Abstract
When extracting petroleum during the drilling and exploration process, large
quantities of sand are left behind from petroleum wells. This sand is often mixed with
drilling fluids containing environmentally harmful substances.
Many international organizations have recognized the danger of these sands,
prompting oil-producing countries to take measures and enact strict laws to deal with
this issue. Several global research studies propose various solutions, including the
possibility of using heat to extract harmful chemicals and then disposing of the treated
sands as non-contaminated.
It is known that treating these sands with heat, reaching temperatures up to 500
degrees Celsius, can alter many of their chemical and physical properties. The
question arises: can we use these heat-treated sands in construction in general, and
specifically as a binding material?
When using heat-treated petroleum well sands as a 100% binder, we achieve a
bending resistance of 1.50 MPa and a compressive strength of approximately 0.8 MPa
after 28 days. These properties improve as we add a considerable percentage of CaO,
considered as clinker. When using a mixture of 50% cement and 50% heat-treated
petroleum sands, the bending resistance at 28 days improves to 2.23 MPa, and the
compressive strength increases to 4.8 MPa. Further improvement is observed when
increasing the cement ratio to 70%, resulting in a bending resistance of 4.05 MPa and
a compressive strength of 6.8 MPa after 28 days.
106In conclusion, the heat-treated petroleum sands show promising potential for use in
construction, especially when combined with cement, offering improved mechanical
properties
