water hardening

基本解釋

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(wú)機(jī)膠凝材料，水灰比高達(dá)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.
農(nóng)民以為施用了更多的氮肥鉀肥就可以得到更高的產(chǎn)量，這才帶來(lái)了水體的污染、土壤的板結(jié)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(cè)定材料在水中的凝固速度及凝固后材料表面性狀，對(duì)水硬性材料成份的種類、賦形劑的種類及凝固促進(jìn)劑的種類進(jìn)行篩選。
