Reduced embedded carbon. Post-tensioned stone causes the emission of <1/3rd of carbon dioxide greenhouse gas relative to concrete. [11] [18] Lower cost. A study of a 30-storey office block found that using PT stone floor panels was cheaper than concrete floors. [12]
After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold that may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish. After sufficient hardening, the surface is cleaned and generally sealed to provide protection.
A group of building experts published the Stone Tower Research Project showing that construction of a 30-storey skyscraper office block with a combination of an MP-stone load-bearing exoskeleton and post-tensioned stone flooring panels would cost less than the same building in concrete. [16]
The use of fly ash or another suitable substitute could theoretically bring CO 2 emissions below 0 kg/m 3, compared to Portland cement concrete emissions of 400 kg/m 3. The most effective method of production of this concrete would use the exhaust gas of a power plant, where an isolated chamber could control temperature and humidity.

Waste light is a form of polymer modified concrete. The specific polymer admixture allows the replacement of all the traditional aggregates (gravel, sand, stone) by any mixture of solid waste materials in the grain size of 3–10 mm to form a low-compressive-strength (3–20 N/mm 2) product [103] for road and
A litter of two-week old puppies was crammed into a bucket and abandoned alongside a road in Union County, New Jersey on Thursday, police said. The nine puppies were found...
