他一直在跟着我。

A series of laboratory cementing experiments on the total tailings from a gold mine in Shandong Province were conducted by use of ordinary cement and polyhydrate material as binding materials.

摘要分别采用普通泥和高单浆料为胶结材料对山矿全尾矿进行了胶结对比试验。

The results indicated that the polyhydrate binding material can produce higher binding strength under lower dosage compared with the ordinary cement, so it is applied to cement total gold tailings.

结果表明，高单浆料与泥相比具有用量少、试块早期强度高的特点，适用于矿全尾胶结。
