This study presents the compressive strength characteristics of carbon, palm kernel and steel fibrereinforced polymer concrete. The binder was locally produced by dissolving 600g of styrofoam in a litre of gasoline ,it was then mixed with river sand at a binder aggregate ratio of 18% binder to ...
(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 ...
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 ...
selling point is that the mineral itself improves the compressive(压缩的)strength for the concrete, which means producers like Thomas Concrete can use less cement in their mixtures and still achieve the same strength with fewer emissions.Compression tests prove that the concrete made with Carbon Cure...
The compressive strength of circular concrete filled steel tubular (C-CFST) stubs strengthened with carbon fiber reinforced polymer (CFRP) is studied theoretically. According to previous experimental results, the failure process and mechanism of circular CFRP-concrete filled steel tubular (C-CFRP-CFST...
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...
5.Influential factors of compressive strength for steel fiber reinforced high-strength concrete钢纤维高强混凝土抗压强度影响因素 6."Carbon steel has high and low temperature strength, is very tough and has excellent fatigue strength."碳钢具有高温和低温强度,具有很高的韧度和优异的抗疲劳强度。
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...
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...
