FR230 is used to stop the spread of fire and smoke around services that pass through compartment walls and floors, whilst providing a load bearing capability (refer to application instructions). The system also provides thermal, acoustic and air sealing performance. Most mortars used today are made up of a barrel, a plate for the barrel to stand on, and a bipod. [1] 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 60mm (2.36in) to 120mm (4.72in). However, both larger and smaller mortars have been produced. The modern mortar is a muzzle-loaded weapon and relatively simple to operate. It consists of a barrel into which the gunners drop a mortar round. When the round reaches the base of the barrel it hits a fixed firing pin that fires the round. The barrel is generally set at an angle of between 45 and 85 degrees (800 to 1500 mils), with the higher angle producing a shorter horizontal trajectory. Some mortars have a moving firing pin, operated by a lanyard or trigger mechanism. Mortars are mainly medium calibre weapons. [1] However, mortars both bigger and smaller than this have been made. An example of a smaller mortar is the British 51 mm Light Mortar. The 51mm is carried by just one soldier. It is made up of only a tube and a base plate. A bigger example is the Soviet 2S4 M1975 Tyulpan ( tulip flower) 240mm self-propelled mortar. It also provides oversight to Communication Information Systems (CIS) and Assault Pioneer (AP) Training for Infantrymen at the Combat CIS School, Bovington and the Royal Engineer Warfare Wing delivered training for Assault Pioneers.

The Strix mortar round is a Swedish endphase-guided projectile fired from a 120mm mortar currently manufactured by Saab Bofors Dynamics. STRIX is fired like a conventional mortar round. The round contains an infrared imaging sensor that it uses to guide itself onto any tank or armoured fighting vehicle in the vicinity where it lands. The seeker is designed to ignore targets that are already burning. Launched from any 120mm mortar, STRIX has a normal range of up to 4.5km. The addition of a special sustainer motor increases the range to 7.5km. Permanent firestopping of cables, cable trays, and non-combustible pipes in medium to large wall and floor openingsA mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) [1] in high-arching ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Alliant Techsystems Takes Army Mortar Contract (Again)". defenseindustrydaily.com.

[1] Based at Waterloo Lines in Warminster, the SWS comprises two Training Divisions and Training Support Company.

The PFP FR EX fire resistant mortar will also maintain the acoustic design performance of surfaces. Where plastic pipes pass through the mortar, our pipe wraps should be used and can be easily added through the mortar and resealed with further mortar. Supplied in a 20kg bag, the mortar is easy to sand or drill, dries an off-white colour and is suitable for painting once cured. FR230 may be used to seal apertures in the separating element up to 1100 mm x 1100 mm in a floor or wall (without additionnal reinforcement requirements). The German Army studied the Siege of Port Arthur, where heavy artillery had been unable to destroy defensive structures like barbed wire and bunkers. As a result, they developed a short-barrelled rifled muzzle-loading mortar called the Minenwerfer. Heavily used during World War I, they were made in three sizes: 7.58cm (2.98in), 17cm (6.7in) and 25cm (9.8in). Modern mortars and their ammunition are generally much smaller and lighter than long range artillery such as guns and howitzers, which allows light and medium (typically, 60mm and 81mm/82mm) mortars to be considered light weapons; i.e. capable of transport by personnel without vehicle assistance.Direct Fire Support Division is a part of Specialist Weapons School. The Division comprises three wings that concentrate on running command courses in their different disciplines.

Easier to install – consistency can be varied for application with a trowel or commercially available pumps A mortar is quite simple and easy to use. Most are muzzleloaders made up of a tube that a gunner drops a bomb into. The tube is usually set at between 45 and 90 degrees angle to the ground. [1] The higher the angle, the shorter the range. When the bomb reaches the bottom of the tube it hits a firing pin. The mortar bomb's weight is enough to set off the firing pin which ignites the round and fires it. [1] Some larger mortars have a firing pin that is set off by using a string instead of automatically. The ammunition fired by mortars are properly called "bombs". One possible reason for this is that the fins that stabilise the round when it is flying, and the shape of the round makes it look like a bomb dropped from aircraft. [1] From the 18th to the early 20th century, very heavy siege mortars were used. These were very difficult to move around. These had up to one metre calibre. They were often made of cast iron. Smaller designs that were easier to move around were brought in during the First World War. Mortars are still used today.

It is suitable for all kinds of INTERIOR use, but must not to be used outdoors, unless it is protected from water by a roofed area or an additional render coat with a different material.
