Use of magnetic water application of concrete engineering, now still don’t cheap and efficient measuring the level of magnetization of magnetic water method, and it is therefore hard to control the quality to concrete.
Therefore, this study utilizes Hall voltage produced in the process of magnetization as the monitoring indices of magnetic water at once.
A preliminary study in search of stable measure Hall voltage method, and further water flow rate affect the Hall voltage, finally observe basic character of magnetic water, and Hall voltage compressive strength of mortar, flow value, and time setting of relationship.
The result of the study indicates that stable Hall voltage can be measured by tube of electric conduction、long electrode、plus capacitance and circulating water, but
Reproducibility else don't satisfy.
Aggrandize to Water flow rate increases Hall voltage ,but build meaningful relation of statistics off the map.
Use of magnetic water can abbreviate time setting of hydraulic cement, increase compression of hydraulic cement mortars, and reduce to
flow value of hydraulic cement mortars.

還好你有寫一些英文, 我已經盡量去了解你的意思, 因為我中文不是很好. MSN線上歐洲的朋友說我瘋了, 怎麼會花時間撿這種沒人要做的, 我就是看你已連發2次求助問題, 又沒人回答, 才幫你看看嘛... 是花了點時間~
hydraulic cement mortars 你到底是 "砂漿" 還是 "水泥漿" 看待??還是都是一樣的東西???
In applying magnetic water into concrete engineering, there isn't any cheap and efficient way to supervise the level of magnetization of magnetic water currently. Therefore, it's hard to control the the quality to concrete.
This research temps to take Hall voltage produced in the process of magnetization as the monitoring indicator of magnetic water.
The preliminary research starts in searching for methods that enable to measure the Hall voltage stably, furthermore, how water amount and its flow speed affect the Hall voltage. At the end, observe the character of magnetic water, and the relationships of the Hall voltage against compressive strength of mortar, its flow data, and clouted time setting.
The research indicates that stability of the Hall voltage can be measured with tubes of electric conduction、long electrode、plus capacitance and circulating water, however, the reproducibility is not satisfied.
Aggrandizing water amount and its flow rate increases the Hall voltage, but the statistics is meaningless.
Use of magnetic water can shorten the time of hydraulic cement, increase compression of hydraulic cement mortars, and reduce the flow measurement of hydraulic cement mortars.
