The secret of the ancient Roman people 's concrete

There is a fact to admit that ancient Roman people could create concrete better than what we have now. Modern buildings began to be degraded after about 50 years or faced with environmental problems, while Roman buildings still remained solid after hundreds of years.

Scientists have been studying how to make ancient Roman concrete to be able to find solutions for modern buildings to increase durability - at the same time less harmful to the environment.

To create a super-hard concrete, the ancient Romans mixed lime with volcanic rock.'For underwater works, lime and volcanic ash mixed together to form a mortar, this mortar will be combined with volcanic rock and put into wood molds'. 'Seawater will immediately create a chemical reaction that radiates heat. Hydrated lime - combines water molecules into its structure - and reacts with volcanic ash to link all the mixes together ' , according to information from a press release of the alliance. international scientist.

More impressively, the Roman concrete makes less carbon emissions and still has very high durability. Today, cement types account for about 7% of carbon dioxide emissions harmful to the environment every year. According to the ancient Roman concrete production method, it takes more time for the mortar mixture to harden than the modern method, however, for a large project, durability is the most important thing, because so there will be a lot of things that scientists can take advantage of from studying the ancient Roman people 's concrete.
