DEVELOPMENT OF SUSTAINABLE CEMENTITIOUS MATERIALS

Portland cement (PC) concrete is the most popular and widely used building material because its raw materials are available over the world. This paper introduces two types of sustainable cementitious composites, geopolymer and magnesium phosphate cement. Compared with PC, these two cements possess some common and individual characteristics. The paper presents recent developments of these two materials. Investigation has shown that they have superior properties compared to PC such as high early strength, excellent volume stability, better durability, good fire resistance, and easy manufacture process.
