Alumosilicate ceramic proppants based on natural refractory raw materials [PDF]
The sintering-strengthening effect of the additions of the highly ferrous bauxite (with Fe[2]O[3] content of 20-25 % in the calcined state) in the compositions with refractory clays was established.

Sustainable cement production: minimizing CO2 by optimizing efficiency with LC3
LC3 (limestone calcined clay cement) is an innovative cement formulation that combines limestone and calcined clay. It was developed to address the environmental impact of traditional Portland cement production, which is associated with high carbon ...

Recycling of calcined clay as an alternative precursor in geopolymers: A study of durability
The alkali-activated materials have properties like commonly used cementitious materials, however, it does not have burning steps at high temperatures that emit large amounts of CO2 into the atmosphere.

Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping
ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

A Termite‐Inspired Alternative to Cement
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,
