From Pores to Pavement: Advanced Modeling of Aluminosilicates for Scalable Carbon Capture in Concrete

Advanced Science, EarlyView.
This study presents a transferable modeling framework for carbon capture using aluminosilicates, integrating Universal Isotherm Modeling with experimental data. It reveals how ultramicropores, alumina content, and amine functionalization influence CO2 adsorption energetics.

Asphalt Cement Containing AC-13, HR-522, Final Report, 1988 [PDF]

, 1988
Stopping and turning maneuvers on high traffic volume asphalt cement concrete surfaced roads and streets often cause distortion of the pavement. Distortion may show up as excessive rutting in the wheel path, shoving of the pavement and/or rippling of

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Porous Concrete Design [PDF]

, 2017
Porous concrete is a special kind of concrete that has high porosity. The only difference between porous concrete and normal concrete is that a porous concrete mix does not consist of sand or other small particles.

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

MANAGEMENT OF CEMENT-CONCRETE ROAD PAVEMENT STRUCTURE

Journal of Engineering Science (Chişinău), 2019
The aim of the research is to study the effect of operating factors on the pavement and optimize the composition of the modified additive for controlling the structure of concrete. The choice of modifiers for concrete mixtures is mainly made empirically and specifically tied to specific engineering tasks.
