Perbandingan Kuat Tekan Beton Ringan Dengan Metoda Rancang-campur Aci Dan Dreux-corrise [PDF]

, 2011
Lightweight concrete is one of solving problems to deficiency or loss that is about the size of the dead load weight of the concrete itself. Generally, lightweight concrete has the same mix-design with normal concrete, except that coarse aggregate in ...

Enhancing Concrete Strength: The Impact of Silica Admixture [PDF]

E3S Web of Conferences
Researchers set out to determine if and by what margins Nano silica reduces the compressive strength of concrete. From seven percent to seventeen percent, silica was an ingredient in the concrete mixture. The mix design for M20 grade concrete was cast in

Recycled Piezoelectric Materials with Competitive Second‐Life Functional Properties

Advanced Electronic Materials, EarlyView.
The essential piezoelectric ceramics with heavy ecological footprints are not sufficiently recycled. This work demonstrates the feasibility of recycling different types of piezoelectric ceramics using different binders, where the terpolymer binder with relatively large permittivity facilitated superior retention of properties after recycling, promoting

Pengaruh Sulfat terhadap Kuat Tekan Beton dengan Variasi Bubuk Kaca Substitusi Semen dengan W/C 0,4 dan 0,5 [PDF]

, 2013
The aggressive environment can damage concrete especially sulfate attack which would decrease compressive strength of concrete and also cause corrosion. Therefore, the additive was added into concrete mixture.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

Advanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Spatial description of concrete characteristics [PDF]

, 2016
This work has the objective to simulate the variation of the compressive resistance strength of concrete along the height of a structural member. The concrete compressive strength is calculated with a formula, which has been previously analysed.

Strength Prediction Model for Accelerated Cured Fly-Ash Based Concrete

Mehran University Research Journal of Engineering and Technology, 2019
The most important property of concrete is its compressive strength, which is carried out after 28-days proper curing of concrete. This test is affected by other factors like the condition of curing, water to cement ratio, method of transportation ...

Machine Learning‐Assisted Second‐Order Perturbation Theory for Chemical Potential Correction Toward Hubbard U Determination

Advanced Intelligent Discovery, EarlyView.
In this work, the Doubao large language model (LLM) is involved in the formula derivation processes for Hubbard U determination regarding the second‐order perturbations of the chemical potential. The core ML tool is optimized for physical domain knowledge, which is not limited to parameter prediction but rather serves as an interactive physical theory ...
