1. Green Reactive Powder Concrete
with Cement and Sand Replacement
using Fly Ash

2.  Abstract
 RPC is a type of concrete known for its very high compressive strength, exceeding that of regular
concrete.
 This project aims to develop RPC using a combination of cement, silica fume, superplasticizer, and steel
fibers.
 To assess the performance of the RPC, experiments will be conducted to measure its compressive
strength, tensile strength, and flexural strength.
 Fly ash, a byproduct of burning coal, will be used to partially replace cement in the RPC mix at various
ratios (3%, 6%, 9%, 12%, and 15%). This is done to improve the binding properties of RPC while making
it more eco-friendly and economical. It's also expected to further enhance the strength of the RPC.
