The effect of CuO addition on the phase composition of clinker and the Cu incorporation into the structure of clinker phases was monitored under laboratory conditions. Separate synthesized CuO-doped clinker phases as well as clinkers with different CuO content up to 4 wt.% were characterized by XRD, optical and electron microscopy with EDS analysis. It has been found that Cu tends to form a separate phase or a double oxide with Ca and incorporates in the clinker phases to a limited extent, except for C AF. With increasing CuO content in clinker, its phase composition changes, and the size of alite crystals increases.

Article Synopsis
- The study examines the difficulties of producing high-ferrite Portland cement clinker at low temperatures and investigates boron oxide as a potential stabilizing agent.
- Researchers found that at 1350 °C, the HFPC clinker suffers from severe pulverization due to a metastable phase, prompting the exploration of various stabilizers.
- While multiple agents showed promise, boron oxide emerged as the best option, with a maximum recommended content of 1% to avoid destabilization that impacts early strength development, highlighting a pathway to lower energy use and emissions in cement production.

This article presents research on the effectiveness of utilizing asbestos waste, particularly chrysotile asbestos, in the production of Portland cement. The study aimed to evaluate the feasibility of transforming asbestos cement (Eternit) through thermal treatment and its enrichment with mineral additives, enabling its integration into the clinker synthesis process. Differences in the physicochemical properties of types of cement produced from conventional raw materials and those manufactured using asbestos waste were analyzed.

Article Synopsis
- The study explores how the size of binder particles and the use of chemical additives affect the early strength and stiffness of eco-friendly mortars made with low clinker content and mixed cements that include high amounts of slag and limestone.
- By adjusting the particle size of the slag and using nano-granular C-S-H seeds, researchers found notable improvements in compressive strength—up to 162% in the first 24 hours—and rapid hydration effects within just 6 hours of mixing.
- The findings suggest that optimizing particle size and increasing C-S-H admixture levels enhance early mortar strength, allowing for a reduced use of clinker while still achieving a strong binder performance.
Effects of Fineness and Morphology of Quartz in Siliceous Limestone on the Calcination Process and Quality of Cement Clinker.

With the increasing depletion of high-quality raw materials, siliceous limestone, sandstone and other hard-to-burn raw materials containing crystalline SiO are gradually being used to produce clinker. This study investigates the influence of the quartz content and particle size in siliceous limestone on the calcination process and the resultant quality of cement clinker. Two different siliceous limestones were grinded to different fineness, and calcinated with some other materials.
