Polymer concrete is a type of concrete that uses a polymer to replace lime-type cements as a binder. One specific type is epoxy granite , where the polymer used is exclusively epoxy . In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [ 1 ]
Polybutadiene forms by linking many 1,3-butadiene monomers to make a much longer polymer chain molecule. In terms of the connectivity of the polymer chain, butadiene can polymerize in three different ways, called cis, trans and vinyl. The cis and trans forms arise by connecting the butadiene molecules end-to-end, so-called 1,4-polymerisation.
Although butadiene breaks down quickly in the atmosphere, it is nevertheless found in ambient air in urban and suburban areas as a consequence of its constant emission from motor vehicles. [10] The name butadiene can also refer to the isomer, 1,2-butadiene, which is a cumulated diene with structure H 2 C=C=CH−CH 3.
Polymer concrete is concrete which uses polymers to bind the aggregate. Polymer concrete can gain a lot of strength in a short amount of time. For example, a polymer mix may reach 5000 psi in only four hours. Polymer concrete is generally more expensive than conventional concretes. [citation needed]
December 11th, 2019, aerial view of TPC plant and surrounding area. A processing unit at TPC's Port Neches butadiene manufacturing plant exploded in a series of explosions on Wednesday, November 27, 2019, the eve of Thanksgiving Day, and a fire raged at the facility. 60,000 residents were evacuated [18] [19] [5] within four miles of the facility, including parts of Port Neches, Nederland ...

Here's what we know about the Alien popcorn bucket. AMC Alien popcorn bucket AMC will release a facehugger bucket on Thursday, Aug. 15, according to an AMC employee.
Engineered Cementitious Composite (ECC), also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete, is an easily molded mortar-based composite reinforced with specially selected short random fibers, usually polymer fibers. [1]
