Scrap glass is a solid waste from daily recycling. Most of the waste glass is sodium-lime-silicate glass which has, more or less, similar chemical compositions to clay, a raw material in cement manufacturing. Therefore, we utilize the solid waste in cement raw mix by replacing part of the clayey component. In this study, the effects of the glass in cement …

(57) Various examples related to portland cement manufacturing using municipal solid waste incineration (MSWI) ash are provided. In one example, a method includes providing a raw kiln feed including MSWI to a kiln, forming ash-amended clinker (ACK) by heating the raw kiln feed in the kiln, and preparing ash-amended cement (AAC) from the ACK.
Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller …
