The number of variables that national construction companies have to deal with on site is gradually increasing and they are suffering from headaches. However, it is impossible to wait for the environment to change. Sampyo Group, a leading company in basic building materials, has garnered a great response from construction companies by launching new specialty concrete products that overcome these barriers with technology. By changing only the concrete, the construction period was shortened, construction was possible even in sub-zero conditions, and construction noise and human accidents were greatly reduced. Sampyo’s specialty concrete products have recently been installed at construction sites such as Samsung Electronics’ Pyeongtaek Semiconductor Plant, Hyundai E&C and Daewoo E&C, with sales increasing 2.5 times over the previous year. Sales increased even in the event of a strike due to various regulations, union disputes, and abnormal weather. As the downstream construction industry plummets, ready-mix concrete shipments domestically have been on a downhill path since 2017. Lee Seok-hong, vice president of Sampyo Industries, said: “The sales target of this year is three times greater than last year. “
Asia’s best technology for ‘freezing ready-mix concrete’ … The pouring period is also shortened to a third.
Since the 52-hour weekly work system has been expanded to companies with 50 or more employees this year, most construction sites are fighting against time to avoid delays due to reduced working hours. Sampyo released the number of matches with ‘quick hardening concrete’. In the normal process of frame construction, after the reinforcing bars are laid and the formwork is installed, the concrete (remicon) in an unhardened state is poured into the concrete. Ready-mixed concrete hardens into concrete through a “curing” process that gradually increases its strength while generating heat. Typically, general ready-mix concrete requires a curing period of 2-3 days, but Sampyo’s ‘Blue Corn Speed’ specialty concrete sets in 18 hours. According to Sampyo, it usually takes 8 to 9 days to complete the frame construction of an apartment floor using ordinary concrete. However, with this product, it only takes 1 to 2 days and comes down to a third level. This product, developed by Sampyo in 2018 and first marketed in Korea in 2019, was supplied to construction sites of large construction companies such as Hyundai E&C, Daewoo E&C and POSCO E&C last year, and the sales volume doubled with Over the previous year. .
Under normal subzero weather conditions, ready-mix concrete does not harden and moisture inside freezes, making ready-mix concrete impossible to pour. However, if the temperature of ready-mixed concrete is artificially increased by burning lignite, field work is possible, but workers suffocate accidents due to burning lignite, and air pollution problems persist. However, even last winter, which saw a ‘record cold snap’, Sampyo’s special concrete was sold as if it were a wing on site. This is because construction was able to continue without interruption thanks to ‘Blue Corn Winter’, which does not freeze even at -10 degrees Celsius. Last year’s sales volume was 2.5 times higher than the previous year. As a result, construction companies say that the speed of the process has improved by about 20-30% compared to the previous year, and that they were able to save tens of thousands of won in costs by building an apartment. This product is the only ready-mix concrete in Korea that can be used on construction sites even in sub-zero weather. In terms of related technologies, it is one of the best in Asia, Sampyo explained. Vice President Lee said, “Last winter, market demand was so high that there wasn’t enough sales force to respond to it.”

Another risk from urban construction sites is noise complaints from neighboring residential areas. Most complaints are caused by vibrators making a loud noise (90㏈) when pouring ready-mixed concrete. The vibrator is a device that presses and fills the concrete so that no air bubbles are left due to the internal concrete structure when pouring ready-mixed concrete. However, Sampyo’s ‘Blue Corn Self’ is a special concrete that does not require a vibrator, reducing noise on site by approximately 20%. This is because this product has high flowability and fills the gap on its own, even between dense rebar at 3cm intervals that ordinary ready-mixed concrete cannot enter. Therefore, the more complex and precise the structure of the building, the more useful it will be. When placing ready-mix concrete, it is not necessary to compact it, so labor costs can be saved.
It is known that a considerable quantity of this product was also supplied to Samsung Electronics’ semiconductor plant in Pyeongtaek. Sampyo owns five proprietary technologies related to special concrete, such as Bluecorn Speed, Winter and Self. All of them are the first products that Sampyo commercialized last year. In addition, the special concrete ‘Blue Corn Floor’ was also popular, which solved the problem of frequent cracks in the floor of the apartment’s underground parking lot. According to Sampyo, the sales volume exceeded 10 times the previous year as demand from large construction companies building luxury apartments increased due to frequent complaints from apartment residents.
Sampyo’s development of special concrete is due to a decline in the construction industry and factors that deteriorate profitability are increasing, such as an increase in transportation costs due to a strike by truck owners and expansion of the system. 52-hour workweek. Jeong Do-won, president of Sampyo Group, has invested 40 billion won in the past five years just to develop special concrete technology, bracing for losses in order to overcome these difficulties. It was also President Chung’s decision to hire Vice President Lee, former Chief Technology Officer (CTO) of Hyundai E&C in 2019. The price of the four types of specialty concrete sold by Sampyo is 1.3 to 1.5 times higher than the price. of general products, but sales are increasing rapidly, emerging as a new growth engine. Vice President Lee said, “Expected sales of specialty concrete this year will be in the tens of billions of won, but in the long term, we plan to increase them to 10-20% of Sampyo Group’s annual sales (3 trillion won). “.

The future technology that Sampyo is striving to develop is ultra-high-strength concrete (UHPC), which is ten times stronger than general concrete. Vice President Lee explained, “The force that not even bunker-busting missiles can penetrate (150 ㎫)” and “It is a technology that saves the environment as a result because it is not necessary to make the walls thick to achieve high strength.”
