Download or read book Effects of Ground Granulated Blast Furnace Slags on Some Properties of Pastes Mortars and Concretes written by VS. Dubovoy and published by . This book was released on 1986 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were performed under separate contracts at different times for three manufacturers of ground granulated blast-furnace slag to determine the performance of their products with portland cement. Physical tests were performed on pastes, mortars, and concretes to determine both freshly mixed and hardened properties. The effects of gypsum addition, fineness of slag, and levels of replacement in cement-slag combinations were evaluated. Physical tests performed on pastes and mortars included time of setting, compressive strength, and volume stability. In the mortar compressive strength series, various curing regimens were evaluated with respect to strength development. Included were normal moist curing at 23°C (73°F) and 4.4°C (40°F) and 100% relative humidity, and accelerated atmospheric curing [71°C(160°F)] and 100% relative humidity. Tests conducted on concretes containing slag included compressive strength, freeze-thaw durability, and resistance to deicer chemicals (scaling). Measurements of air-void systems of hardened concretes were made. Results generally show that use of slag can be beneficial without resulting in significant technical problems or adverse construction problems.

This book was released on 2014-11-20 with total page 855 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet’s total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders Considers performance in adverse environmental conditions. Offers equal emphasis on the science behind the technology and its use in civil engineering.
