There are two application methods for shotcrete. dry-mix – the dry mixture of cement and aggregates is filled into the machine and conveyed with compressed air through the hoses. The water needed for the hydration is added at the nozzle. wet-mix – the mixes are prepared with all necessary water for hydration.
Foam concrete is a versatile building material with a simple production method that is relatively inexpensive compared to autoclave aerated concrete. [1] Foam concrete compounds utilising fly ash in the slurry mix is cheaper still, and has less environmental impact. Foam concrete is produced in a variety of densities from 200 kg/m 3 to 1,600 kg ...
Self-consolidating concrete or self-compacting concrete ( SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external ...
The SAFER barrier at the Milwaukee Mile The SAFER barrier (teal) at Homestead-Miami Speedway after an impact from Kurt Busch's racecar Cutaway of a SAFER barrier. The Steel And Foam Energy Reduction Barrier (SAFER Barrier), sometimes generically referred to as a soft wall, is a technology found on oval automobile race tracks and high speed sections of road and street tracks, intended to absorb ...
Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with ...
A layer of polyurethane foam is sprayed on the interior of the form. (Its purposes are to give rigidity to the air form, secure the re-bar in place, provide support for spraying in the concrete mixture, and insulate the final structure.) Rebar is attached to the outside layer of foam, using clips that are attached to the foam.
