Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes

Structural Concrete, EarlyView.
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...

Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

Structural Concrete, EarlyView.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

EFFECT OF ADDING CEMENT AND SILICA FUME WITH CEMENT ON COMPACTION PROPERTIES AND SHEAR STRENGTH OF CLAYEY SOIL

Al-Qadisiyah Journal for Engineering Science, 2009
This paper describes a study on the effect of adding cement and silica fume with cement on the engineering properties (Compaction and Shear strength) of the clayey soil. Inorganic clay with low plasticity was used in this study as a natural soil.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.
