Abstract
Cements, such as alkali activated binder, may be used as coatings on proppants, such as sand, to improve the strength thereof. The resulting chemically bonded phosphate ceramic (CBPC) coated proppants show increased compressive strength between about 60 to about 130 MPa, as well as produced fines of lower than about 10 wt % at 10,000 psi closure stress.
