BlackArch 2016.12.20 comes with 100+ new tools. The updated ISOs, which are available for both 64-bit and 32-bit deployments, take about 6.2GB space. This release also ships with the new Linux 4.8 kernel. The complete changelog is:
dry concrete. Definition. Concrete that has a low water content, making it relatively stiff. The effects are a lower water-cement ratio, less pressure on forms, lower heat of hydration, and a consistency that allows for placement on a sloping surface.
Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardening process continues for years meaning that concrete gets stronger as it gets older.
