Cement compositions for well cementing operations comprise an isocyanate compound and solid particles. The solid particles are present in at least three distinct particle size groups. The compositions may further comprise a blocking agent and solvents such as polyols, hydrocarbon solvents, diesel or water. The compositions are particularly useful in the context of remedial cementing, which may be squeeze cementing or plug cementing.
