2. Effects of Crack Width on Carbonation Penetration: Implications for Crack-Dating

Description:: Carbonation, a neutralizing reaction in cement paste, can be used to date cracks in cementitious materials. Currently, comparison between two cracks is the only method available to predict a relative age with carbonation. These two crack studies require a crack of known age in a similar material with similar exposure...

3. Blast Induced Micrometer Response of Cracks in Concrete Block Structures

Description:: Blasting and climatological response of cracks are compared for structures constructed of concrete block typical of home construction in Europe. While much has been written comparing micrometer crack response of wood frame structures typical of residential construction in North America, little has been written concerning response of structures more typical...

4. Response of Uncracked Drywall Joints and Panels to Blast Vibration and Weather

Description:: Cracking is one of the most common concerns cited by owners of structures adjacent to construction or mining blasting. While a large database of case studies documenting the relative insignificance of ground motion induced by responsible blasting compared to weather effects on cracks in nearby structures has been established, the...

5. Influence of Nucleation Seeding on the Compressive Strength of Ordinary Portland Cement and Alkali Activated Blast-Furnace Slag (Infrastructure Technology Institute Year 2 Final Report)

Description:: A study is conducted to determine the effects on the early hydration kinetics and compressive strength by seeding of Portland cement and alkali-activated blast furnace slag with a pure form of calcium silicate hydrate (C-S-H). The effects of C-S-H seeding during the early nucleation and growth period of each type...

6. Early Age Properties of Portland Cement Pastes Investigated with Ultrasonic Shear Waves and Numerical Simulation (preprint)

Description:: In this paper, the correlation of reflection loss measured by an ultrasonic shear wave reflection method and the microstructure in cement-based material is investigated. Three cement pastes (Portland cement type I) with different water-cement ratios (0.35, 0.50 and 0.60) cured at 25 °C were examined. The ultrasonic shear wave reflection...

8. Health monitoring of early age concrete

Description:: The setting and hardening process of concrete can be considered as the most critical time period during the life of a concrete structure. To assure high quality and avoid problems in performance throughout the life of the material, it is essential to have reliable information about the early age properties...

9. Optimization of Self Consolidating Concrete for Slip-form pavement

Description:: The concrete currently used in the slip-form paving process is a low slump concrete that requires both internal and external vibration in order to achieve satisfactory compaction. The use of vibrator fingers for the internal vibration often leads to trails on the surface of the pavement and to segregation around...
