Enhancing Concrete Compression Strength with Potassium Polyacrylate as an Internal Curing Agent

Riva, Max; Jayo, Jhon F.; Cerna, Nhell; Diaz, Felix; Liza, Rafael (IEEE, 2024)
Acceso restringido

In this paper, the effectiveness of potassium poly-acrylate as an internal curing agent for improving the compressive strength of concrete is investigated. Concrete specimens designed to achieve a strength of 210 kg/cm ...
Quantum Effects without Quantum Fields: Feynman's Amplitudes in Classical Electrodynamics

Nieto-Chaupis, Huber (Institute of Electrical and Electronics Engineers, 2019-12)
Acceso restringido

We derived their classical counterpart of Feynman's amplitudes for electron and photons interaction in the super-intense regime through the Hartemann-Kerman theory in conjunction to the Reiss-Eberly criterion of quantization. ...
