Recently, the president of a construction group said that cement could no longer be used in the construction of buildings!
The person listed the "three major crimes" of cement: high carbon emissions, unsafe and construction waste siege. Is the
truth really as he said? The answer is no!
On the issue of carbon emissions in the cement industry. The cement industry is known as a major carbon emitter in China, which is indeed "worthy of the name". In this regard, cement plants have long been aware of their own carbon emissions and have taken a number of measures to reduce carbon emissions and carbon neutralization, and have made a lot of achievements. Such as carbon capture and utilization, renewable fuels and so on.
For example, in view of the carbon dioxide produced in the production process of the cement industry, in order to fulfill the social responsibility of large state-owned enterprises, Conch Group has taken active and bold actions to carry out carbon capture and purification work in cement kilns. In October 2018, the world's first cement kiln flue gas carbon dioxide capture and purification environmental protection demonstration project built by Conch was successfully put into operation. The successful completion of the demonstration line is the first in the world cement industry to realize the industrialization of carbon capture and utilization, which has far-reaching demonstration and leading significance for promoting energy saving and emission reduction in China and even in the world cement industry.
In addition, in recent years, many cement enterprises, such as Conch Cement , Tianshan Stock, Huaxin Cement and Huarun Cement, are accelerating the promotion of non-fossil energy alternative fuels and the implementation of green energy structure. Recently, the optimized Arundo donax test-tube seedlings jointly cultivated by China Resources Cement and Aerospace Shenzhou Biotechnology Group were successfully returned by Shenzhou 16 manned spacecraft through space mutagenesis. It is reported that the combustion rate of space Arundo donax as biomass fuel is equivalent to that of bituminous coal, which opens up a new way for carbon reduction in cement industry. The
other two points of insecurity and construction waste are simply nonsense.
First of all, let's talk about the safety of cement. There are many long-lived buildings throughout the ages, including cement buildings with a history of more than 100 years. As for the prevention of earthquakes, there are relevant construction norms in the construction industry, which have nothing to do with cement. It is even more absurd to
say that buildings made of cement will be unsafe if they fall down. Steel will also hurt people if it falls down. Is it impossible to use steel? If a car is going to kill someone, is it impossible to drive a car?
As for construction waste, at present, the recycling of construction waste has been very mature and is on the rise. It is worth mentioning that cement can turn a large amount of solid waste into treasure in the production process!
Therefore, to sum up, the "three major crimes" of cement mentioned by the above-mentioned people are not established, but are nonsense.
At present, cement is the most economical and practical building material, and no product can replace cement.
Looking up at the tall buildings scattered all over the place, overlooking the crisscross roads and paths, these are all "masterpieces" made of cement. It can be said that cement has witnessed the development of the world economy and is also an important cornerstone of building a modern civilization in the world.
What's more, today's cement plants are no longer what they used to be, and garden-style intelligent cement plants are entering the public's vision. At the same time, in recent years, the co-disposal of solid hazardous waste in cement kilns has developed vigorously, creating conditions for the cement industry to build a better environment. Building a waste-free city and making cement plants a companion industry of the city has gradually become the consensus of more and more cement enterprises.
