Current Status and Future Trends of the Cement Products Industry

Cement products are industrial goods made by deeply processing cement-based binders. Thanks to their ability to be molded into desired shapes and sizes according to design specifications, they boast excellent physical and mechanical properties, low energy consumption, corrosion resistance, long service life, minimal maintenance requirements, and significant savings in metals and other raw materials. As a result, these products have found extremely wide application in urban and rural areas, industrial and mining enterprises, agricultural water conservancy projects, as well as in infrastructure construction related to energy, transportation, communications, and municipal services across China, yielding remarkable social and economic benefits. To meet the growing demand for concrete and cement products driven by the rapid development of the national economy and improving living standards, through technological advancement and innovation, and with concerted efforts from the entire industry, not only has the pre-mixed concrete sector achieved substantial growth, but also notable progress has been made in the development of new products. According to incomplete statistics, there are currently about 5,000 pre-mixed concrete stations (plants) nationwide, with a designed annual production capacity reaching 1 billion cubic meters and an actual annual output of 600 million cubic meters. In cities such as Beijing, Shanghai, Guangzhou, Shenyang, and Dalian, the volume of pre-mixed concrete used has already approached levels seen in economically developed countries.

[Internal Cement Reference] On January 9, a cement enterprise in Hebei experienced a severe collapse of the sidewall during a warehouse-clearing operation, resulting in a major safety accident that claimed six lives. This incident has promptly brought the issue of safety in warehouse-clearing operations at cement enterprises into sharp focus. According to information obtained by Internal Cement Reference, in recent years, there have been numerous accidents involving casualties caused by warehouse-clearing activities in China’s cement industry. For example: An accident at a cement company in Yakeshi: On January 21, 2008, a worker was cleaning the walls of a cement silo when he fell and was buried under cement. Three other workers who attempted to rescue him were also buried. After being pulled out, all four victims died despite resuscitation efforts. An accident at a cement plant in Liangping: On October 10, 2008, several workers were clearing material inside a clinker silo when a large chunk of cement weighing about two tons collapsed, killing two workers and injuring one. A fatal fall accident at a cement workshop in Xinjiang: On the afternoon of July 18, 2008, a batching operator from the company’s cement workshop entered a cement blending silo alone to address a problem with the smooth flow of blended materials. Unfortunately, he accidentally fell into a steel silo. After more than 40 minutes of rescue efforts by on-site personnel, he was pulled out and taken to the hospital, where he was pronounced dead. A fatal accident at a homogenization silo in a Taishan factory: On November 26, 2008, the shift supervisor of the kiln section led workers to clean Silo No. 6 for wollastonite. They used gas cutting to open the discharge port and manhole, then removed the discharge valve. The first worker who descended into the silo was confirmed dead by 120 emergency medical staff. An accident at a cement plant in Fuzhou involving the cleanup of a slag silo: On May 4, 2009, five workers cleaning waste slag from the inner wall of a slag silo were buried by collapsing slag and suffocated to death. An accident at a cement plant in Chaohu involving the unclogging of a slag discharge chute: On June 27, 2009, Ding, a member of the slag-drying team, attempted to clear a blocked discharge opening at the bottom of the slag discharge chute (discharge funnel). His attempt failed, so Ding went up to the top of the silo and began manually clearing the blockage from above. Since no one was supervising him on site, Ding was pushed into the silo along with the slag by a bulldozer. It wasn’t until noon that Ding was found—but he had already died of asphyxiation. ... ... The tragedies caused by these various safety accidents are still vividly remembered, yet they consistently fail to prompt serious attention from major cement enterprises and subcontractors responsible for warehouse-clearing operations, leading to repeated safety incidents. So, how can cement enterprises carry out warehouse-clearing operations safely? To address this question, Internal Cement Reference conducted an in-depth discussion with Deng Youquan, the head of Guangzhou Desler Industrial Equipment Co., Ltd. (hereinafter referred to as “Desler”), a well-known domestic company specializing in research and development of warehouse-clearing equipment. According to Mr. Deng Youquan, Technical Manager at Desler, due to various factors, powdery materials inside silos tend to stick to the walls and accumulate at the bottom, reducing the silo’s capacity and causing difficulties—or even complete blockages—in discharging materials. To ensure continuous production, enterprises must conduct regular, scheduled warehouse-clearing operations. However, currently, many problems exist in China’s cement industry regarding these operations. First, many cement enterprises still rely on manual labor for warehouse-clearing, which inherently carries significant risks. Analysis of past safety accidents in the cement industry shows that warehouse-clearing operations are the single biggest cause of worker fatalities. Second, manual warehouse-clearing requires substantial labor input. Currently, the standard fee for warehouse-clearing services ranges from approximately 60,000 to 120,000 yuan per silo. As public awareness of safety increases, fewer workers are willing to enter silos for clearing, meaning labor costs will continue to rise year after year. Moreover, traditional manual warehouse-clearing is time-consuming. Cleaning a silo is a challenging and complex task. To ensure safety, manual clearing must be carried out from top to bottom, so the duration of clearing a single silo can take weeks or even months, depending on the amount of accumulated material. Recognizing the dangers posed by manual warehouse-clearing to both cement enterprises and workers, as well as the enormous costs involved, Desler has stepped up its efforts in researching and introducing advanced warehouse-clearing equipment. According to Mr. Deng Youquan, pneumatic warehouse-clearing equipment is already widely used abroad for clearing silos containing various materials—including cement, steel, energy, minerals, lime, and food—making it today’s most widely adopted, safest, and most efficient equipment for silo cleaning worldwide.

From January to August 2018, the cement manufacturing industry achieved profits of 96.3 billion yuan.

The NDRC website recently reported that, in the first three quarters of this year, national cement production reached 1,582.5 million tons, up 1% year-on-year, compared to a 0.5% decline in the same period last year. Commercial concrete production totaled 130.645 million cubic meters, an increase of 10.1%, with the growth rate rising by 0.9 percentage points over the previous year. Flat glass production amounted to 64.763 million weight boxes, up 0.4%, but the growth rate fell by 4.6 percentage points compared to the previous year. Compared with the previous month, prices of both cement and flat glass saw slight increases. In September, the average price of P.O 42.5 bulk cement across the national market was 434 yuan per ton, up 12 yuan per ton from the previous month—a rise of 2.8%. Year-on-year, the price increased by 98 yuan per ton, representing a 29.2% increase. The average ex-factory price of flat glass (raw sheet glass) was 67.1 yuan per weight box, up 0.7 yuan per weight box from the previous month—a rise of 1.1%. However, year-on-year, the price fell by 1 yuan per weight box, marking a 1.5% decrease. From January to August, the building materials industry achieved profits totaling 286.8 billion yuan, up 46.1% year-on-year. Among them, the cement manufacturing sector generated profits of 96.3 billion yuan, an increase of 1.5 times; the flat glass sector earned profits of 8.6 billion yuan, up 40.6%.
