Use of Fluorogypsum-Based Blends as Green Construction Materials

Introduction

This research aims to develop a concrete-like material for underwater construction applications by using fluorogypsum (FG, an industrial by-product of hydrofluoric acid production), class C fly ash, and type II Portland cement.
