Predicting the Tensile and Unconfined Compressive Strength of MICP-Treated Sands

Journal of Geotechnical and Geoenvironmental Engineering
Microbially Induced Carbonate Precipitation MICP has been studied over the last 20 years as a promising bio-mediated alternative to enhance soil mechanical performance. Multiple studies have investigated different MICP treatment techniques and their application to various coarse-grained soils.

PREDICTION OF UNCONFINED COMPRESSIVE STRENGTH OF ROCKS: A REVIEW PAPER

Jurnal Teknologi, 2015
Unconfined compressive strength (UCS) of rocks is a crucial parameter in designing geotechnical structures. Owing to difficulties in obtaining proper samples for UCS test as well as the point that conducting UCS is relatively expensive, the use of indirect methods for UCS estimation has drawn considerable attentions.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Impact of Nano-SiO₂ on the Compressive Strength of Geopolymer-Solidified Expansive Soil

Buildings
Expansive soil is widely distributed and often needs to be improved for engineering and construction needs. Using blast furnace slag and fly ash as precursors and NaOH as an alkali activator, a geopolymer was prepared to solidify expansive soil, and the ...

Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

Advanced Materials, Volume 38, Issue 47, 21 August 2026.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, Volume 14, Issue 8, Page 3697-3725, August 2026.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Tides of the Midland: From Groundwater Into the River

Hydrological Processes, Volume 40, Issue 8, August 2026.
Tides in a river that is NOT influenced by the ocean, is not in the coastal area and is more than 300 m above sea level are caused by groundwater tides. As the phases of the Moon change, the amplitudes of the streamwater oscillations vary synchronously with those of gravitational acceleration.
