ABSTRACT
Considered the creation of cement materials for the attachment of high-temperature wells. Traditional Portland cement cannot be used at temperatures above 100 ° C due to thermal corrosion of hardening products due to interphase and intra-phase recrystallization, while the permeability of the cement stone significantly increases. The results of laboratory studies of heat-resistant cements obtained using cement slag-based materials are given. The physic-mechanical and strength properties of slag sand mixtures were investigated. The phase composition of the hardening products of cement materials was investigated by X-ray analysis. High thermal resistance of cement stone was obtained.
