Indonesia looks to use steel slag waste in concrete

The Indonesian Ministry of Environment and Forestry is partnering the Ministry of Public Works to conduct research on using steel slag waste as an ingredient for asphalt concrete mix. It is claimed that the use of steel slag waste, though more expensive, will increase the strength of concrete by 400% compared to the use of limestone. Slag can also be used as sand blasting for paving block and painting ship docks. However steel slag is still categorised as toxic and hazardous waste.

Scientists develop cement-free concrete

A team at Kaunas University of Technology (KTU) in Lithuania is developing a method of producing concrete without cement.

The product uses industrial waste such as fly ash instead of cement and the KTU scientists claim it is as strong as traditional concrete, more resilient to damaging effects of acid, and more stable in cases of exposure to extreme heat and cold.

Aiming to reduce the concrete industry’s negative impact on the environment, KTU researchers have been investigating methods of substitutin
