SYSTEMATIC FORMULATION OF HIGH PERFORMANCE CONCRETE PAVEMENT

Civil Engineering Dimension, 2005
Following a 25-1 fractional factorial design concept, an experiment was planned ; sixteen experimental mixes were calculated from a basic mix (cement : sand : aggregates : fly ash = 1 : 1.3 : 2.6 : 0.8 and W/C ratio of 0.37) and determined changes ...

Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects

Advanced Science, EarlyView.
A cascaded third‐order nonlinear system generates an itinerant frequency comb with the comb center frequency decoupled from the cavity resonance. This enables arbitrary spectral scaling, flexible spacing adjustments, and real‐time central‐frequency engineering, allowing comb splicing and subdivision. The resulting versatility and reconfigurability open

Influence of the Dosage of Super Plasticizer on Properties of High Performance Concrete

High-performance concrete (HPC) is defined as concrete that meets special combinations of performance and uniformity requirements. That cannot always be achieved routinely using conventional constituents and ordinary mixing, placing, and curing practices.

Machine Learning Potential for Calcium Silicate Hydrates With Broad Compositional and Structural Diversity

Advanced Science, EarlyView.
Existing machine learning potentials remain limited in their ability to generalize across the broad chemical and structural variability of C–S–H. Here, a representative DFT‐labeled dataset is constructed through large‐scale model generation, redundancy‐controlled screening, first‐principles optimization, and targeted sampling of non‐equilibrium ...

Structural performance of precast/prestressed bridge girders built with ultra high performance concrete

, 2008
With its very high strength, high modulus and very low permeability, ultra high performance concrete (UHPC) can provide major improvements over conventional high performance concrete (HPC) in terms of structural efficiency, durability and cost ...

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

Advanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Measures to improve the Strength Development of Low Carbon Sprayed Concrete

A characteristic feature of sprayed concrete is the fast setting and hardening. This is typically achieved through a high content of Portland Cement clinker in the concrete in combination with a liquid alkali-free accelerator, which is added at the ...

Scalable Fabrication of MOF Glass Membranes for Gas Separation via Stepwise Phase Transition

Advanced Science, EarlyView.
Metal‐organic framework (MOF) glass membranes, with their excellent processability and permanent pore structure, have great potential for gas separation applications. However, during large‐scale fabrication, defects and obvious cracks are prone to occur due to the limitations of powder processing.
