求翻译：活性水泥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？

Activity of cement as the cement of full activity, 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.

Reactive cement since they played the cement the reactive, therefore, allow a relatively large amount of fill material (You can also use alternative cement, fill reactive) may still be required, thus allowing it to reduce strength concrete Concrete cost.

Because the active cement has 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.

Activity cement 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.
