With the widespread use of high-strength concrete structures (HC), the impact of pore structure on their performance has become a current research focus. The mechanism by which different curing conditions and freeze-thaw cycles influence the evolution of
If steels 3 and 4 now are withdrawn from a rather outer part of the coil, the straightening is reduced due to the bigger coil radius, which subsequently leads to smaller residual stresses. This could explain the different behavior of steels 1 and 2 compared to steels 3 and 4. Nevertheless...
To improve the bonding strength of soy protein adhesives on the one hand and to study the feasibility of decreasing the use of synthetic resins and partially replacing them with bio-based adhesives on the other hand, different formaldehyde-to-urea molar ratios were used in combination with a ...
Based on the addition of rare earth in steel, the combination of Ce with activity O and S in the steel had lower Gibbs free energy, and it was easy to generate CeAlO3, Ce2O2S, and Ce2O3. Meanwhile, the inclusion size decreased obviously, but the amount of inclusions increased. The ...
Average compressive strength values were determined from 3 measurements on cube samples. 3. Results 3.1. Phase Analysis of Un-Treated and Calcined Kaolinite Samples with and without Limestone Additions K and KL samples were analyzed by XRD before and after calcination to determine the phase ...
