Improving the Properties of Arthma Sand for Using In the Sand Moulding
Engineering and Technology Journal, 2005 The aim of the present research is to improve properties of Arthma sand through the addition of different materials for using it in sand casting processes. After preparing the master mixture from (Arthma sand, 5% Bentonite, 5% water), then we add different percents ranging between (2-8)% of the added maters which were phenol, phenol with Boric acid ...

Energy Science &Engineering, EarlyView.This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...
