Concrete consists largely of a selection of rocks, known as aggregates.

混要由精选岩石组成，这些岩石被称为骨料。

Bioconcrete actually comes in many varieties, depending on the aggregate employed.

生物混实际上有很多种，具体取决于所使用骨料。

Meanwhile, while asphalt also  features aggregates like concrete, it has a different binding agent.

同时，虽然沥青也像混一样具有骨料特征，但它具有不同粘合剂。

When the crystal-rich gloop that results is mixed with an aggregate, the product is " bioconcrete" .

当产生含晶体胶状物与骨料混合时，该产品就是“生物混”。

Construction workers pour the pellets into conventional cement when mixing it with water and aggregate.

建筑工人在将颗粒与水和骨料混合时将其倒入传统水泥中。

Concrete is a combination of coarse stone and sand particles, called aggregates, that mix with cement, a powdered blend of clay and limestone.

混是粗石和沙粒组合，称为骨料，与水泥混合，水泥是粘和石灰石混合物。

Better, then, not to generate it in the first place, by remodelling the way the aggregates that are concrete's other ingredient are bound together.

那么，最好不要首先生成它，方法是重塑作为混其他成分骨料结合在一起方式。

When water gets added to this mix, the cement forms a paste and coats the aggregates, quickly hardening through a chemical reaction called hydration.

当向这种混合物中加入水时，水泥会形成糊状物并覆盖在骨料上，通过称为水合作用化学反应迅速硬化。

Aggregates account for between 60 and 75% of a given concrete mix, and are bound together  with a paste, which makes up the remainder.

骨料占给定混混合物 60% 到 75%，并与浆料粘合在一起， 其余部分由浆料粘合。

A lot of the medieval buildings that are near the coast, the mortars are formed with aggregate taken from the beaches – so, crushed shell, crushed oyster shell, cockle shell.

许多靠近海岸中世纪建筑，其迫击炮灰都是用从海滩上采集骨料制成——碎贝壳、碎牡蛎壳、碎贝壳。

They've been doing the same material - concrete  - since Roman times and we're still doing it the same - a cement and aggregate mix - because  there is a lot of resistance to change.

自罗马时代以来，他们一直在使用相同材​​料——混，而我们仍在使用相同材​​料——水泥和骨料混合物——因为改变阻力很大。
