“…However the control sample 0% FCC and the 10% FCC have a better water absorption property of 85kg/m 3 while the water absorption rate for the 20% FCC and 30% FCC were 120kg/m 3 and 90kg/m 3 respectively. This means that 10% FCC can be use in water logged areas and get same result as when using the normal sandcrete blocks without any addition of shredded polythene bags waste as reported by [10,12]…”

“…Also, the process of fly ash brick manufacturing results in lesser pollution. A studies by [10,11,12] on the possibility of using polythene fibres to increase the strength of sandcrete blocks without increasing the weight and cost of production with the addition of 0.25%, 0.5% and 0.75% shredded polythene bags, revealed that the addition of polythene fibre to sandcrete blocks has very little effect on the compressive strength, although at 0.5% fibre content, the tensile strength increased. They study further reported that the compressive strength of the heated blocks is higher than the non -heated blocks.…”

The need for maximum disposal of wastes and conservation of scarce resources or materials into useable building materials need to be underscored. Therefore, this study attempts to evaluate the use of polythene bag wastes in the building industry. The polythene bags waste (pure water sachets bags) were collected in dumping sites in Yola metropolis and were manually shredded to about (5 x 10) mm sizes. Fired Cement clay (FCC) bricks incorporating the polythene waste were produced at a mix ratio of 1:8 and water/cement ratio of 0.5. Samples were tested for compressive strength at 7, 14, 21 and 28days hydration period while the water absorption and thermal conductivity test were evaluated at 28 days hydration period. Result of the compressive strength for the FCC Bricks at 28 days hydration period was between 0.00 and 2.33N/mm 2 , with 10% FCC having the highest compressive strength and least water absorption values of 2.01N/mm 2 and 85 Kg/mm 3 respectively. The compressive strength and thermal conductivity of all sampled FCC bricks decrease with increase percentage content of shredded polythene bags waste. The study found that thermal conductivity values of the FCC bricks was in the range of 1.48w/mk and 1.8w/mk. The study therefore recommends 10% FCC as suitable for use in areas where thermal transfer and rising dampness is of interest. Furthermore, the study concludes that reuse of the polythene bag wastes as building material or resources will help in reducing environmental hazards.

Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and in expensive to produce, has led to its widespread use. Research approach: an evaluative research approach, research design: in this study pre experimental one group pre test post test design was be used. this design is widely used in educational research, research sample: in this study sample was the school age children in community rural area of Indore, sample size: 50 school age children, sample techniques: non probability purposive sampling technique. The mean pre test and post test 11.8 and 17.9 and mean difference 6.1 that there was a significant difference between pre test and post test knowledge score hence H0 rejected and H1 is accepted.So it can be concluded that the school age children residing in Bawliya Khurd community have inadequate knowledge regarding harmful effects of polythene and plastic materials on environment and health and Structured teaching programme is an effective teaching strategy to increase their knowledge regarding harmful effects of polythene and plastic materials on environment and health.

“…Incorporation of short discrete steel fibres in a relatively hollow sandcrete blocks matrix, might gives the hollow sandcrete blocks materials a maximum ductility to overcome its low tensile strength properties. Similarly [14] reported that addition of polythene fibres to sandcrete blocks improves the tensile strength and limit the propagation of cracks, although it has little effect on the compressive strength. Recycled tyre steel fibres are obtained from recycling of scrap tyres [15].…”

This study investigates the effect of tyre steel fibres on compressive strength of hollow sandcrete blocks. A total of 36 number 450mm x 225mm x 225mm hollow sandcrete blocks with 0%, 1%, 2 %, and 3% of tyre steel fibre content were produced and tested for density, compressive strength and water absorption. From the test results, the densities of blocks increase with an increases in fibres contents. As at 28 days, the density increases from 1395.20 kg/m 3 for 0% to 1425.57kg/m 3 for 3% fibre content. Also, the water absorption decreases with increases in tyre steel fibres. Furthermore, the compressive strength increases with increase in tyre steel fibres contents. At 28 days, there was an increase in compressive strength of 6%, 58% and 95% for 1%, 2% and 3% fibre contents respectively. It is concluded that addition of tyre steel fibres significantly improves the performance of hollow sandcrete blocks.
