2. Polymer concrete - Wikipedia

   en.wikipedia.org/wiki/Polymer_concrete

   Unlike traditional concrete structures, polymer concrete requires no coating or welding of PVC-protected seams. [4] It can also be used as a bonded wearing course for asphalt pavement, for higher durability and higher strength upon a concrete substrate, and in skate parks, as it is a very smooth surface.

3. Bromoethane - Wikipedia

   en.wikipedia.org/wiki/Bromoethane

   Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.

4. IUPAC polymer nomenclature - Wikipedia

   In the example, there is a bromo-substituted -CH 2-CH 2 - subunit. 1-Bromoethane-1,2-diyl is chosen in preference to 2- bromoethane-1,2-diyl as the former has a lower locant for the bromo-substituent. The preferred CRU is therefore oxy(1-bromoethane-1,2-diyl) and the polymer is thus named poly[oxy(1-bromoethane-1,2-diyl)].

5. Living building material - Wikipedia

   en.wikipedia.org/wiki/Living_building_material

   The development of living building materials began with research of methods for mineralizing concrete, that were inspired by coral mineralization.The use of microbiologically induced calcite precipitation (MICP) in concrete was pioneered by Adolphe et al. in 1990, as a method of applying a protective coating to building façades.

6. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   In poured concrete foundations, cracks and pipe penetrations are the most common entry points for seepage. These openings can be sealed from the interior. Epoxies , which are strong adhesives, or urethanes can be pressure injected into the openings, thus penetrating the foundation through to the exterior and cutting off the path of the seepage.

7. Polyaspartic esters - Wikipedia

   [4] [5] These products are then used in coatings, adhesives, sealants and elastomers. [6] Pure polyurea reacts extremely quickly making them almost unusable without plural component spray equipment. Polyaspartic technology utilizes a partially blocked amine to react more slowly with the isocyanates and thus produce a modified polyurea .
