Green options for anti-corrosion of high strength concrete incorporating ternary pozzolan materials

MATEC Web of Conferences, 2017
This paper applied the densified mixture design algorithm(DMDA) method by incorporating ternary pozzolans (fly ash, slag and silica fume; mix I and mix II) to design high strength concrete (HSC) mixtures with w/cm ratios from 0.24 to 0.30.

The workability, mechanical, and electrical properties of steel fiber‐reinforced SCC incorporating ultra‐fine copper slag as fine aggregate

Structural Concrete, Volume 26, Issue 6, Page 7571-7590, December 2025.
Abstract Ultra‐fine copper slag (CS), a byproduct of the copper industry, is al waste material that is produced in large volumes annually, and its disposal and management are a major environmental concern. Therefore, the utilization of CS in various sectors, especially in the production of construction and building materials, offers enormous potential ...

Evaluation of electric properties of cement mortars containing pozzolans

Materiales de Construccion, 2011
In this paper the evolution of the microstructure of Portland cement mortar is analyzed, by using electrical impedance measurements. Cement mortars are compared without and with two pozzolanic substitutions: spent fluid catalytic cracking catalyst (FCC ...

Monitoring the reduction in shrinkage cracking of mortars containing superabsorbent polymers [PDF]

, 2017
Ultra-high performance concrete (UHPC) is characterized by a low water-to-cement ratio, leading to improved durability and mechanical properties. However, the risk for autogenous shrinkage and cracking due to restrained shrinkage increases, which may ...

Sustainable infrastructure development through use of calcined excavated waste clay as a supplementary cementitious material [PDF]

, 2017
Major infrastructure development projects in London produce large quantities of London clay and use significant volumes of concrete. Portland cement (CEM I) in concrete is normally partially replaced by supplementary cementitious materials such as ground

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, Volume 12, Issue 42, November 13, 2025.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Performance of silicic pozzolans and Portland cements in their behavior in front of gypsum attack as determined by ASTM C 452-68

Materiales de Construccion, 2013
For this study, ASTM C 452-68 testing was conducted for two years on 54 POZC-silica fume (SF) or diatomites (D and N) (=Z pozzolans), were tested for 2 years, by ASTM C 452-68 method, having determined to their specimens their Vcl(=ΔL(%)/day) .

An artificial neural network approach to predict particle shape characteristics of clay brick powder under various milling conditions

Results in Materials
The prediction and monitoring of shape descriptors of pozzolans generated from ball milling processes remain today unattended by researchers. Since the particle shapes of pozzolans influence the performance of pozzolanic materials in cement-based ...
