Strength, Sulfate Resistance, and Microstructural Characteristics of Concrete With Partial Cement Replacement Using Eggshell Powder and Wheat Straw Ash

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
This study explores the partial replacement of ordinary Portland cement (OPC) with a composite of eggshell powder (ESP) and wheat straw ash (WSA) in C‐25 concrete, focusing on mechanical performance and durability. Cement was replaced with varying proportions of ESP and WSA, and the concrete mix was prepared following ACI guidelines.

Development of EPS light‐weight concrete for 3D printing

Structural Concrete, Volume 26, Issue 6, Page 7256-7268, December 2025.
Abstract This study investigates the feasibility of 3D printing lightweight concrete (LWC) incorporating expanded polystyrene (EPS) beads, with a focus on optimizing mechanical properties and flowability for 3D concrete printing (3DCP). The research addresses the need for printable, structurally viable lightweight materials by developing and testing ...

Polycarboxylate/nanosilica-modified quaternary cement formulations – enhancements and limitations [PDF]

Advances in Cement Research, 2018
The effect of polycarboxylate/nanosilica (nS) particles in quaternary cement formulations comprising Portland cement (PC), limestone powder (LS) and fly ash (FA) was investigated for the first time. The reference formulation contained 60% PC, 20% LS and 20% FA by mass of binder in an effort to minimise clinker and maximise the other constituents.

Concrete Pavement Mixture Design and Analysis (MDA): Evaluation of Foam Drainage Test to Measure Air Void Stability in Concrete [PDF]

, 2015
The stability of air bubbles in fresh concrete can have a profound influence of the potential durability of the system, because excessive losses during placement and consolidation can compromise the ability of the mixture to resist freezing and thawing ...

In Vitro Assessment of the Effects of Endodontic Sealers on Cell Viability, Adhesion, and Migration

Australian Endodontic Journal, Volume 51, Issue 3, Page 740-747, December 2025.
ABSTRACT This study aimed to evaluate the in vitro cytocompatibility and bioactivity of the newly launched calcium silicate‐based sealer BioRoot Flow, compared with other calcium silicate‐based sealers (AH Plus Bioceramic Sealer and BioRoot RCS) and the epoxy resin‐based AH Plus Jet.

Predicting air‐entraining in cement paste from the molecular attributes of nonionic surfactants with a multilayer method

Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Abstract The novelty of this study is to present a multilayer framework for predicting the air‐entrained porosity of cement paste based on the molecular characteristics of nonionic surfactants. Air‐entraining agents enhance concrete durability against freeze–thaw damage; however, their development is labor‐intensive and cost‐prohibitive.
