求翻译：由于充分发挥了水泥的活性，因此，允许较大量的填料（可以同时利用填料活性）替代水泥，仍可得到要求强度的混凝土，从而可以降低混凝土的成本。是什么意思？

As the full activity of the cement, thus allowing relatively large amount of filler (you can also use filler activity) instead of cement, can get the required strength of concrete, which can reduce the cost of concrete.

Because the active ingredients, and making the most of the cement, thus allowing a relatively large amount of fill material (You can also use fill reactive) Alternative cement, can still be called strength concrete concrete, thus they can reduce the cost.

Because had displayed the cement activeness fully, therefore, the permission massive padding (may simultaneously using padding activeness) substitute the cement, still might obtain the request intensity concrete, thus might reduce the concrete the cost.

Thanks to give full play to the cement activity and, therefore, allow more filler (activity while taking advantage of packing) instead of cement, you can still get required strength of concrete, which can reduce the cost of concrete.
