On 27 January 2016, a press conference been held regarding to the harvesting of silver prize in Pencipta15 exhibiton by Building Technology Postgraduate research students with their exhibited products -- cementless concrete. The research project is leaded by Dr Cheah Chee Ban. Acoording to Dr Cheah, cementless concrete, a concrete without using cement as main binder, otherwise, industrial by-product such as PFA (Pulverised Fuel Ash), HCWA(High Calcium Wood Ash) and GGBS (Ground Granulated Blast Furnace Slag) are been used as main binder.
