Abstract: These days, numerous scientists from everywhere over the world, concentrating on methods of utilizing agriculture and industrial waste as raw material in the construction industry. By the innovation of technologies and ideas certain waste as raw materials has also been used in construction industries. This venture depends on A sugarcane bagasse ash (SBA) is one of such waste materials conveying natural contamination. For this reason, materials were gathered and its essential properties were assessed at the beginning stage. The Principal focal point of this investigation is to evaluate the fresh and hardened properties by supplementing 0%, 5%, 10%, 15% of sugarcane bagasse ash as a substitution of concrete and 1% polypropylene fiber as an admixture in concrete. The test outcomes indicated better outcomes in the compressive and split tensile strength of 10% sugarcane bagasse ash concrete. The compressive strength and split tensile strength was reduced on 15% substitution of sugarcane bagasse ash was clearly viewed.

1. INTRODUCTIONConcrete is the most widely used construction material having several

desirable properties like high compressive strength, stiffness, durability and low coefficient of thermal expansion under usual environmental conditions. The concrete when exposed in the environment expands and contracts freely due to temperature and leads cracks on its surface. It creates tension in concrete. The usage of the Industrial and Agriculture waste products in concrete gives better results. The focus of waste reduction from the environment is used as raw materials in cement and concrete Production. The sugarcane bagasse ash is one such waste product of sugar mills and the sugar refining industry. The bagasse ash has alumina and silica compounds. It is used as a raw material in cement production. The use of bagasse ash in concrete partial replacement of cement not only reduces the cost but also improves the properties of concrete and reduces environmental pollution.

In addition in this evaluation the polypropylene fibers are also added for concrete mix. Polypropylene fiber is a material made from fine fibers of light weight, extremelystrong material. The addition of polypropylene fiber into cement mortar eliminates cracksand shrinkage in the surface.

Bagasse ash is partially replaced in the ratio of 0%, 5%, 10%, and 15% by weight of cement in concrete and 1% Polypropylene fiber as admixture with M25 concrete mix. The Compressive strength and split tensile strength test at the age of 7 and 28 days is studied

2. Materials used for investigation

2.1 Cement

Pozzolanic Portland cement (PPC) of 53 grade is used for the entire work and care has been taken that it has to be stored in airtight containers to prevent it from being affected by the atmospheric and monsoon moisture and humidity. It has specific gravity of 3.15 and Fineness of 6 %.

2.2 Bagasse ash

Bagasse could also be a by-product from sugar industries which is burnt to create power required for various activities within the factory. The burning of bagasse leaves bagasse ash as a waste, which features a pozzolanic property that might potentially be used as a cement replacement material. The Tabel.1 shows the composition of Bagasse ash [3]

7 Loss on Ignition 0.71

2.3 Fine Aggregate

The river sand, passing through 4.75 mm sieve and retained on 600 μm sieve, conforming to Zone II as per IS 383-1970 was used as a fine aggregate in the present study. The sand is free from clay, silt and organic impurities. The fine aggregate has fineness modulus of 0.378 and specific gravity of 2.45 in accordance with IS: 2386(Part- I)-1963

2.4 Coarse Aggregate

The crushed stone of 20 mm size is used for the study. The coarse aggregates are well sieved and the other properties are examined. The specific gravity of coarse aggregate is 2.80.It has fineness modulus of 0.138 as per IS: 2386(Part- I)-1963.

2.5 Polypropylene Fiber



The polypropylene fiber is a rapidly growing member of synthetic fiber. It is light in weight and gives a good offer against toughness. The best energy absorption property effectively reduces the cracks in the concrete structures.

3. Concrete Mix and Mix Proportion

The concrete of grade M 25 of 1: 1.3: 2.2 and with constant water cement ratio of 0.4 is used for present investigation. The various percentages of mix proportions of concrete mix with replacement with bagasse ash by cement is tabulated in the Table.2

The following Conclusions are made from the test result,

• From the observed Slump Values the mix is identified as medium workability concrete. It shows the concrete is suitable for reinforced concrete structure construction.

• Based on the Consistency test the concrete is dry mix and has low workability. So it needs vibrator to achieve better workability.

• The optimum compressive strength is obtained at 28.78 MPa with addition of 1% polypropylene fibers and 10% replacement of cement by bagasse ash.

• The optimum split tensile strength is obtained at 2.97 MPa with addition of 1% polypropylene fibers and 10% replacement of cement by bagasse ash.

• The waste Sugar Cane Bagasse ash is advantageously used as a replacement of cement upto 10 % in the preparation of concrete.
