#water absorption

Now days the use of clay bricks in building construction is widely used. Such a time clay bricks to be used in better option of building construction as examining compared to the conventional clay bricks which is made by only on clay bricks in a cost view of point and better suitability. India is a developing country so here the construction of compound walls and building plays an important role. Nowadays most of the work related with building is done. Thus the clay bricks is light weighted and then to be used another option of prefabricated compound wall construction. This experimental investigation design bricks by using Indian standard code of dimension 230mm x 110mm x 75mm. In this project main mix design proportions is 2 , 3 , 6 and 9 of sawdust with jaggery water mixer. Ultimate aim of this study is to increase the compressive strength and weight to be reduction of clay bricks and to reduce the waste materials available in saw mills and timber industries. Then the water absorption to be noted and examine strength comparison in the specimen tests. 

The plastic waste is the hazardous problem in today's world. This is most dangerous problem in front of humanity. The most hazardous type of wastes are HDPE and PTE and the plastic below 50micron is also causing a serious problem. These plastic mixed in the soil, it directly effects on fertility of the soil. Nowadays, the large amount of plastic is deposited into sea. This plastic wastes gives hazardous effect on the aquatic life and quality of seawater also polluted by this plastic. So, we try to finding efficient way to solve this problem of plastic waste. So, we added this plastic wastes into the bricks and create the bricks by using plastic wastes. It is most economical solution present in the construction industry and it is also economical and environment friendly solution of the plastic wastes. 

There is need for tested and proven alternative source of alternative walling materials in third world countries such as Nigeria. This will foster massive provision of houses for the populace. The aim of this research is to compare the properties of cement stabilized lateritic bricks sourced from different locations. Soil samples were taken from three locations within the study area to laboratory for Abrasion, Impact, Compressive strength and Water absorption tests. Results showed that the stabilized lateritic bricks A, B and C have water absorption values varied from 17 to 23 , 32 to 36 and 38 to 42 respectively for 7 - 28 days at 1 cement content. For 2 cement content, water absorption values varied from 15 to 20 , 24 to 28 and 32 to 36 for lateritic bricks A, B and C respectively. While sandcrete block has water absorption values varied from 9 to 13 for 7 - 28 days respectively. It is also observed that stabilized lateritic bricks A, B and C have compressive strength values varied from 1.33 to 1.71N mm2, 0.32 to 0.42 N mm2 and 0.21 to 0.29N mm2 respectively for 7 - 28 days at 1 cement content. For 2 cement content, compressive strength values varied from 1.52 to 2.09 N mm2, 0. 40 to 0.63N mm2 and 0.29 to 0.35 N mm2 at 7 - 28 days for lateritic bricks A, B and C respectively. While sandcrete block has compressive strength values varied from 0.54 to 0.74 N mm2 for 7 to 28 days respectively. The higher the cement content, the lower the absorption rate and the higher the compressive strength. The compressive strength also increases with age. Lateritic brick is more cheaper than sandcrete block for construction of building because it require little cement content. Further study should be conducted for another source of stabilizer.
