求翻译：低需水量的胶凝材料意味着可制造出低水胶比的混凝土，在此基础上如果再进一步提高胶凝材料的活性，则可得到胶凝材料需求量少而强度高的混凝土，因此，低需水活性胶凝材料的研制符合混凝土的发展趋势。是什么意思？

Low water demand can produce a cementitious material means low water-cement ratio of concrete, on this basis to further increase the cementitious material if the activity may be less demand for cementitious materials and high strength concrete, therefore, cementitious materials with low water activi

low volume of water required for the gel material means that can produce a low-water plastic than the concrete, on the basis of this if we further enhance gel material by reactive gel material, will receive low demand and high strength concrete, thus, the low-water-activated gel material required fo

The low water demand gel gelation gelling material meant may make the low hydrogel compared to concrete, in this foundation if further enhances the gel gelation gelling material again activeness, but then may obtain the gel gelation gelling material demand few the intensity high concrete, therefore,
