Structural and heat insulating foam concrete made with drill cuttings

The article presents the results of drill cuttings effect upon the properties of cement foam concrete mix and naturally cured foam concrete. Drilling cuttings (a by-product of oil extraction) are suggested to be used as a fine aggregate for constructive and heatinsulating foam concrete for the development and construction of oil and gas fields. The replacement of silica sand with cuttings will address the problem of resources for producing non-autoclaved foam concrete with high-quality fine aggregate at field development sites, and also utilize drilling cuttings as a waste product. Partial or complete replacement of sand with drill cuttings in the technology of non-autoclaved foam concrete allows to increase the compressive strength of the latter at the age of 28 days. The research was carried out in the accredited Stromtest testing laboratory of the Tomsk State University of Architecture and Civil Engineering. The developed composition of cement foam concrete is recommended for the construction of cast-in-situ walls at the construction site or for the manufacture of prefabricated wall blocks for individual housing construction.
