Hydraulic Cement

Yes, hydraulic cement retains its expanded size once it's hardened. When the bread is baked, the larger size is permanently locked into place. The same thing happens with the hydraulic cement. And it happens fast usually within minutes. The Portland cement sets up and the larger volume of the mixture is locked in place permanently. Get price

Roman Surveying

Two learned Romans, Marcus Vitruvius Pollio, and Sextus Julius Frontinus, wrote of surveying practices in the Roman Empire at the time of Christ.

Roman concrete

Roman concrete, also called opus caementicium, was a material used in construction in Ancient Rome. Roman concrete was based on a hydraulic-setting cement. It is durable due to its incorporation of pozzolanic ash, which prevents cracks from spreading. By the middle of the 1st century, the material was used frequently, often brick-faced, although variations in aggregate allowed different arrangements of Get price

Roman Musical Instruments

However, the Romans successfully revived the barbiton where it is possible that it was indeed revived as an instrument of pleasure at parties and festive gatherings.

Building Roman Roads

The Romans preferred to build straight roads wherever possible and relied upon their surveyors to chart the route of their great highways. In most cases, the military would be responsible for plotting the route of new roads, but civil surveyors were used to survey courses for aqueducts, settle boundary disputes, and prepare the groundwork for buildings.

How concrete is made

Although the Romans had used hydraulic cement, the formula was lost from the collapse of their empire in the fifth century A.D. until Smeaton reinvented it. During the early nineteenth century several other Englishmen contributed to the refinement of synthetic cement, most notably Joseph Aspdin and Isaac Charles Johnson. Get price

Hydraulic mining

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits. Its modern form, using Get price
