Resorcinol (or resorcin) is a phenolic compound. It is an organic compound with the formula C 6 H 4 (OH) 2. It is one of three isomeric benzenediols, the 1,3-isomer (or meta-isomer). Resorcinol crystallizes from benzene as colorless needles that are readily soluble in water, alcohol, and ether, but insoluble in chloroform and carbon disulfide. [6]
Diglycidyl resorcinol ether, also called Resorcinol diglycidyl ether (RDGE) is a liquid aromatic organic chemical compound and chemically a glycidyl ether. [2] [3] The formula is C 12 H 14 O 4 [4] and the CAS Registry Number 101-90-6. [5] It is one of a number of glycidyl ethers available commercially that are used to reduce the viscosity of ...
Resorcinol glue, also known as resorcinol-formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light. [ 1 ] [ 2 ] The adhesive, introduced in 1943, has been popular in aircraft and boat construction.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]

The C 4-benzenes are a class of organic aromatic compounds which contain a benzene ring and four other carbon atoms. There are three tetramethylbenzenes, six dimethylethylbenzenes, three diethylbenzenes, three isopropylmethylbenzenes, three n-propylmethylbenzenes and four butylbenzenes.
K D = around 10 for artificial interlocking concrete blocks; S r = (ρ r / ρ w is the relative density of rock, i.e. (ρ r / ρ w - 1) = around 1.58 for granite in sea water; ρ r and ρ w are the densities of rock and (sea)water (-) θ is the angle of revetment with the horizontal
Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.
