Development of a production technology for a high-strength, high-bearing-capacity deep foundation using a complex modified additive based on industrial waste
A new variable-profile pile foundation and an improved concrete composition.
Details
Funding programme
Grant funding competition for scientific and/or scientific-technical projects for 2023–2025, Ministry of Science and Higher Education of the Republic of Kazakhstan.
Relevance
The project addresses high material consumption, limited bearing capacity and durability of conventional deep foundations. A large share of foundations in Astana and other Kazakh cities are deep foundations, mainly precast driven piles. The proposed variable-profile pile rotates successive sections relative to the symmetry axis to improve soil resistance. A complex modified admixture based on soapstock, post-alcohol distillers’ grains, microsilica and phosphogypsum was also developed to improve concrete strength, hydrophobicity and durability while utilizing industrial waste.
Objective
To develop a competitive deep-foundation production technology combining a new structural solution with an improved technological composition.
Expected and achieved results
- Research programs and implementation conditions were prepared.
- Geotechnical studies, limit-state calculations and numerical modelling were completed, including comparative model-box tests against conventional piles.
- Foundation materials and the properties of sand, crushed stone, cement and modified-additive components were investigated.
- A working technological composition for deep-foundation production was developed.
- Scientific papers were published and two IP documents were obtained, as listed below.
- Construction and installation of a pilot production site/technological line was planned.
- A program of static compression, uplift and integrity testing of pilot foundation specimens was planned.
- The archived project text also lists planned Scopus/Web of Science publications, a Kazakhstan patent application, a work-production plan and technical regulations.

Information for potential users
The variable-profile pile is intended to provide about 10–30% higher bearing capacity, depending on soil conditions, at comparable material consumption. Improved strength and other physical-mechanical properties are supported by a specially developed modified additive for structures subjected to high impact loads.
