对一种无机锚进行了系统的试验研究。其锚固剂是一种特种水泥，固化速度快，终凝时间在7 min以内，1h内抗压强度可达19.2MPa。锚栓与水泥之间的粘结强度达到110 kg/cm 2，水泥与岩石或煤体之间的粘结强度也达到47 kg/cm 2。锚栓早期拉力较大，安装1h后拉力达14 t。这种锚栓具有制作简单、造价低廉、安装方便等优点，适用于各种工程问题。
A kind of abiochemistry anchor bolt was studied by a series of systematic tests. Its anchorage agent is a kind of special cement that cures quickly with the final setting time within 7 min, and compressive strength of the special cement can reach 19.2 MPa within 1h. The glutinous strength between the anchor bolt and the cement reaches 110 kg/cm2, and the glutinous strength between the cement and the rock or coal mass also reaches 47 kg/cm2. Early tensile force of the anchor bolt is high, which amounts to 14 ton after installed 1h. This kind of anchor bolt can be made simply and cheaply, installed conveniently and applied to different engineering problems.
