Abstract
A method of increasing the strength of a carbonate rock is described. The carbonate rock may be located within a subterranean carbonate formation or may be located on a building exterior. The method involves contacting the carbonate rock with a composition comprising a zinc salt or a silicon alkoxide. This may increase the hardness of the carbonate rock by 10% or more.
Claims14
A method for treating a carbonate rock, comprising:
- contacting the carbonate rock with an aqueous composition comprising 0.01-1.0 M zinc salt, wherein the contacting is maintained for a time period of 12-72 h, thus forming a treated rock having a hardness determined by Young's modulus that is at least 10% greater than the carbonate rock.
