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

Journal 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.

Wet-Treated MSWI Fly Ash Used as Supplementary Cementitious Material

Advances in Materials Science and Engineering, 2015
Municipal solid waste incineration (MSWI) is a common technique in treatment of domestic waste. This technique annually produces approximately 25 Mt solid residues (i.e., bottom and fly ash) worldwide which is also a major issue in current research.

Overview of clay as supplementary cementitious material [PDF]

5th Symposium on Doctoral Studies in Civil Engineering, 2019
Locally available materials, like clays, present a potential to meet the growing concrete demand and to produce more sustainable material. This paper reviews the behaviour of common clay minerals (kaolinite, illite and montmorillonite) giving an insight into the complexity of clay soils that usually appear as mixtures of minerals and impurities.

Ladle Furnace Slag as a Partial Cement Substitute in Mortars with Water-Retaining Admixtures [PDF]

Materials Research
Ladle furnace slag (LFS) is a byproduct from steel refining with high calcium oxides and hydroxides contents, making it viable as a supplementary cementitious material (SCM), enhancing microstructure and mechanical properties, particularly in mortars ...

Exploring the applicability of thermodynamic modeling to predict the degree of reaction of supplementary cementitious materials in Portland cements

Developments in the Built Environment, 2023
A reaction degree of supplementary cementitious materials (SCMs) in hydrated Portland cement is an important factor that enables prediction of the performance of concrete, while conventional methods for estimating the degree of reaction of SCMs are ...

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
