Product Information

FR230 Intucompound is a gypsum based mortar used to reinstate the fire resistance performance of floor & wall constructions where they have been breached with apertures for the penetration of single or multiple services. FR230 provides a safe working platform for loads up to 2.5 kN/m² when installed in full accordance to our The first use in siege warfare was at the 1453 siege of Constantinople by Mehmed the Conqueror. An Italian account of the 1456 siege of Belgrade by Giovanni da Tagliacozzo states that the Ottoman Turks used seven mortars that fired "stone shots one Italian mile high". [6] The time of flight of these was apparently long enough that casualties could be avoided by posting observers to give warning of their trajectories.

From the 17th to the mid 20th century, very heavy, relatively immobile siege mortars were used, of up to one metre calibre, often made of cast iron and with an outside barrel diameter many times that of the bore diameter. An early example was Roaring Meg, with a 15.5-inch (390mm) barrel diameter and firing a 220lb (100kg) hollow ball filled with gunpowder and used during the English Civil War in 1646. Each Platoon is commanded by at least one WO2 and manned by Sgts and CSgts selected as SMEs from the Field Army.

Light and medium mortars are easy to move around. They are usually used by infantry units. Mortars can fire from a trench or defilade. weber fire mortar on kemiallisesti ja keraamisesti sitoutuva kuivalaasti puulämmitteisten tulipesien muuraukseen.

Heavier mortars are fired by three to five men. [1] Lighter mortars can be fired from anywhere that gives a good firing position. However, medium mortars are usually fired from prepared, well fortified positions. [1] Design [ change | change source ] LLR 81mm mortar of the 2e REI.

Mortars are usually smaller and lighter than howitzers and field guns. When the mortar bomb is launched, it descends at a very steep angle (almost straight down). [1] All surfaces to which Vitcas Heatproof Mortar is to be applied should be clean and free from grease, dust and dirt. Ammunition for mortars generally comes in two main varieties: fin-stabilised and spin-stabilised. Examples of the former have short fins on their posterior portion, which control the path of the bomb in flight. Spin-stabilised mortar bombs rotate as they travel along and leave the mortar tube, which stabilises them in much the same way as a rifle bullet. Both types of rounds can be either illumination ( infrared or visible illumination), smoke, high explosive, and training rounds. Mortar bombs are often referred to, incorrectly, as "mortars". [25]

Mortars were very useful in the muddy trenches of the Western Front. A mortar round could be aimed to fall straight into a trench because of the deep angle that the bombs fell at.FR230 is suitable for the following service penetrations: single and bunched cables, cable trays/ladders/baskets, non-combustible pipes. Also suitable for cable trunking, combustible pipes, insulated non-combustible pipes, in conjunction with a suitable Nullifire closer device (for example FP302 Intustrap or FS709 HP). 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. A 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. It’s widely accepted that, without communications, even the most organised and well-disciplined force will grind to a halt. Without communications we are unable to direct resources, including manpower, to where they are required.
