ABSTRACT

 

This paper examines the possibility of using the combination of waste Sheet Glass Powder as fine aggregate and Portland cement with 20% optimum replacement of flyash as cementitious binder offers an economically viable technology for high value utilization of industrial waste. Using of SGP in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources. Natural sand was partially replaced (10%, 20%, 30%, 40% and 50%) with SGP and 20% optimum replacement of flyash in Portland cement. Compressive strength, Tensile strength (cubes and 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 SGP were also studied. The test results indicate that it is possible to manufacture low cost 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 up to 30% along with flyash 20% optimum in cement replacement can be used respectively.

 

Keywords : Sheet Glass powder, Flyash, Fineness Modulus, Compression strength, Tensile strength, Flexural strength.
