英语翻译
However,the manufacture of cement used for concrete
uses vast amounts of energy and produces a great deal of
pollution,to the extent that many designers choose not to
use the material because of the environmental harm that
it causes.If used in large quantities in a structure],though,
this damage may be off set by the thermal store effect of
the mass of concrete which helps to regulate temperature.
Considered over a period of at least 15 years (depending
on the installation),this can off set energy used during
manufacture.
然而,制造用于混凝土中的水泥需要大量的能量,并且产生大量的污染,以至于许多设计者出于其对于环境的伤害程度而不愿使用这种材料.如果将其大量的用于建筑结构中,尽管这种危害会被大量的、用于调节温度的混凝土的热储存效应抵消掉,但是需考虑到这至少需要15年的时间(由施工情况决定)才能抵消掉制造过程中使用的能量.
