Low carbon steel weld structures generally exhibit a very linear stress-strain relationship. In the study of strength of materials, the compressive strength is the capacity of a material or structure to withstand loads tending to reduce size of structure. It is mainly measured by plotting applied ...

The strength at 28 days of 20% fly ash cement mortars however, was found to be highest with 1% carbon nanotubes addition where the compressive strength at 28 days was 51.8 MPa. This was higher than the reference mix of FA mortar without CNTs where the strength was at 47.2 MPa. It was ...
(2022) added 0–4% nano-SiO2 to the LCFA-based AAC containing 0.5% micro-carbon fiber which was activated with 12 mol NaOH and Na2SiO3 solution. It has been observed that the inclusion of nano-SiO2 results in an increase in the compressive strength up to 3% whereas the inclusion of a ...
There is a complex high-dimensional nonlinear mapping relationship between the compressive strength of High-Performance Concrete (HPC) and its components, which has great influence on the accurate prediction of compressive strength. In this paper, an efficient robust software calculation strategy combining...
The longitudinal thin-strip glubam retains decent compressive properties, while the transverse specimens stay a stable compressive strength along all fungal tests. The paper reports the experimental values of mass loss, color changes, compressive strengths, modulus of elasticity in compression, and ...
Compressive strength prediction and low-carbon optimization of fly ash geopolymer concrete based on big data and ensemble learning Portland cement concrete (PCC) is a major contributor to human-made CO2 emissions. To address this environmental impact, fly ash geopolymer concrete (FAGC)... P Jiang...
Although high carbon martensitic steels are well known for their industrial utility in high abrasion and extreme operating environments, due to their hardness and strength, the compressive stability of their retained austenite, and the implications for the steels' performance and potential uses, is not...
We experimentally determined the decrease of residual compressive strength of the pultruded glass-fiber laminate after tension-compression cyclic loading. The adapted Arcan rig was used for tension-compression fatigue tests. The cyclic load was applied with the critical stress ratio R=−0.87. The res...
In this study, four Artificial intelligence (AI) - based machine learning models were developed to estimate the Residual compressive strength (RCS) value of concrete supported with nano additives of Nanocarbon tubes (NCTs) and Nano alumina (NAl), after exposure to elevated temperatures ranging from...
