      1. INTRODUCTION

         In order to address environmental effects associated with fine aggregate manufacturing, there is a need to develop alternative binders to make concrete.

         Consequently extensive research is on going into the use of fine aggregate replacements, using many waste materials and industrial by products.

         In this study, finely crushed fluorescent tube light waste are used as a partial replacement of fine aggregate in concrete and compared it with conventional concrete.

         Fluorescent tube light waste was partially replaced as 10%, 20% and 30% tested for its compressive, Tensile and flexural strength up to 7,14 and 28 days of age and were compared with those of conventional concrete; from the results obtained, it is found that fluorescent tube light waste can be used as fine aggregate replacement material up to particle size less than 4.75mm.

         The recycling of fluorescent tube light waste, within concrete, and the landfill-bound constituents of the municipal waste. It is suitable for sustainable construction practices

         Ecological or environmental benefits of alternative materials include the diversion of non recycled waste from landfills for useful applications, the reduction in the

         Portland Pozzolana Cement (PPC)-53 grade was used for the investigation. It was tested for its physical properties in accordance with Indian Standard specifications.

2. Aggregate

   Locally available fine and coarse aggregates are used in the investigation. and coarse aggregate sieved to the required quantity of volume to the maximum nominal size of 20 mm. Care is taken to arrive the size of coarse aggregate ranging from 4.75 mm to the maximum nominal size of 20 mm.

3. Water

   Potable water available in Concrete and highway laboratory of department of civil engineering is used for mixing the concrete and curing the specimens.

4. Fluorescent Light Tube

It is crushed into powder by using single hand tool powder

Preliminary tests are carried as per IS standard on the material used for concrete like specific gravity, fineness, consistency, and initial setting time for cement. For fine and coarse aggregates tests such as sieve analysis, specific gravity, impact value, crushing value and abrasion value (Los Angeles) are conducted as per standards and results are tabulated.

The ingredients of concrete such as cement, fine aggregate, coarse aggregate of maximum nominal size of 20mm are weighed accurately using the platform weighing machine. The ingredients are mixed manually and adequate amount of water is added to the constituents of concrete .The mixing is done till to get uniform mix of concrete is obtained

1. DURABILITY STUDIES

   The durability of cement concrete is defined as its ability to resist weathering action, chemical attack, abrasion, or any other process of deterioration. Durable concrete will retain its original from, quality, and serviceability when exposed to its environment.

   1. Acid Test

      In order to assess the weight loss concrete cubes is exposed to chemical media. For acid test hydrochloric acid was prepared by mixing 5% of Hcl with one liter of water as per ASTM G20-8. After normal curing (28 days) cubes were taken out and weight of cube was noted. Than weighted cubes was immersed in the prepared hydrochloric acid for 30 days. After curing the cubes were taken out from acid and weight of cubes was noted. From this weight loss of cubes is calculated.

      Weight loss = Weight of cube after Normal Curing Weight of cube after taken from Acid

   2. Alkaline Test

      To assess the weight loss concrete cubes is exposed to chemical media. For alkaline test sodium hydroxide was prepared by mixing 5% of sodium hydroxide with one liter of water as per ASTM G20-8. After normal curing (28 days) cubes were taken out and weight was noted. Than weighted cubes was immersed in the prepared sodium hydroxide solution for 30 days. After curing the cubes were taken out and weighted. From this weight loss is calculated.

      Weight loss = Weight of cube after Normal Curing

      Weight of cube after taken from Acid

   3. Fire Resistant

   Three cubes of ceramic waste concrete in each percentage of replacement (0%, 10%, 20%, and 30%) are tested. After 28 days curing specimens are kept in an oven for about 120 hours at 250c

2. RESULTS AND DISCUSSIONS

   1. Compressive Strength of Concrete

      The cube specimens tested for compressive strength of hardened concrete at the age of 28 days. This test is considered one of the most important properties and is often used as an index of the overall quality of concrete. The ceramic waste aggregate 10%, 20%, 30% replacement significant improvement in strength of concrete. But more than 30% replacement fluorescent tube light waste aggregate slightly affects the compressive strength of concrete

   3. Fire Resistant

      Three cubes of ceramic waste concrete in each percentage of replacement (0%, 10%, 20%, and 30% ) after 28 days curing was kept in an oven for about 120 hours at 2500C.Under this exposure condition, no damage and no change in color observed to the specimen.

3. CONCLUSIONS

The following conclusions are drawn from the study on fluorescent tube light waste fine aggregate sand and they are applicable for the range of parameters and materials used in this study. Fluorescent tube light waste can be formed into useful fine aggregate. It is observed that there is a strength increase with addition of fluorescent tube light waste of 10% and beyond which there appears to be no specific enhancement in strength. This strength increase appears to be true for compressive and flexural strength.

A measurable increase in durability of the concrete with fluorescent tube light waste has been observed. The experimental study in total revealed a better performance of the concrete with respect to strength, acid resistance, alkali attack and sustainability under fire.

• The compressive strength of fluorescent tube light waste concrete with 10% replacement of fine aggregate is 22.20% higher than control concrete.

• The split tensile strength of fluorescent tube light waste concrete with 10% replacement of fine aggregate is .3% higher than control concrete.

• The flexural strength of fluorescent tube light waste concrete with 10% replacement of fine aggregate is 3.70% higher than control concrete.

• The weight loss due to acid attack of 10% replacement of fluorescent tube light waste concrete at 30 days were 1.3% respectively and hence low.

• The weight loss due to acid attack of 20% replacement of fluorescent tube light waste concrete at 30 days 1.8% respectively and hence very low.

• The weight loss due to acid attack of 30% replacement of fluorescent tube light waste concrete at 30 days 2.2% respectively and hence very low.

• The weight loss due to alkali attack of 10% replacement of fluorescent tube light waste concrete at 30 days .3% respectively and hence very low.

• The weight loss due to alkali attack of 20% replacement of fluorescent tube light waste concrete at 30 days 2.6% respectively and hence very low.

• The weight loss due to alkali attack of 30% replacement of fluorescent tube light waste concrete at 30 days 1.4% respectively and hence very low.

• The fluorescent tube light waste concrete specimen with different percentages of replacement of fine aggregate was exposed to a temperature of 2500C for 120 hours continuously. It was observed that there was no damage and no change in color under this exposure condition.

Thus, it concluded that the replacement of fine aggregate with fluorescent tube light waste up to 10% replacement reaches optimum level. However, more research studies are being made on the fluorescent tube light waste concrete necessary for the practical application as fine aggregate aggregate.
