The present disclosure may relate to a method of remediating a wellbore. The method may comprise pumping a resin treatment fluid from a surface location to an annular space bounded by an outer diameter of a production tubular, wherein the resin treatment fluid comprises a liquid hardenable resin, a hardening agent, and a particulate bridging agent. The resin treatment fluid may gravity settle in the annular space to contact production equipment in the annular space such that at least a portion of the particulate bridging agent bridges across one or more damaged sections of the production equipment, wherein at least a portion of the liquid hardenable resin sets to form a hardened mass to seal the one or more damaged sections.

Efflorescence resistance of concrete blocks is enhanced through the use of glass powder in the concrete composition. The glass powder permits a reduction in the cement content; the glass powder also creates a pozzolanic reaction to change the free calcium ions in calcium hydroxide to calcium silicate to fix the calcium ions inside concrete. The composition includes cementitious binding material of ordinary Portland cement, fly ash, calcium sulfoaluminate cement, ground-granulated blast-furnace slag in an amount from 20 to 25 wt. %. Coarse aggregate is provided from 10 to 15 wt. percent. Fine aggregate is from 32 to 39 wt. %. The composition further includes glass powder having a diameter of less than approximately 75 microns in an amount from 17 to 23 wt. %. Water is present in an amount from 6 to 9 wt. %. The dry density of formed paving blocks is 1800-2200 kg/m.sup.3.
