Citric‐Acid Polyester‐Modified Melamine–Formaldehyde Resins: Mechanistic Insights and Implications for Greener Decorative Laminates

Journal of Applied Polymer Science, EarlyView.
Driven by the need for more sustainable materials in the laminate industry, poly(glycerol citrate) was introduced as a bio‐based modifier that significantly altered the cure kinetics and structural evolution of melamine–formaldehyde resins. Correlated FTIR, DSC, TGA, and rheological analyses revealed accelerated network formation, enabling lower ...

Analysis of the punching behavior of RC flat slabs with horizontal and vertical shear reinforcement

MATEC Web of Conferences, 2017
Punching failure is one of the major drawbacks of using flat slabs in the design of reinforced concrete structures. Punching shear analysis is very complicated which appears clearly in the large variation of the equations used by the different codes in ...

Impact of A‐/B‐Type Starch Granule Ratios in Reconstituted Wheat Flour on Dough and Bread Properties

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Wheat starch comprises two granule populations, A‐ and B‐type, whose relative proportions influence the quality of wheat‐based products. In this study, 20% of wheat flour was replaced with blends of starch mixtures (A‐/B‐type ratios 100:0–0:100) and vital wheat gluten to investigate their effects on dough and bread ...

Punching shear of RC slabs exposed to fire: assessment of load-bearing capacity based on European and American provisions. Part 1 – General code requirements [PDF]

Archives of Civil Engineering
Slab-column connection is one of the most critical points in reinforced concrete structures. Punching shear capacity of this connection must be properly determined in both the persistent design situation and the accidental design situation of fire ...

Effect of reinforcement corrosion on punching shear of RC flat slabs incorporating steel and synthetic fibers

Case Studies in Construction Materials
Reinforcement corrosion weakens the punching shear capacity of RC flat slabs. This study tested twelve large-scale slabs (1500 × 1500 × 100 mm) with hooked-end steel or macro-synthetic fibers (0.5–1.0 % by volume) and control samples.

Usage of prestressed vertical bolts for retrofitting flat slabs damaged due to punching shear

Alexandria Engineering Journal, 2015
Sometimes, due to design mistakes or a change in the construction function results in heavier or additional loads, a flat slab may be failed by punching shear which is considered as a brittle failure.
