Abstract

Infrastructure is the driving wheel of a country’s economic growth, one of which is Indonesia. Based on the Central Statistics Agency (BPS), infrastructure in the third quarter of 2021 grew by 3.84%. This infrastructure growth increases the use of cement so that it contributes to CO₂ emissions in the world by 5 – 7%. Indonesia is also faced with environmental problems, namely industrial waste that has not been managed optimally, including fly ash waste, glass waste, and granite waste. From these problems came the innovation of eco-friendly concrete that is quality and economical, which is called Ecompact Concrete. This concrete uses Grashka waste (Granite, Fly Ash and Glass) with a proportion of 50% crushed granite as a partial replacement for coarse aggregate, 3% glass powder and 5% fly ash as a partial replacement for cement. The advantage of Ecompact concrete is that it has a higher compressive strength than normal concrete, namely 23.35% at 7 days and 28.71% at 28 days. The price of Ecompact Concrete is 11.72% more economical than ordinary concrete. The application of Ecompact Concrete can also reduce the use of coarse aggregate by 50% and cement by 8%. With Ecompact Concrete, it is hoped that it can reduce the problem of CO₂ gas emissions produced by cement factories, reduce granite, glass and fly ash waste, and develop green infrastructure in realizing sustainable development in Indonesia.
