Hanil Cement succeeded in developing and test-depositing the “CO₂ Injection Floor Mortar” for the first time in Korea.

CCUS (carbon collection, utilization, and storage) technology containing CO₂ in the mortar was applied to contribute carbon neutrality. This mortar will be deposited in real apartments with Lotte E&C in September.

Hanil Cement deposited “Remitar FS150” that injected CO₂ in a test unit within the Hanil Cement Gongju plant on Aug. 7.

 It uses a method of injecting 0.4kg of CO₂ for every m3 of mortar. Injecting CO₂ in the mortar increases the cement density during the curing process, allowing it to maintain identical strength even when reducing cement use by about 3%.

Hanil Cement explains that injecting it into all floor mortars sold annually can save up to 50 thousand tons of CO₂ including the effects of reduced cement use. This is the same amount of CO₂ emitted annually by about 16 thousand automobiles that drive 35km every day.

Hanil Cement has already secured automatic depositing technology for CO₂ injection floor mortars. A CO₂ quantitative injection device for mortars was developed and patented, where a portable silo equipped with this device can be used to deposit in multi-unit houses such as apartments. Portable silos refer to equipment that automatically mixes mortar and water and transports it to high floors using a hose.

“It is significant we can contribute to becoming carbon-neutral by applying CCUS technology in floor remitar products for the first time in Korea. We will continue to differentiate the quality of our remitar in the future,” said Director O Hae-geun of the Hanil Cement Technology Research Lab. 

On the other hand, Hanil Cement is carrying out the national research task of “Developing in-situ carbonization technology utilizing cement industry-generated CO₂” through industry-academe-research cooperation supported by the KETEP under the Ministry of Trade, Industry, and Energy. Eugene Corporation, Lotte E&C, Korea Institute of Limestone and Advanced Materials, Korea Institute of Ceramic Engineering & Technology, Korea Conformity Laboratories, etc. are participating in the task.
