Abstract

In Construction Industry Brick Masonry plays an important role. This study deals with the significant of the Natural Masonry Behaviour in various composition condition, the Cement Mortar Bricks and Clay Bricks variations have initiated the addition of waste materials in it.Therefore the various materials like Wheat Husk ash, and Saw dust in cement mortar and Egg Shell in clay mortar were used, thenit is proceed for compressive strength of the Clay bricks and Cement Mortar bricks. The bricks are tested for the 7 days and 28 days analysis of the test. By using this we can reduce the certain amount of cement, fine aggregate and clay. Then we can get the bricks in low cost. The main aim is to reduce the emission, cost of the bricks and to attain good strength.

Introduction:

In many countries the brick is used in all the part of the building. Due to its good heat insulation it was used widely in the construction fields. The brick has the Good compressive strength and it has easy availability. The good bricks will be found by using its good soundness, durability and its cost is also less. So it is widely used in all countries. And it is non- homogeneous, inelastic and it is described as orthotropic. In this project, we have executed the formation of bricks with different form of various waste materials and executed the project.

Therefore various studies were referred and analysed by the compression behaviour by using the UTM machine and Compression testing machine which is used for checking the compression strength. The experiment is carried out by using 1.5 ratio.

Methodology:

Material’s used:

1. Cement

2. Fine aggregate 3. Wheat husk ash 4. Saw dust 5. Clay

6. Egg shell powder Properties test on materials:

Cement:

Cement is used as a binding material. According to IS 456 2000, OPC 53 grade is adopted.

According to IS 12269 1987, the physical test for cement is carried out.

6 Compressive Strength 36 M pa Fine Aggregate:

According to IS 383 1970, the manufactured sand is confirmed and adopted to this project.

By crushing the hard granite stone the manufactured sand is produced. And hence it is a replacement for river sand.

Saw Dust:

While shaping the wood for making the furniture, the wastages of dust will be appeared.

That wastages is known as saw dust, the material used in this project.

Clay:

Clay is a naturally available material and it is available in most of the villages. And hence we have adopted the clay.

Egg shell powder:

Now-a-days we are consuming egg in our daily food. We are just consuming the inner part

Mix Proportion:

In this study, the cement and fine aggregate is mixed together to attain certain strength.

The mix ratio cement mortar is 1:4. The adopted dimension is 19x19x9 cm. Then the clay is used for another set of the specimen.

Scope of the project:

For cement mortar brick, the adopted mix ratio is 1:4. Cement is added with wheat husk ash. By adding wheat husk ash as 3%, 6%, 9%, 12% as a partial formation of cement, saw dust is added with fine aggregate. 10%, 15%, 20%, 25% were added as a partial formation of fine aggregate.

For clay brick, the adopted mix proportion is 1:4. The experiment is carried out by adding the egg shell powder. Along with that, egg shell powder is also used as a partial addition of clay.

8% of egg shell powder is used in this project.

Specimen Preparation:

Cement mortar brick:

Type 1 Type 2 Type 3

The cement mortar brick contains the materials of cement, fine aggregate, and wheat husk ash and saw dust. The adopted mix ratio is 1:4. By mixing these materials, the experiment is carried out. The size of the brick is 9x4x3 inches. By adding the various materials like wheat husk ash and saw dust we casted the 3 different shaped bricks. They are varied in the sizes.

Clay bricks:

The clay brick contains the materials of clay, egg shell powder. The adopted mix ratio is 1:4. By adding these materials the proportional quantities be will assigned. The size of the brick is 9x4x3 inches.

Compression test:

Compression Test for Mortar Bricks:

By adding suitable recycling wastes the preparation was made. The form of the brick preparation was carried out by using this formation. It will assure the specimen. It is observed that the brick is burnt well and to reform the following category that they have tested by using Compressive testing machine. It should attain the correct burning formation then only thecompression strength will be successful. It is observed for 7 days and 28 days.

Results and Discussion:

 By using the Cement Mortar we have got more strength.

 By increasing the saw dust and wheat husk ash the compression strength gradually increased. Usually the clay has more strength, it just increased its capability while adding the egg shell in it.

 The type 1 brick achieved its strength while adding 12% of the Wheat Husk ash and Saw dust powder.

 The type 2 brick achieved its strength while adding 9% of the combination.

 The type 3 brick achieved it strength while increasing the content to 6%.

 The flow has increased up to 25% by the use of cement mortar.

 By use of clay it has increased up to 23%.
