This study comparably assessed the pozzolanic effect of silica fume (SF) and ground rice husk ash (RHA) as supplementary cementing materials on the properties of blended cement pastes and concretes. A commonly commercial silica fume (SF) and locally-produced rice husk ash (RHA) samples with two finenesses (one with larger size than cement and the other with smaller size than cement) were used i...

This research provides a characterization of ancient Roman mortars from “Villa del Capo di Sorrento” (commonly known as Pollio Felice” or “Bagni della Regina Giovanna”). A deepened analysis cementitious binding matrix and aggregates was conducted with the aims determining possible sources raw materials mix recipe, to evaluate minerogenetic secondary processes. Twenty samples taken Villa were in...

Mitigation of greenhouse gas emissions is becoming a significant factor in all industries. Cement manufacturing one the industries responsible for emissions, specifically carbon dioxide emissions. Pozzolanic materials have long been used as cement additives due to pozzolanic reaction that occurs when hydrated and formation cementitious material similar cement. In this study, shale, which common...

INTRODUCTION The purpose of this synthesis of available information was to provide the Texas Department of Transportation (TxDOT) with a concise document on the state of the practice regarding the use of kiln dusts for stabilization of subgrade soils or granular base materials in highway pavements. This document should assist TxDOT in making decisions related to allowing the use of kiln dusts a...

The utilization of many industrial byproducts in the construction industry is now well-developed as it helps in improving the sustainability in two ways. First, reuse of the materials which otherwise will burden the environment and will be occupying scarce land resource. Second, it minimizes the degradation of land and the environment as a result of comparatively less digging. Quantities of was...
