INFLUENCE OF NANOADDITIVES ON MECHANICAL AND ISOLATING PROPERTIES OF CEMENT-BASED COMPOSITIONS
The results of the laboratory and field tests performed to study aminoetaksiaerosil-based cement compositions with nanoadditives are presented. It has been shown that mechanical and isolating properties of the slurry are improved when nanoadditives are introduced. After 48-hours hardening bending strength of cement stone increases by 15%, and waterproof effect - by 60%. The remedial cementing success of cement slurry without nanoadditives is 45-50% and of the cement slurry with nanoadditives is 75%. The aminoetaksiaerosil addition rises dispersion degree for newgrowths formed during cement rehydration process that results in a higher mechanical strength of the mudding degree, which causes penetration capacity and watered stratum filling factor increase.
