Reactive Powder Concrete, an Innovative Collaboration between WIKA Beton and ITB Campus


The raw material for making concrete consists of three main components: Cement, water and aggregate. Now for the aggregate raw material itself, it comprises still two more components, namely fine and coarse aggregate. Coarse aggregate is gravel whilst fine aggregate is concrete sand.

However, since the end of 2017 WIKA Beton and the Bandung Institute of Technology have succeeded in creating a new innovation. The innovation is called Reactive Powder Concrete (RPC). 

Reactive Powder Concrete is an innovation whereby both aggregate raw materials are put together to make it more economical!
As explained above, if you need to make concrete, two aggregate components are needed, namely gravel and concrete sand. From the two aggregate components, came the idea to combine these two components. So you could say RPC is a concrete made from just one aggregate component. The aggregate used is also special, it consists of various micro-sized materials. 

The advantages of RPC   
Because it is made from a micro-material aggregate, concrete has homogeneity, compactness and high durability. RPC containing micro material, one of which is silica which is also able to react at higher temperatures in the manufacturing process, thus accelerating the increase in strong concrete pressures. With this range of advantages, RPC can be made with a smaller, thinner and optimal cross section. 

This collaboration shows that WIKA Beton cares about the successors of concrete industry
The creation of this RPC took not a short time. The research started in 2014.  It took approximately three years before this RPC was ready to be mass-produced.  The collaboration with ITB is a link-and-match or collaboration between academia and industry. As pioneer of the concrete industry in Indonesia, WIKA Beton synergizes production capabilities and concrete manufacturing technology for development in the field of science to be more advanced.
