A cement accelerator is an admixture for the use in concrete, mortar, rendering or screeds. The addition of an accelerator speeds the setting time and thus cure time starts earlier. [ 1 ] This allows concrete to be placed in winter with reduced risk of frost damage. [ 2 ]
When paired with the M1129 Stryker double-V-hull mortar carrier vehicle (MCVV) mobile platform, it increases the battlespace where the guided rounds can be used. [13] The Army bought 5,480 mortar guidance kits in response to an operational needs statement in Afghanistan, sometimes hitting as close as 2.2 meters from the target.

Mortar holding weathered bricks. Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colours or patterns to masonry walls.
The concrete or mortar is formulated to be sticky and resist flowing when at rest to allow use on walls and ceilings, but exhibit sufficient shear thinning to be easily plumbable through hoses. Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions invented by Akeley.
But, GABA breaks down about twice as fast as glutamate so the relaxing effects wear off faster than the excitatory effects. After three or four drinks, the brain can end up overstimulated and this ...
Simplified diagram of a multistage coilgun with three coils, a barrel, and a ferromagnetic projectile. A coilgun is a type of mass driver consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity.

Most modern mortar systems consist of four main components: a barrel, a base plate, a bipod and a sight. Modern mortars normally range in calibre from 60 mm (2.36 in) to 120 mm (4.72 in). However, both larger and smaller mortars have been produced. The modern mortar is a muzzle-loaded weapon and relatively simple to operate.
