7、 is of large volume and is increasing year by year in the Shops, construction areas and factories. Using waste glass in the concrete construction sector is advantageous, as the production cost of concrete will go down 1. Waste glasses are used as aggregates for concrete 2-4. In Chennai there is a pl

8、ace called Chidambaram where most of the col-ored sheet glasses from windows are packed as a waste andsent to landfill. The plain sheet glasses can be recycled, but itis costly to remove the color of colored glasses and recycle again. Estimated cost for housing is more and some construction material

9、s like natural sand are also becoming rare 5. Attempts have been made for a long time to use waste glasses as an aggregate in concrete, but it seems that the concrete with waste glasses always cracks 2, 6. Very limited work has been conducted for the use of groundglass as a concrete replacement 7. T

10、hese waste storage disposals are becoming a serious environmental problem especially for Chidambaram where place disposal sites are lacking. Hence there is a need for recycling more and more waste materials. The most widely used fine aggregate for the making of concrete is the natural sand mined fro

11、m the riverbeds. How-ever, the availability of river sand for the preparation of con-crete is becoming scarce due to the excessive nonscientific methods of mining from the riverbeds, lowering of watertable, sinking of the bridge piers, etc. are becoming common treats 5. The present scenario demands

12、identification of substitute materials for the river sand for making concrete. Recently, some attempts have been made to use ground glass as a replacement in concrete 8-10. The objective of this paper is to present the results of experimental investigations on Physical and Mechanical properties of c

13、oncrete made with Sheet Glass powder concrete. Natural fine aggregate is substituted by weight by Sheet Glass Powder at rates varyingfrom 10, 20, 30, 40 and 50 percentages. Compressive, Ten-sion, and flexural strength are evaluated and compared up to180 days of ages. Specific Properties of concrete

14、materials and Sheet Glass Powder are also studied.MATERIALS AND METHODSThe raw materials, used for this study are natural coarse aggregate, fine aggregate, Sheet glass Powder (SGP) aggre-gate and 53 grades Portland cement. The Sheet glass used forthis study was collected from the points in Chidambar

15、am taluk at Cuddalore District. Sheet Glass is converted into fine aggregate as shown in flowchart Fig. (1) and the procedure for making Sheet Glasscrete is shown in flowchart Fig. (2). Sheet Glass collected from shops is shown in Fig. (3), Sheet Glass crushed is shown in Fig. (4) and Sheet glass po

16、wder is shown in Fig. (5). Sheet glass Powder using sieve size from 4.75mm onwards is shown in Fig. (6). Table 1 shows the Fineness Modulus results of S, SGP, (S + 10%SGP), (S + 20%SGP), (S + 30%SGP), (S + 40%SGP) and (S + 50%SGP). Fig. (3) shows the Fine aggregate material of grading curve and also

17、 SGP, (S+10%SGP), (S+20%SGP), (S+30%SGP), (S+40%SGP) (S+50%SGP) and 100%SGP. The sand used for the study was locally available river sand conforming tograding zone III of IS:383-1970. The coarse aggregate was a normal weight aggregate with a maximum size of 20mm IS:456-2000. Table 2 shows the physic

18、al properties of SGP andFine and coarse aggregate. Table 3 shows chemical charac-teristics of the SGP material. The control mix of the concrete was designed with a mix ratio of cement /water /Sand /Coarseof 1:0.48:1.66:3.61 by weight. This mix design yielded an average 28 days compressive strength 4

19、1 Mpa. The sand was replaced with 10%, 20%, 30%, 40%, and 50% SGP. EXPERIMENTAL PROGRAMME The SG (Sheet Glass) was collected from shops in Chidambaram and its properties were tested. Analysis was carried out in Concrete mixtures with 7 levels of SGP (Sheet Glass Powder) replacement ranging from 10%

20、to 50% and 100%. The specimens were cast and tested to study the possibility of using SGP as a substitute material for sand in concrete. The control mix, utilizing SGP, replaced as the fine aggregate, was designed for the cube, cylinder andbeam. Based on the laboratory trials, the mix proportion of

21、the control mix (M20) was finalized and investigated to de-termine the effect on compressive and tensile strength in cubes and cylinder. The mixture were 0%,10%,20%,30%, 40%,50% and 100% with different Sheet glass powder(SGP) replacement in fine aggregate is analyzed. It is also used to investigate

22、the effect of SGP replacement on Flex-ural strength.Tests to determine specific gravity, moisture content , water absorption, Bulk density, Compressive and Tensile strength of cubes and cylinders, SGP was used to replace 0to 50% and 100% of the sand by weight. For compressive and tensile strength te

23、sts 150 x 150mm cubes and150 x300mm cylinders specimens were used. A total of 500specimens were cast and cured in water at room temperature in the laboratory for 28,45,60,90,180 days. At the end of each curing period, three specimens for each mixture were tested for Compressive, Tensile and Flexural

24、 strength andthe average was recorded. Flexural strength was measured using 100x100x500 mm beam specimen in the centre of the beam load applied. A total of 90 beams were cast and cured in water for 28,45,60, 90,180 days. For each mixture, three beams were loaded to failure, and the average strength

25、was recorded in each caseRESULTS AND DISCUSSION Workability of the concrete increased as the percentages of SGP replacement increased, but it later decreases as the curing days increases because of alkali silica reaction. The density of the concrete 2531 kg/m3 at 0% replacement of SGP decreased but

26、at 100% the density increased to 2689kg/m3for cube at 28 days curing. Fig. (3). sheet glass Fig. (4). Crushed sheet glass Fig. (5). sheet glass powderFig. (6).

Concretes containing SGP as fine aggregates, with a mixing ratio of 30%, 40% and 50% displayed a reduction in compressive strength than that of plain concrete respectively. This tendency towards a de-cr

30、ease in compressive strength with an increase in mixing ratio was repeated for concretes 180 days of age. At 10%, 20% and 100% mixing ratio there was increase in strengththan that of plain concrete. In any case, the SGP as fine ag-gregate in concrete showed a decrease in strength as the cur-ing days

31、 increased but at 10% and 100% the strength as con-crete is more than that of conventional concrete.

Concretes containing SGP as fine aggregates, witha mixing ratio of 30%, 40% and 50% displayed an increase in Tensi

This tendency towards a decrease in tensile strength with an increase in mixing ratio was re- peated for concretes 180 days of age. At 10% and 100% mixing ratio there was an increase in strength than that of plain conc

The concrete containing SGP as fine aggregate, at a 10-20% mix-ing ratio, showed a slight increase in the flexural strengthwhile that of plain concrete. At 30%, 40%, 50% and 100% mix

36、ing ratio there was increase in strength than that of plainconcrete.

Fig. (15) explains the relationship between tensile strength of cubes and the tensile strength of cylinders of the concrete containing SGP as fine aggregate and Table 4 gives the details of regression equations.CONCLUSIONFrom the tests conducted on SGP replaced in fine aggre-gate for

38、concrete as presented in various sections, the follow-ing conclusions are made: The SGP is suitable for use in concrete making. The fineness modulus, specific gravity, moisture content, un-compacted bulk density and compacted bulk density at 10% Sheet glass powder(SGP)were foundto be2.25,3.27,2.57%,

39、1510kg/m3 and 1620kg/m3For a given mix, the water requirement decreases as the SGP content in-creases. The compressive strength of cubes and cylinders of the concrete for all mix increases as the % of SGP increases but decreases as the age of curing increases due to alkali silica reaction. The Tensi

40、le strength of cubes and cylinders of the concrete for all mix increases than that of conventionalconcrete age of curing and decreases as the SGP content in-creases. The Flexural strength of the beam of concrete for allmix increases with age of curing and decreases as the SGP content increases. 100%

41、 replacement of SGP in concrete showed better results than that of conventional concrete at 28days and 45 days curing but later it started to decrease its strength because of its alkali silica reactions. The density of SGP concrete is more that of conventional concrete. SGP is available in significa

42、nt quantities as a waste and can be util-ized for making concrete. This will go a long way to reduce the quantity of waste in our environment.
