Cement is a binder, a substance used in construction that sets, hardens and adheres to other materials, binding them together. Cement is seldom used solely, but is used to bind sand and gravel (aggregate) together. Cement is used with fine aggregate to produce mortar for masonry, or with sand and gravel aggregates to produce concrete.

Cements used in construction are usually inorganic, often lime or calcium silicate based, and can be characterized as being either hydraulic or non-hydraulic, depending upon the ability of the cement to set in the presence of water

Hydrogen, is the chemical element of atomic number 1, represented by the symbol H, is the lightest in the table of elements, this gas is flammable, colorless, odorless, non-metallic and insoluble in water.

Hydrogen constitutes about 75% of the visible matter of the universe.

It is found mainly in the form of hydrogen gas (H2) in the stars and in the gaseous planets, and also appears attached to other elements forming a great variety of chemical compounds, such as water (H2O) and most organic compounds.

Water is a transparent and nearly colorless che,o la substance that is the main constituent of Earth's streams , lakes, and oceans , and the fluids of most living organism . Its chemical fórmula  is H ₂ O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity.

Diamond is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face centered cubic crystal structure called a diamond lattice. Diamond is lesstable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material.

Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth's surface through deep volcanics eruptions by magma, which cools into igneous rocks known as kimbertiles and lamproites. Diamonds can also be produced synthetically in a HPHT method which approximately simulates the conditions in the Earth's mantle.
