Question

ayudaaaaa ,ROMAN ANCIENT CONSTRUCTION: Masonry construction

Brickmaking particularly in the region of Rome itself, became a major industry and finally, under the empire, a state monopoly Brick construction was cheaper than stone due to the economies of scale in mass production and the lower level of skill needed to put it in place. The brick arch was adopted to span openings in walls, precluding the need for lintels. Mortar was at first the traditional mixture of sand, lime, and water, but, beginning in the 2nd century BCE, a new ingredient was introduced. The Romans called it pulvis puteoli after the town of Puteoli (modern Pozzuoli), near Naples, where it was first found; the material, formed in Mount Vesuvius and mined on its slopes, is now called pozzolana. When mixed with lime, pozzolana forms a natural cement that is much stronger and more weather-resistant than lime mortar alone and that will harden even under water. Pozzolanic mortars were so strong and cheap, and could be placed by labourers of such low skill. that the Romans began to substitute them for bricks in the interiors of walls; the outer wythes of bricks were used mainly as forms to lay the pozzolana into place. Finally, the mortar of lime, sand, water, and pozzolana was mixed with stones and broken brick to form a true concrete, called opus caementicium. This concrete was still used with brick forms in walls, but soon it began to be placed into wooden forms, which were removed after the concrete had hardened. ese es el texto y las preguntad ay que contestarlas en simple past y no seeee:( A-WHAT IS THE TEXT ABOUT?
