Effects Of Organic Corrosion Inhibitors On The Performance Of Repair Mortars, Ominda Nanayakkara Dr.

International Conference on Durability of Concrete Structures

Reinforced concrete (RC) structures are severely degraded due to the corrosion of the embedded reinforcing steel, and hence, the upgrading of RC structures is essential. Repairing mortar is widely used to improve durability and strengthen structures; however, further repairing might be required considering the extended life of the structure. The use of inhibitors to protect the reinforcement from corrosion has become of great interest. Therefore, it is vital to study the potential of using corrosion inhibitors in a newly repaired system.

This study investigated the performance of a commercially available polymer-modified mortar with migrating and admixed corrosion inhibitors. The study …

Investigation On Structural Heritability And Durability Of High Sulfate Resistance Portland Cement Mortar Modified By Aluminum Salt, Jun Xu

International Conference on Durability of Concrete Structures

The essential hydration and hardened properties of high sulfate resistance Portland cement paste/mortar were investigated with Al₂(SO₄)₃ as admixture. Experiment results showed that that the addition of Al₂(SO₄)₃ promoted the hydration of HSRP cement pastes, and the hydration rate accelerated with the increase of the addition amount. The mechanical properties and chloride diffusion coefficient of cement mortar were obviously improved with 0.25% Al₂(SO₄)₃ addition . For instance, the compressive strength of AS0.25 cement mortars was 24.8% higher than AS0 samples and the chloride ion migration …

Characterization And Quantification Of Fibrin Gel Mechanics With Fibroblast Invasion, Nicklaus Iavagnilio, Sarah Calve, Adrian Buganza-Tepole

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cutaneous wounds undergo an intricate healing process stimulated by a variety of local mechanical and biological stimuli that lead to patterns of growth and remodeling. Despite significant research in dermal wound healing, pathological scarring is still common particularly in wounds closed under mechanical stress, or large wounds left to heal by secondary intention. The purpose of this study is to utilize previously established wound healing models using fibrin gels and fibroblasts to better understand the functional relationships of the biological processes of normal compared to abnormal wound healing. Increases in uni-axial strain and transforming growth factor beta-1 concentration have been …

Effect Of Nano-Sio2 Content On The Setting Time And Mechanical Properties Of Tricalcium Silicate, Zhenhai Xu, Zonghui Zhou, Xin Cheng

International Conference on Durability of Concrete Structures

Using analytically pure calcium carbonate and silica as raw materials, high purity tricalcium silicate (C₃S) is prepared by solid-state reaction. The tricalcium silicate was sintered at a temperature of 1550°C with the heat preservation time of 6 h. The final sample needs three times of calcination circles. Ultrasonic cleaning machine was used to disperse the water and different amount of nano-SiO₂ (0, 1, 2, and 3 wt%) for 5 min, then mixed with C₃S, and formed into standard blocks. The setting time and compressive strength of each age (1, 3, 7, and 28 days) was …
