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

主要由精选岩石组成，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" .

当产生富含晶体胶状物与骨料合时，该产品就是“生物”。

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

建筑工人在将颗与水和骨料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.

是粗石和组合，称为骨料，与水泥合，水泥是粘和石灰石粉末合物。

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。

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，方法是重塑作为其他成分骨料结合在一起方式。

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

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

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——，而我们仍在使用相同材​​料——水泥和骨料合物——因为改变阻力很大。
