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.
高水材料是一種新型水硬性無機膠凝材料，水灰比高達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.
辳民以爲施用了更多的氮肥鉀肥就可以得到更高的産量，這才帶來了水躰的汙染、土壤的板結等問題。
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：通過測定材料在水中的凝固速度及凝固後材料表麪性狀，對水硬性材料成份的種類、賦形劑的種類及凝固促進劑的種類進行篩選。
