesh University

of Engineering and Technology (BUET) to prepare a report in the suitability of the

Maddhapara hard rock as an ample source of coarse aggregate for local constructions.

MGMCL further requested BUET to investigate the potential of using their Stone Dust

in cement and bituminous concrete. This report thus investigated the physical and

engineering properties of Crushed Stone (article-2) and then use of Stone Dust in

cement concrete (article-3) and bituminous concrete (article-4).

2. PHYSICAL AND ENGINEERING PROPERTIES OF CRUSHED STONE

;

The physical and engineering properties of Crushed Stone aggregate required for

various construction works are investigated. The physical properties investigated are

grain size analysis, bulk specific gravity, unit weight, water absorption, flakiness index,

elongation index, percent clay lump & friable particles, percent materials finer than sieve

# 200. The engineering properties of the aggregates investigated are Los Angeles

abrasion value, aggregate impact value, aggregate crashing value, 10% fines value and

percent loss in sodium sulphate soundness test. Test results are included in Appendix-A.

The standards related to the aggregate characteristics set by Roads & Highways

Department, Bangladesh Railway and some internationally reputed institutions such as,

American Standards for Testing Materials (ASTM), American Concrete lnstitute

(ACl), American Association of State Highway and Transportation OfficialsHage I 3

a?

,

trIIIII

(AASHTO), Transportation Research Laboratory (TRL) UK, etc. are presented in the

Table 1 and Table 2 along with the corresponding test results for the Maddhapara

Crushed Stone. From the table, it is observed that for all the available standards,

Maddhapara Crushed Stone meet the required specification for use in railway tracks,

highway pavements and cement concrete works.

3. CEMENT CONCRETE MIX DESIGN

Tfe Stone Dust was then mixed with Crushed Stone to produce 32 MPa and 38 MPa

cement concrete mix. The mix design reports are included in Appendix-B.

4. BTTUMTNOUS CONCRETE MIX DESIGN (MARSHALL METHOD)

The Stone Dust was then also mixed with Crushed Stone to produce bituminous concrete

for use in medium traffic areas. The mix design report is included in Appendix-C. Sample'1

was prepared mixing 65% of @urse aggregate ,30o/o of fine aggregate and 5% of mineral

filler. Sample-2 was prepared mixing 70o/o of course aggregate ,25o/o of fine aggregate and

5% ol mineralfiller. !n both the cases 80-100 penetration grade bitumen was used.

5. CONCLUDING REMARK '

The Crushed Stone from the Maddhapara hard rock meets the standards set by various

agencies for different construction purposes. Therefore, its use in both private and public

sector construction projects can be recommended. ln this context, it can mention here

that the. Bangladesh Railway has already started to use Maddhapara hard rock as stone

ballast. Further, the Civil Aviation Authority of Bangladesh (CAAB) has approved

Maddhapara hard rock mine as source of course aggregate"for bituminous overlay

construction at Hazrat Shahjalal lntemational Airport (HSIA), Dhaka. The Stone Dust can

also be used in both cement and bituminous concrete. But mix design should be performed

to assess it's appropriate proportion to get desired results.

BITUMINOUS HOT-MIX DBSIGN BY MARSHALL METHOD

Design Reouirements:

Dense graded Hot-Mix Asphalt (flMA) wearing course to be used in a mediurn traffic area. The

mixture contains a 25mm nominal maxirnum particle size aggregate. The adopted gradation for the

combined mineral aggregate of crushed stone and crushed stone are attached with this report. A 80-

100 penetration grade asphalt was used in the laboratory for design.

INTRODUCTION

We were instructed to carry out chemical analysis of a sample of granite aggregate advised lo have beenextracted from the above sile in accordance with the method cited in ASTM C289-2007. The purpose of theanalysis was to ascerlain the potentialalkali-silica reactivity of the granite by the chemicalmethod.

The results presented in this certificate relate only to those samples tested by QED. No responsibility is taken for the accuracy ofsampling unless this is performed under our own supervision. Opinions and interpretations expressed are the consultant's view basedsolely on his/her assessment of the samples 'as received'.
