Abstract
The paper deals with the issues of technology of grouting binders of silicate materials with the use of waste from the processing of petroleum bituminous rocks. The optimal compositions of grouting solutions with the use of waste from the processing of PBR were studied.
The stability of the samples in aggressive environments of low-and high-base calcium hydrosilicates was studied. Technological processes for the production of grouting binders based on waste from the processing of PBR were justified and developed.
Grouting compositions, characterized by high quality were developed. The positive effect of mixing and storage of the tested cement mixtures containing up to 50% of PBR waste with sulfate solutions of Na 2SO 4 and MgSO4 salts on the studied technical characteristics of the grouting solution and cement stone was established.
A significant result is an improvement in the setting performance, an increase in strength without a significant deterioration in the adhesion of the cement stone to the drive pipe at a 5% salt concentration.
The research results provide recommendations for the development of weighted grouting cements using technogenic materials containing an increased amount of iron oxide.
