Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...

Alkali-silica reaction in waterglass-activated slag mortars incorporating fly ash and metakaolin

, 2018
Mitigation of alkali-silica reaction (ASR) in concrete is essential for durable and sustainable constructions. In conventional Portland cement-based concrete, alumina-rich supplementary cementitious materials such as low-calcium fly ash and metakaolin ...

Influence of Processing Variables on the Hydrothermal Synthesis of Zeolite–Geopolymer Aggregates from Kaolin

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT This study addresses the influence of key processing variables on the hydrothermal alkaline treatment of low‐temperature fired kaolin‐aggregates for the development of zeopolymers (zeolite–geopolymer composites). Parameters such as hydrothermal treatment temperature (90 and 150°C), reactor volume (250 and 500 mL), liquid‐to‐solid (L/S) ratio ...

Durability of mortars modified with metakaolin [PDF]

Cement and Concrete Research, 2003
Abstract Results of an investigation to determine the effects of metakaolin additions on transport properties of mortars are reported. Comparisons are made to ordinary Portland cement (OPC) to determine the influence of addition and replacement percentage. Cement is replaced on a mass basis of 5–20% for metakaolin.

Development of Sustainable Paver Block to Suit Very Heavy Traffic Conditions Using Cassava Peel Ash

Engineering Reports, Volume 8, Issue 5, May 2026.
Sustainable paver blocks were developed using cassava peel ash and silane‐treated glass fibers. The optimized mix achieved superior strength, durability, and impact resistance, meeting IS 15658:2006 standards for heavy traffic. This eco‐friendly approach highlights an effective use of agro‐waste and fiber reinforcement for sustainable infrastructure ...
