That alkalinity drops, however, as the concrete cures.

然而，随着混凝土固化，碱度会下降。

When you combine the emissions reduction during cement production with the CO2 consumption during concrete curing, we reduce cement's carbon footprint by up to 70 percent.

当您将水泥生产过程中的减排量与混凝土养护过程中的二氧化碳消耗量相结合时，我们最多可将水泥的碳足迹减少 70%。

What we're seeing when we put graphene into concrete is we get huge amounts of early strength - so we get very, very high tensile strength - in the first few days of the concrete curing.

当我们将石墨烯放入混凝土中时，我们看到的是我们在混凝土固化的最初几天获得了大量的早期强度——因此我们获得了非常、非常高的抗拉强度。
