| 1 | Self-Healing Concrete with Crystalline Admixture——A Review显示文摘The scope of the present paper is to understand the effects of crystalline admixture on the selfhealing capacity of the cementitious composites. Previous studies were examined and a conclusion was drawn to the effect that different additives to crystalline admixture tend to improve self-healing of concrete for larger cracks. It is recommended that initial treatment with chemical admixture can stimulate and heal further cracks and it has the better repeatability trend in mixing with the concretes and mechanical recovery is possible even under repetitive preloading. Effective self-healing with chemical admixtures even under open-air exposure, leads to study the importance of a service ability design parameter including the maximum allowable crack width by repeatability analysis as a function of the exposure with the concept of sealable crack width. | A Ravitheja Dr T Chandra Sekhara Reddy Dr C Sashidhar | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，5： | 6 |
| 2 | Improvising the Self-Healing Capabilities of Concrete Using Different Pozzolanic Materials and Crystalline Admixtures显示文摘To analyse the self-healing capacities in terms of mechanical performance of the pozzolanic materials,such as,fly ash,metakaolin and silica fume and crystalline admixtures.Pre-cracked concrete cubes with about 0.05 mm width were exposed to four different environmental conditions at different exposure times in order to determine the effect of temperature and water availability on the self-healing potential.After the exposure,the control and tested concrete cubes were evaluated for regained strength,void reduction,corrosion inhibition,damp proofing,relative impermeability and durability.The samples with SF10CA have better cementitious filling and low percentage of voids and water absorption. | A Ravitheja T Chandra Sekhara Reddy C Sashidhar | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，3： | 1 |
| 3 | Influence of Nano-Materials on Mechanical and Permeation Characteristics of High Strength Concrete显示文摘Efforts have been made to evaluate the influences of the addition of nanoparticles on the strength,durability and mineralogical changes of high strength concrete(HSC).Therefore,mixes were prepared for conventional concrete mix(CCM)of M80 grade.Further,various mixes were prepared by replacing cementitious materials initially with 1%Nano-CaCO_(3)(NC),2%NC,3%NC in the CCM,and then 1%NC and Nano-SiO_(2)(NS)NS,2%NC and NS,3%NC and NS(NC and NS were in equal proportion)in the CCM.The developed concretes were then evaluated for mechanical properties,permeation characteristics,and mineralogical studies.From the studies,it is found that the concrete at 2%NCS possesses superior mechanical and superior permeation characteristics of all the mixes.A clear variation in the mineralogical structure with the addition of nanoparticles has been observed. | K V S Gopala Krishna Sastry M Srinivasula Reddy A Ravitheja | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，3： | 0 |
