Read the following statements and select the correct ones. (i) Ahmed Khan, a plastic sack manufactturer of Bangalore, in 1998, developed polyblend, a fine powder of recycled modified plastic. (ii) In collaboration with RV College of Engineering and Bangalore City Corporation, he proved that the mixture of polyblend and bitumen was better for road carpeting as it had better water repellent property. (iii) By 2002, more than 40 km roads of Bangalore were laid with the help of Khan's mixture (iv) Rag pickers who used to get 0.40 per kg of plastic waste started getting 6.00 from Ahmed Khan. (v) INnovation like polyblend might help the modern society from being smothered with plastic waste.

Which of the following statement is // are correct with respect to remedy for plastic waste? a. Polyblend is a fine mixture of recycled modified palstic. b. It is a zero-waste procedure c. It was due to the collaboration of town people of Arcata and biologistis of Humboldt State University d. A blend of polyblend and bitumen enhances bitumen's water - repellent properties and helps to increase road life

A : Polyblend is a fine powder of recycled plastics. R : The blend of polyblend and bitumen, helped to increase road life by a factor of three.

In Bangalore recycle plastic is modified as _______

Figure shows the relationship between tensile stress and strain for a typical material. Below proportional point A, stress is directly proportional to strain which means Young's moudulus (Y) is a constant. In this region the material obeys Hooke's law. Provided the strain is below the yield point 'B' the material returns to its original shape and size when the force is removed. Beyond the yield point, the material retains a permancnt deformation after the stress is removed. For stresses beyond the yeld point, the material exhibit plastic flow, which means that it continues to elongate for little increases in the stress. Beyond C a local constriction occurs. The material fractures at D (i.e. breaking point). The graph below shows the stress-strain curve for 4 different materials. Material which is good for making wires by stretching is

Who proved that blends of polyblend (plastic waste) and bitumen, when used to lay roads, enhanced the bitumen's water repellent properties and helped to increase road life?

Limestone is a naturally occuring form of calcium carbonate. It is used as building materials and also for manufacture of other building materials such as portland cement. It is used for the production of quickline and slaked lime which have wide applications in chemical, metallugical and construction industry. The pure CaCO_(3) , called precipitated calcium carbonate, is used extensively as filler, providing bulk to materials such as paint, plastics, printing links and rubber. it is also used in toothpastes, cosmetics and antacids. Quicklime and slaked lime are the cheapest and the most widely used bases for neutralising unwanted acids. Lime is used to neutralise acidic soils. An important application of quicklime is in air pollution control for the removal of SO_(2) in electric power plants. slaked lime is used in the manufature of other alkalis and bleacing powder, in sugar refinig, in tanning hide and in water softening. The substance not likely to contain CaCO_(3) is
