4、  Abstract:  Sheet glass powder (SGP) used in concrete making leads to greener environment. In shops, near by Chidamba-ram many sheet glass cuttings go to waste, which are not recycled at present and usually delivered to landfills for disposal. Using SGP in concrete is an interesting possi

5、bility for economy on waste disposal sites and conservation of natural re-sources. This paper examines the possibility of using SGP as a replacement in fine aggregate for a new concrete. Natural sand was partially replaced (10%, 20%, 30%, 40% and 50%) with SGP. Compressive strength, Tensile strength

6、 (cubesand cylinders) and Flexural strength up to 180 days of age were compared with those of concrete made with natural fine aggregates. Fineness modulus, specific gravity, moisture content, water absorption, bulk density, %voids, % porosity (loose and compact) state for sand (S) and SDA were also

7、studied. The test results indicate that it is possible to manufac-ture concrete containing Sheet glass powder (SGP) with characteristics similar to those of natural sand aggregate concrete provided that the percentage of SGP as fine aggregate is limited to 10-20%, respectively.   Key Words: &nb

9、ste 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 place called Chidambaram where most of the col-ored sheet glasses from windows are packed as a waste andsent

10、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 materials like natural sand are also becoming rare 5. Attempts have been made for a long time to use waste glasses

11、as an aggregate in concrete, but it seems  that the  2 concrete with waste glasses always cracks 2, 6. Very limited work has been conducted for the use of groundglass as a concrete replacement 7. These waste storage  disposals are becoming a serious environmental problem especially fo

12、r 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 from the riverbeds. How-ever, the availability of river sand for the preparation of

13、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 identification of substitute materials for the river sand for making concre

14、te. 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 concrete made with Sheet Glass powder concrete. Natural fine aggregate is su

15、bstituted 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 materials and Sheet Glass Powder are also studied.  MATERIALS AND METH

16、ODS The 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 Chidambaram taluk at Cuddalore District. Sheet Glass is converted into fine

17、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 powder is shown in Fig. (5). Sheet glass Powder using sieve size from

18、 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 SGP, (S+10%SGP), (S+20%SGP), (S+30%SGP), (S+40%SGP) (S+50%SGP) and

19、 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 physical properties of SGP andFine and coarse aggregate. Table 3 shows ch

20、emical 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 41 Mpa. The sand was replaced with 10%, 20%, 30%, 40%, and 50% SGP.
