1. I-Qilu grey granite inobuningi besakhiwo, amandla aqinile aphezulu, ukumuncwa kwamanzi aphansi, ubulukhuni obuphezulu bomhlaba, ukumelana okuhle kwamakhemikhali, ukuqina okuqinile, kodwa i-flame retadancy embi.
2. I-Qilu grey granite inesakhiwo esiyimbudumbudu esicolekile, esimaphakathi, nesihlabathi, noma isakhiwo esimagqabhagqabha.Izinhlayiya zayo zifana futhi zintekenteke, zinezikhala ezincane (i-porosity ngokuvamile i-0.3% ~ 0.7%), ukumuncwa kwamanzi okuphansi (ukumuncwa kwamanzi ngokuvamile ku-0.15% ~ 0.46%), nokumelana nesithwathwa okuhle.
3. Itshe le-limestone le-Qilu legwadle linobunzima obukhulu.Ukuqina kwe-Mohs cishe ku-6, futhi ukuqina cishe ku-2. 63g/cm3 kuya ku-2.75g/cm.Amandla ayo ebhondi yi-100-300MPa.Phakathi kwazo, umthamo wegranite yesihlabathi esihle ungafika ku-300MPa.Amandla okugoba ngokuvamile angu-10-30Mpa.
