Custom element japanese name: Semento
Custom element english name: Cement Release
The element is based on: Fire + Earth + Water + Chakra
Facts that prove the element to be possible (in the manga context): We have seen in manga that a lava user name, Kurotsuchi have used a technique called ''
Lava Release: Quicklime Congealing Technique
'' and the substance can act in a similar manner to quick-drying cement afterward she used
(Suiton: Mizurappa) - Water Release: Water Horn
to harden the cement and trap Kabuto. So i thought of expanding this idea of using earth release(to create its base mineral like limestone/clay) and using fire release(to heat them up) and lastly to use water release to (make the substance harden) and not forgetting to mix them with normal chakra too.
Idea behind its creation: Cement is made by heating limestone (calcium carbonate) with small quantities of other materials (such as clay) to 1450 °C in a kiln, in a process known as calcination, whereby a molecule of carbon dioxide is liberated from the calcium carbonate to form calcium oxide, or quicklime, which is then blended with the other materials that have been included in the mix. The resulting hard substance, called 'clinker', is then ground with a small amount of gypsum into a powder to make 'Ordinary Portland Cement', the most commonly used type of cement (often referred to as OPC). Portland cement is a basic ingredient of concrete, mortar and most non-speciality grout. The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element. Portland cement may be grey or white. A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln, replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications. Selected waste and by-products containing useful minerals such as calcium, silica, alumina, and iron can be used as raw materials in the kiln, replacing raw materials such as clay, shale, and limestone. Because some materials have both useful mineral content and recoverable calorific value, the distinction between alternative fuels and raw materials is not always clear. For example, sewage sludge has a low but significant calorific value, and burns to give ash containing minerals useful in the clinker matrix, Cement manufacturing releases CO2 in the atmosphere both directly when calcium carbonate is heated, producing lime and carbon dioxide, and also indirectly through the use of energy if its production involves the emission of CO2. The cement industry is the second largest CO2 emitting industry behind power generation. The cement industry produces about 5% of global man-made CO2 emissions, of which 50% is from the chemical process, and 40% from burning fuel. The amount of CO2 emitted by the cement industry is nearly 900 kg of CO2 for every 1000 kg of cement produced. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions that occur independently of the mixture's water content; they can harden even underwater or when constantly exposed to wet weather. The chemical reaction that results when the anhydrous cement powder is mixed with water produces hydrates that are not water-soluble. Non-hydraulic cements (e.g., lime and gypsum plaster) must be kept dry in order to retain their strength. The most important use of cement is the production of mortar and concrete—the bonding of natural or artificial aggregates to form a strong building material that is durable in the face of normal environmental effects. Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures. Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration. The water reacts with the cement, which bonds the other components together, eventually creating a robust stone-like material. Concrete is used to make pavements, pipe, architectural structures, foundations, motorways/roads, bridges/overpasses, parking structures, brick/block walls and footings for gates, fences and poles. Concrete is used more than any other man-made material in the world.
Different type of cement in all around the world:
Portland blastf.urnace cement
All compositions produce high ultimate strength, but as slag content is increased, early strength is reduced, while sulfate resistance increases and heat evolution diminishes.
Portland flyash cement
contains up to 30 % fly ash. The fly ash is pozzolanic, so that ultimate strength is maintained. Because fly ash addition allows a lower concrete water content
Portland pozzolan cement
includes fly ash cement, since fly ash is a pozzolan, but also includes cements made from other natural or artificial pozzolans
Portland silica fume cement
Addition of silica fume can yield exceptionally high strengths, and cements containing 5–20 % silica fume are occasionally produced.
(cement that not only hardens by reacting with water but also forms a water-resistant product)
Is made by heating, in a kiln, a homogeneous mixture of raw materials to a sintering temperature, which is about 1450 °C for modern cements. The aluminium oxide and iron oxide are present as a flux and contribute little to the strength.
Are used for preparing bricklaying mortars and stuccos, and must not be used in concrete
effects of drying shrinkage that is normally encountered with hydraulic cements. This allows large floor slabs (up to 60 m square) to be prepared without contraction joints.

Conditions to be able to use it: Complete mastery of the Earth & Fire & Water elements and must have large masses amount of chakra
Is weak to:
Lighting: Due to the destruction power, it can easily blast through it
Strong Fire: As cement are used to make building/roof, so an strong fire jutsu is enough to punch through it.
Earth: Since it is liquid, it would be weak against earth for the same reasons as water.
Strong Wind: Wind can't cut through it but it is able to slightly push it back
Ice: Able to freeze it therefore stopping it from moving.
Is strong against:
Water: It can stop the flow of the water, Similar to earth
Fire: Heat will only cause the it to become hotter since cement was heated up to 1450 °C and because of its properties it can't be vaporized.
Lighting: Cement is conductive to lightning
Water: denser than water so it overpower it in a clash.
Co-creators (if any): None
