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.
Considered by some to be a suitable alternative to wet grouting, dry brush-in relies on the complete and total absence of water from the mortar mix and pavement surface during the placement phase to allow the water-free, bone-dry sand/cement mix to flow into the empty joints. The surface of the paving must be completely dry. Any residual dampness will cause the sand/cement mix to stick and will probably result in a stain. Consequently, this is a technique that is only really practical during the summer months. A 3:1 ratio of sand and cement are mixed without the addition of ANY water.
