Pumping Lightweight Aggregate Concrete

Journal of the Society of Materials Science, Japan, 1969
In Japan the pumping of concrete is generally in practice in the building projects to save labor because of manpower shortage in the country. But there are some problems in pumping the concrete, especially of the lightweight aggregate concrete.It is the aim of this report to present information on the above mentioned problems which has been obtained ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Evaluation of the properties of lightweight concrete using periwinkle shells as a partial replacement for coarse aggregate

Journal of Applied Sciences and Environmental Management, 2016
The properties of lightweight concrete, such as aggregate impact value, aggregate crushing value and compressive strength were assessed utilizing periwinkle shell (PWS) as partial replacement for coarse aggregate.

Three‐dimensional Antimony Sulfide Based Flat Optics

Advanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

Structural Lightweight Concrete Containing Recycled Lightweight Concrete Aggregate

KSCE Journal of Civil Engineering, 2018
In this paper, Structural Lightweight Concrete (SLC) containing Recycled Lightweight Aggregate (RLA) is described. Damaged lightweight concrete was used as RLA by crushing it into fine particles, and used to replace fine limestone aggregate of up to 45% by weight.
