Abstract In this research we analyze the strength of concrete made with using locally available fly ash based Cement by using two waste materials one is Glass Powder and Other is Stone dust. The Glass Powder is used as 20% replacement of the cement and Stone Dust as the partial replacement of Fine Aggregate from 0%, 10%, 20%, 30% and 40%. The grade of the concrete here is M25 and M30 grade. Slump Test was carried out for the fresh concrete whereas Compressive Strength, Flexure Strength and Split Tensile Tests were carried for the Hardened concrete. All tests are done at 7, 14, 28, and 56 days with 0 to 40% replacement of sand at an interval of 10%. Again above tests are carried out with 20% replacement of cement by glass powder. It is observed that the glass powder improve the strength and stone dust can be used as sand. This is great saving in costly material.

  1. INTRODUCTION

    The concrete is useful materials in the construction industry. It is not only used in building construction but also in other areas like roads, bridges, harbors, and many more. It is comparatively economical, easy to make offers continuity solidity and indeed it lays the role of developing and improving or modern life.It is a composite material which is made up of cement, sand, aggregate and water. The fresh concrete can be mould into any desire shape. The life of the concrete is very high so it can be used as versatile material. In the concrete the cement is used as the binder material which has the binding tendancy. Due to increase in activities for different regions and utilities scaring of the naturally available resurces is being forced due to its over exploitation. This is the threat to the environment. Also the use of conventional material becomes costly day by day. Hence conservation of the naturally available material is great challenge for the civil engineers. Which also reduced the cost of the material or by using the alternateve material which reduced partially or fully the conventional material. There is only way to search materials which can fully or partially replaced naturally available material in the construction field.

    The various alternative materials are used as partial for fully replacement of conventional material e.g. fly ash, cocomut shell, crushed sand, recycled aggregate etc. Here we use the two waste material which is easily available.

    The stone dust produced from stone crushing zones appers as a problem for effictive disposal. Also the land over which demolition wastes are disposed, deprives the further land use forever for other purposes. Which is used here as partily replacement as fine aggregate. Also the glass powder produced from the many industries is also a waste material which can be used as partial replacement as cement. Sand is a material used in concrete as fine aggregate.

Stone Dust Glass powder

Waste glass powder in this study was used from locally available market. Glass waste is very hard material. The glass powder if ball pulverized and particles size are less than 150 m and sieved through 75 m.

Water

The clean portable water is used in this experimental work without any visible impurities.

In this experiment we select the two grades of concrete M25 and M30. The mix design was carried out as per IS: 10262-2009. The trials have been prepared and finally we find for M25 grade was design for this experiment having the mix proportion 1:1.40:3.05 and the water cement ratio is 0.45. M30 grade was design for this experiment having the mix proportion 1:1.32:2.85 and the water cement ratio are 0.43. All locally available materials are used during the preparation of the mix proportion.

Mixing and casting of samples

The mixing and casting were done with proper care and all materials were weighted properly and mixed in laboratory concrete mixer. The water is added after all materials are feed into in mixer in proper order. The cubes were filled and compacted by using table vibrating machine and the cylinder and beams were compacted using the tamping rod for around 25 times. The moulds were levelled properly. The specimens were kept for 24 hours and then it is removed from mould and kept in curing tank till the testing days. All specimens are tested at 7, 14, 28, and 56 days.

Compressive Strength Tests

The compressive strength tests were done by using the cubic specimen of sizes 150x150x150 mm. The moulds are confirming to the IS specification. For each test three specimens were taken and their average value is considered. The load should be applied gradually at the rate of 140 kg/cm2 per minute till the specimens fails. The load at the failure divided by area of specimen gives the compressive strength of concrete. The cubes were tested at 7, 14, 28, and 56 days of curing.

Flexure Strength Tests

The flexure strength also known as modulus of rupture, bends strength, or fracture strength. The value of modulus of rupture depends on the dimensions of the beam and manner of loading. The value of the flexural strength is about 10 to 20 percent of compressive strength depending on the type, size and volume of coarse aggregate used. In these tests the beams were casted having the size 150x150x700 mm. For this the moulds of the same sizes are taken which are confirming to the IS specification. During the casting it is compacted by using the tamping

rod of around 25 times the diameter of the tamping rod is 16 mm. The flexure strength was tested at the age of 7, 14, 28 and 56 days curing.

Split Tensile Tests

We know that the concrete is weak in tension. The tensile strength is one of the important properties of the concrete. The tensile strength tests the cylinders were casted having the size 150 mm diameter and 300 mm lengths. This is the indirect method of the testing the tensile strength of the concrete. For this the moulds of the same sizes are taken which are confirming to the IS specification. It is also casted by using the 16 mm tamping rod of around 25 times. The split tensile tests were carried out at 7, 14, 28 and 56 days curing.

  2. CONCLUSION

    From the about experiments following conclusions are observes:

    1. The compressive strength by replacing 40% sand by stone dust the strength increases by 10, 5, 13 and 14% at 7, 14, 28 and 56 days respectively in M-25 concrete and 9, 8, 12 and 10% at 7, 14, 28 and 56 days respectively in M-30 concrete. As compared to the conventional concrete. Thus stone dust increases the compressive strength of the concrete and reduce the cost of material and also its great use of waste materials.

    2. The compressive strength of the concrete by replacing the 40% sand by stone dust and 20% cement by the glass powder the strength increases by 28, 15, 18 and 24% at 7, 14, 28 and 56 days respectively in M-25 concrete and 30, 15, 12 and 8% at 7, 14, 28 and 56 days respectively in M-30 concrete. As compared to the conventional concrete. Thus glass powder can also be used up to 20% which is also great saving in costly cement and use of waste material.

    3. The flexure strength of the concrete by replacing the 40% sand by stone dust increase 18, 28, 29 and 30% at 7, 14, 28 and 56 days respectively in M-25 concrete but in M-30 concrete it increases 12 19 and 23% at 7, 28 and 56 days respectively and reduced by 1.2% at 14 days. As compared to the conventional concrete. Thus stone dusts also increase the flexure strength at the later ages of the concrete.

    4. The flexure strength of the concrete by replacing 40% sand by stone dusts and 20% cement by the glass powder the strengths are increase by 37, 35, 44 and 43% at 7, 14, 28 and 56 days respectively in M-25 concrete and 19, 18, 42 and 44% at 7, 14, 28 and 56 days respectively in M-30 concrete. As compared to the conventional concrete. Thus flexure strength is also increase by including the glass powder. It also reduces the consumption of the cement.

    5. The split tensile strength of the concrete by replacing sand 40% by stone dust the strengths increases 9, 17, 14 and 16% at 7, 14, 28 and 56 days respectively in M-25 concrete and 15, 2, 9 and 10% at 7, 14, 28 and 56 days respectively in M-30 concrete. Hence stone dust

      increases the tensile strength of the concrete which is also saving in fine aggregate.

    6. The split tensile strength of the concrete by replacing 40% sand by stone dust and 20% cement by glass powder the tensile strength is increase 24, 24, 14 and 13% at 7, 14, 28 and 56 days respectively in M-25 concrete and 5, 6, 8 and 8% at 7, 14, 28 and 56 days respectively in M-30 concrete. Hence by adding the glass powder with stone dust is also increase the tensile strength of the concrete. Hence saving in cost is two ways cost of sand and cement.

  3. FURTHER SCOPE OF WORK

    1. The study can by carry out by increasing the percentage of stone dust up to 100% and fully replacement of the fine aggregate.

    2. The study can also be carry out by increasing the percentage of glass powder up to maximum level with or without stone dusts.

    3. The engineering properties like water absorption, reduction in weight of concrete and density of the concrete can be study by using the stone dust and glass powder.

    4. The effect temperature and humidity can also be study.

    5. The study can also be carry out by using higher grade of concrete.
