2. Expanded polystyrene concrete - Wikipedia

   en.wikipedia.org/wiki/Expanded_polystyrene_concrete

   It is created by using small lightweight EPS balls (sometimes called Styrofoam) as an aggregate instead of the crushed stone that is used in regular concrete. [3] It is not as strong as stone-based concrete mixes, but has other advantages such as increased thermal and sound insulation properties, easy shaping and ability to be formed by hand ...

3. Foam concrete - Wikipedia

   en.wikipedia.org/wiki/Foam_concrete

   A cylinder of foam concrete. Foam concrete, also known as Lightweight Cellular Concrete (LCC) and Low Density Cellular Concrete (LDCC), and by other names, is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. [1]

4. Filigree concrete - Wikipedia

   en.wikipedia.org/wiki/Filigree_concrete

   Subsequently, the deck's top reinforcing steel is placed on top of the precast panels at the site, and concrete is poured over the entire assembly to achieve the final thickness of the deck. This process effectively accelerates the construction of structures by eliminating the need for costly and time-consuming field forming, and the placing of ...

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   PMMA ignites at 460 °C (860 °F) and burns, forming carbon dioxide, water, carbon monoxide, and low-molecular-weight compounds, including formaldehyde. [ 17 ] PMMA transmits up to 92% of visible light (3 mm (0.12 in) thickness), [ 18 ] and gives a reflection of about 4% from each of its surfaces due to its refractive index (1.4905 at 589.3 nm ...
