Alkali-aggregate reaction — the reaction that occurs over time between highly alkaline cement paste and noncrystalline silicon dioxide — can lead to a loss of concrete strength. A new ASTM International standard provides guidance on how to address the potential for such deleterious reactions in concrete construction. The new standard is ASTM C1778 , Guide for Reducing the Risk of Deleterious…, ASTM Committee C09 Next Meeting:, June 14-17, 2015, June committee week, Anaheim, Calif., Technical Contact:, Thano Drimalas, University of Texas at Austin, Manor, Texas, tel +1.512.471.1630; thano.drimalas@mail.utexas.edu ; Jason H.

Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM International Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 subcommittee, D28.02 on Liquid Phase…, WK47401, Xylenol Orange Dye, The xylenol orange dye test is a way to determine the relative adsorption rate of unused or reactivated carbons by adsorption of xylenol orange from aqueous solution. This is an important means for deciding which type of activated carbon to use to a specific water treatment application. “Activated carbon performance can roughly be defined as a combination of the ability to adsorb a particular…, WK47421, Particle Size Distribution, Mercury flue gas, home water filters and potable water treatment are the main applications in which powdered and fine mesh carbons are used. A proposed new test method will describe how a laser light scattering technique can determine the particle size distribution of fine mesh activated carbon.
