Utilization of Cordia Africana wood sawdust ash as partial cement replacement in C 25 concrete

open access: yesCleaner Materials, 2021
Partial replacements are being explored for cement in concrete to reduce the environmental negative effect of their use. This study aimed at investigating the effect of Cordia Africana sawdust ash (SDA) as a partial replacement of cement, on the fresh ...

Physical characterization methods for supplementary cementitious materials [PDF]

open access: yesMaterials and Structures, 2014
The main supplementary cementitious materials (SCMs) that are used today are industrial by-products. In most cases the quality of these materials cannot be controlled during their production, resulting in materials with varied characteristics. The adequate physical characterization of SCMs is important to better predict their performance and optimize ...

Reutilization of Ceramic Waste as Supplementary Cementitious Material

open access: yes, 2023
The production of Portland cement (PC) has the highest environmental impact among the different components of concrete. Also, although ceramic prod-ucts are consumed worldwide and constitute a significant fraction of construction and demolition waste, significant amounts of ceramic waste (BCW) are simply landfilled or used as road sub-bases.

Calcium oxychloride formation in pastes containing supplementary cementitious materials: Thoughts on the role of cement and supplementary cementitious materials reactivity

open access: yesRILEM Technical Letters, 2016
Over the last decade many concrete pavements in North America have begun to show excessive damage at the joints. This damage appears to be due to two primary causes: classic freeze-thaw damage due to local saturation caused by the pooling of water at the

State-of-the-art-review on rice husk ash: A supplementary cementitious material in concrete

open access: yesJournal of King Saud University: Engineering Sciences, 2021
Rice husk ash (RHA) is a good supplementary cementitious material for concrete production, as it requires low energy and emits negligible greenhouse gas during processing and service life as well as it shows high pozzolanic reactivity.
