Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume. Silica fume is a byproduct from the manufacture of silicon. It is an extremely fine powder (as fine as smoke) and ...
24/09/2020· However, in the long run, concrete can be the better economical choice. Concrete is more durable than asphalt and requires less maintenance. It can last for decades, while asphalt will generally only last 10 to 15 years before needing replacement. There are many repair options for concrete as well that can extend its life even further.
21/11/2017· When vehicles tires reach the end of their usable life, they can still find some use as a replacement for course aggregate in concrete mixes. Crumb rubber is car or truck tires that are ground up between the sizes of 3 10 mm. This mix has very poor compressive strength due to its high air content. It is believed that when this rubber is mixed in with the concrete air becomes trapped in with ...
Three ground granulated blastfurnace slag (GGBFS) concretes (30, 50 and 70% cement replacement) together with an OPC control, all designed for equal workability and 28day watercured strength, are compared when subjected to a variety of curing methods and exposure in both a temperate and a hot arid climate. The effect of replacement level on cube and core strengths, ultrasonic pulse velocity ...
The cost of concrete is less than conventional concrete. The concrete becomes environment friendly, due to use of waste industrial material. There is an increase of 17% compressive strength for 30% replacement of fine aggregate compare with normal concrete for 7 .
