Chemical and Microstructural Evolution of Cement Pastes with Additives and SCMs During the First 24 h

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Early‐age chemical evolution governs the development of hydrate assemblages and microstructure in cementitious systems, especially when additives and supplementary cementitious materials are incorporated. This study investigates the first 24 h of hydration in Portland cement pastes modified with selected additives and supplementary ...

Calculation of Chloride Penetration Profile in Concrete Structures

International Journal of Electrochemical Science, 2013
This article shows the development and implementation of a software that calculate the chloride penetration profile in concrete obtained using traditional Portland cements and cementitious mixtures from the addition of pozzolanic materials such as silica

A Termite‐Inspired Alternative to Cement

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Microstructure and Performance Optimization of Barley Husk Ash–Blended Mortars: A Sustainable Approach to Cement Substitution

Engineering Reports, Volume 8, Issue 4, April 2026.
Barley husk ash (BHA), an agricultural byproduct rich in pozzolanic oxides, was optimized as a sustainable cement substitute. Statistical modeling and experimental validation confirmed 22.75% BHA as the optimal replacement, enhancing mechanical and durability performance while advancing eco‐efficient construction practices.

Low‐Carbon Composite Cement Mortar Incorporating Local Raw Materials as SCMs: Performance and Life Cycle Analysis

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
Overview of the experimental plan. ABSTRACT Performance and life cycle analysis of composite cement mortars developed using local conventional (blast furnace slag and fly ash) and novel non‐conventional (stone wool, glass wool, calcined Finnish clay, volcanic pozzolan Iceland, and ladle slag) raw materials as supplementary cementitious materials (SCMs)

Mix Proportion of Fly Ash Concrete Based on the Strength Contribution Ratio

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT This study aims to expand the use of fly ash concrete (FAC). Based on an experimental investigation of k values or the contribution of FA addition to the strength of ordinary Portland cement or Portland blast‐furnace slag cement type B, we propose and validate an environmentally friendly mix design for FAC.

Sugarcane bagasse and rice husk ash pozzolans: Cement strength and corrosion effects when using saltwater

Current Research in Green and Sustainable Chemistry, 2020
The production of ordinary Portland cement (OPC) contributes to the release of harmful greenhouse gases. In an effort to reduce these emissions, this study explores biomass materials to evaluate their use as partial replacements for ordinary Portland ...

Comparative Analysis of Selected Physicochemical Properties of Pozzolan Portland and MTA-Based Cements [PDF]

International Scholarly Research Notices, 2014
Physicochemical properties of pozzolan Portland cement were compared to ProRoot MTA and MTA BIO. To test the pH, the samples were immersed in distilled water for different periods of time. After the pH analysis, the sample was retained in the plastic recipient, and the electrical conductivity of the solution was measured. The solubility and radiopacity

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...
