Summary
Industrial waste like red mud (RM), blast furnace slag (BFS), and lime production waste (LPW) can stabilize natural loam (NL) for construction. The optimal mix meets construction material standards, reducing pollution and costs.
Area of Science:
- Materials Science and Engineering
- Environmental Science
- Civil Engineering
Background:
- Industrial waste poses environmental challenges.
- Utilizing waste in construction offers sustainable solutions.
- Soil stabilization with industrial byproducts is cost-effective.
Purpose of the Study:
- To develop eco-friendly construction materials using industrial waste.
- To stabilize natural loam (NL) with red mud (RM), blast furnace slag (BFS), and lime production waste (LPW).
- To assess the performance of stabilized soil for road base applications.
Main Methods:
- Preparation of nine different mixtures of NL, RM, BFS, and LPW.
- Characterization using X-ray diffraction (XRD), X-ray fluorescence (XRF), SEM, EDS, and AAS.
- Evaluation of axial compressive strength, water resistance, and frost resistance.
Main Results:
- Optimal mix: 40% RM, 35% BFS, 8% LPW, and NL.
- Achieved 7.38 MPa compressive strength (90 days), 7.12 MPa water resistance, 7.35 MPa frost resistance.
- Low linear expansion met Kazakh construction material standards; no heavy metals detected.
Conclusions:
- The RM, BFS, LPW, and NL mix is suitable for road base material.
- This application reduces environmental pollution from RM and BFS.
- The stabilized soil offers a cost-effective alternative for road construction.

01:22Waterproofing and Anti-Bacterial Admixtures in Concrete
111
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
