The given diagram shows the process of cement production and then how this cement is used for concrete production. As is observed from the graph, cement production involves some complex processes and concrete production is done using the water, cement and sand in a concrete mixer.
The first diagram depicts that, to produce cement first the limestone and clay are crushed and the produced powder from this is passed through a mixer. The power is then passed via a rotating heater where heat is supplied constantly and this process creates the raw cement materials which is passed on a grinder machine to finally produce the cement. The cement is then packed and marketed for sell.
The second diagram presents how the concrete is produced for housing and building work. In the first stage, 15% cement, 10% water, 25% sand and 50% small stones are mixed in a concrete mixer machine and the machine rotates fast to have the ingredients mixed together to create the concrete.
Over the last century, our cities faced unprecedented growth of traffic congestion and as result of this we encounter a litany of environmental pollutions. Some experts believe that a rising cost of petrol is the best way to tackle these problems. I firmly believe that there is a defensible basis for this argument. In this essay some another possible solutions will be elaborated.
The proponents of this view claim that recent studies have shown that due to increasing the price of petrol, the using of this energy has dramatically decreased. As result of this, the wide demand of petrol has slumped. The key point to justify this attitude could be illustrated by a tangible example. Our country “Iran” has high reputation about having oil resources. Consequently, the price of the petrol was not justified by comparison with another country. To cut a long story short, after applying this idea in cities, the evidence has shown most of the people turn to some Alternatives instead of use private car. For example, by the time went on, the rising price of petrol has caused majority the people use much more public transportation rather than the past.
Alternatively, there are other possible solutions to address this issue. First and foremost, the governments should give special care to renewable energy such as: water, wind, solar energy and etc. Also they should encourage people to use public transportation such as: electric tram, metro, bus and etc. Last but not least, we should own up to the fact that we need cultural reconstruction about true understanding of energy crisis in our planet.
In conclusion, from what has been discus above, increasing the price of petrol can be effective factor to reduce consumption of this energy, at least in my country. Serious measures should be taken by government and individuals as duty for solving these problems. Also government must assume responsibility, stop passing the bulk and settle down the effective laws for control this issue. Finally, it is absolutely imperative we should not try to be wise after the events.
