water hardening

基本解释

The material with high water is a new water-hardening inorganic gelling material. Its water-cement ratio is up to 3.0.
高水材料是一种新型水硬性无机胶凝材料，水灰比高达3.0。
Farmers think that using more nitrogen and potassium fertiliser will produce higher yields and this only leads to problems such as water pollution and hardening of the soil.
农民以为施用了更多的氮肥钾肥就可以得到更高的产量，这才带来了水体的污染、土壤的板结等问题。
Methods: According to their effects on the hardening depth and surface characteristic of the set materials, the water-hardening components, excipient vehicles, coagulation accelerators were selected.
方法：通过测定材料在水中的凝固速度及凝固后材料表面性状，对水硬性材料成份的种类、赋形剂的种类及凝固促进剂的种类进行筛选。
