求翻译：随着减水剂掺量的增大，存在着一个使水泥的比表面积比基准水泥小，筛余比基准水泥大的掺量，此时减水剂掺量处在助磨性最佳掺量范围内，如水泥2所示。另外，水泥4与基准水泥相比，其比表面积显著减少，筛余显著增大，其性能发生了显著变化，此时减水剂掺量处在超临界掺量范围内。显然，在助磨性掺量与超临界掺量之间存在一个临界掺量，即在此掺量下，水泥性能与基准水泥相比，已经发生了一些变化，但不显著。是什么意思？

With superplasticizer dosage increases, there is a specific surface area than the cement base cement small, sieve larger than the ash cement base, this time in a grinding aid dosage of superplasticizer dosage best range, such as cement 2. In addition, the cement base cement, compared with 4 of its s

With a reduction of the increased volume mixing water agent, there is a benchmark for cement 105-150cement than small, sieve residue than the benchmark cement mixing of volume reduction at this time, the volume mixing water agent grinding of the best mixed with volume, such as cement within 2 below.

Mixes the quantity along with the water reducing agent enlargement, has one to cause the cement to be smaller than the table area ratio datum cement, the triage big mixes the quantity compared to the datum cement, this time the water reducing agent mixes the quantity to occupy helps rubs the nature

As superplasticizer content increases, have a cement of small specific area than the base cement, screenings than the base cement admixture, superplasticizer admixture in grinding with best of volume within as shown in cement 2. In addition, cement 4 compared with the base of cement, the specific su
