Cyclic bending behavior of pre‐cracked thin‐walled elements in high performance fiber reinforced concrete

open access: yesStructural Concrete, EarlyView.
Abstract High‐performance fiber reinforced concrete (HPFRC) is increasingly being adopted for thin elements, such as façade panels, due to its outstanding mechanical properties and attractive finishes. These elements endure cyclic loads during their service life, impacting material properties and potentially leading to fatigue failures, particularly in

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

open access: yesStructural Concrete, EarlyView.
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 ...

A Laboratory Investigation of the Effectiveness of Different Acids in Removing Mineral Trioxide Aggregate From Simulated Root Canals

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The aim was to compare the effectiveness of acids in removing MTA from root canals. Fifty acrylic blocks were filled with MTA and divided into groups – 10% hydrochloric acid; 10% citric acid; 2% acetic acid; 2% carbonic acid and 20% tartaric acid. MTA was removed with the acids, plus ultrasonic tips and rotary files.

Effect of high surface area alumina platelets on squeeze flow properties of geopolymer pastes

open access: yesInternational Journal of Applied Ceramic Technology, EarlyView.
Abstract Geopolymers are alkali‐activated inorganic polymers emerging as a leading alternative to ordinary Portland cement that have also garnered significant interest for additive manufacturing, particularly in refractory applications. Reinforcing geopolymers with alumina platelets enhances their mechanical strength and thermal stability, making them ...

Influence of wet foam incorporation on the pore structure and properties of metakaolin‐based porous geopolymers

open access: yesInternational Journal of Applied Ceramic Technology, EarlyView.
Abstract Lightweight geopolymers are well‐suited for construction applications, including thermal and acoustic insulation panels and fire‐resistant barriers. Their porous microstructure can be tailored by incorporating gas bubbles into the fresh ceramic mixture.
