Opis

This book discusses the detailed concepts of concrete and its development with pros and cons. Besides, the significance of various industrial wastes as partial replacements with concrete ingredients such as cement and aggregates are discussed. The creation of cement contributes to around 7% of carbon emissions into the atmosphere leading to greenhouse effect and global warming. Similarly, the wastes generated from various industries such as thermal, steel, ceramic, marble, paper and etc. shows the impact on atmosphere and leads to air pollution and land pollution. Thus, it is essential to focus on these wastes to use them in a profitable manner without compromising the current needs. This book discusses a few examples on studies of using various industry wastes as partial replacement of cement in concrete​
