Abstract

For the preparation of modern cement and concrete, supplementary cementitious materials (SCM) have become essential ingredients. The technical, economic and environmental advantages of using SCM have become unquestionable. The main technical reasons for their use are the improvement of the workability of fresh concrete and durability of hardened concrete. Actually, SCM affect almost all concrete properties, while environmental and economic reasons may be more significant than technical reasons. These ingredients can reduce the amount of Portland cement used in cement composites, resulting in economic and environmental benefits. In addition, many of the SCM are industrial by-products, which can otherwise be considered as waste. This paper presents a literature review of the present knowledge on the impact of natural zeolite, waste construction brick and waste container glass on physical, chemical and mechanical properties of Portland cement as the most commonly used cement in the world.

Highlights

The cement industry plays a very important role in the global economy, especially that of Portland cement as the most used building material [1]
Cement industry is responsible for 8 % of CO2 emissions worldwide [4]
From the results presented in this review paper, the following conclusions can be drawn:

Summary

Introduction

The cement industry plays a very important role in the global economy, especially that of Portland cement as the most used building material [1]. Since large amounts of raw materials are needed during the clinker production process to produce billions of tons of cement worldwide, large quantities of CO2 are released. The price of energy is growing steadily from day to day as sources of fossil fuels are being exhausted. This leaves an indelible mark on the cement industry and the price of cement. Waste from demolition of buildings and the growing need for fillers as additives to cement irreversibly affect the environment and represent concrete as a material that affects negatively sustainable development of the society at large [7]
