HIGH POTENTIAL CONSTRUCTION MATERIALS BASED
ON PETROLEUM WASTES
Abstract. This article presents the description of production processes of soil-concrete mixtures using petro-
leum wastes (petroleum-contaminated soils). Physicochemical and mechanical properties of petroleum-contaminated
soils and soil-concrete samples have been researched. These products can be used for construction of bottom and top
beds of highway and airport foundations as well as for ground stabilization.
Key words: soil-concrete, petroleum wastes, petroleum-contaminated soils (PCS), road construction.
1. Introduction. The problem of disposal of petroleum wastes accumulated as a result of activities of
oil and gas enterprises has become very important these days first of all because of increased production
volumes of petroleum industry. Development of effective ways of utilization will make possible con-
version of hazardous wastes into valuable and safe products. It is a known fact that the drilling of oil wells
leads to a severe contamination of soil and ground water with drill cuttings containing hydrocarbons,
heavy metals and polymers, and that spilling of oil during production is associated with negative
occurrences leading to devastation of soil and petroleum contamination of massive land areas. Oil wastes
and petroleum-contaminated soils cause significant damage to environment [1, 2].
The most promising way to solve these problems is development of new technologies able to reclaim
environment by using wastes to enhance quality of construction products. The wastes contain water and
components that can increase the quality or partially replace expensive bitumen in asphalt concrete.
Petroleum-contaminated soil may be considered as non-expensive road construction material that can be
used for construction of frost blankets of roads and sidewalks as well as soil stabilizer in oil pipeline
construction.
Research literature these days pays considerable attention to the issue of the use of local raw mate-
rials in production of new versions of concrete and soil-concrete. It is a known fact that cheap material
leads to a cheaper end product. In our research, according to the present requirements, use of local
Kazakhstani raw materials and wastes in production of soil-concrete and cement concrete is very impor-
tant matter. The research utilized petroleum-contaminated soil obtained from Zhanauzen oilfields, marble
cuttings from Mangistau region, different slags, brick pieces, asbestos wastes, pieces of glass and indus-
trial wastes from Khromtau in Aktobe region[3-5].
The purpose of the research is development of technology of production of soil-concrete mixtures
based on available and affordable raw materials – petroleum industry wastes, examination of physico-
chemical properties to define the most promising areas of their practical use.

2. Materials and Methods. Soil-concrete was prepared in the following way: petroleum-con-
taminated soil 30-55% by mass was mixed with Portland cement (15% by mass), sand 25% by mass, lime
5% by mass, industrial-construction wastes 30% by mass (tiles, shells, bricks, marble) in a mixer. Then
water was added and the mixture was mixed to make homogenous grout.
Then mixture was poured into a mould and compacted with a metal stick or vibrator, which can be
used when the mixture had a liquid or semi-liquid consistency.
Q-1000/D MOM (Budapest) derivatograph designed by F. Paulik, J. Paulik and L. Erdey was used
for thermal analysis of the tested sample. The data was collected in air environment at 20-1000

3. Results and Discussion. We researched the composition and structure of raw material (petroleum-
contaminated soil) to be used for production of soil-concrete.
Physicochemical properties of petroleum-contaminated soil obtained from Zhanauzen were determi-
ned by the way of IR spectroscopy (Figure 1). 1250 cm

X-ray diffraction analysis of Zhanauzen petroleum-contaminated soil showed different minerals
besides organic substances. Interpretation of X-ray diffraction analysis with the use of international
reference materials showed such basic minerals as feldspars, serpentines, calcites.
Figure 2 shows that Zhanauzen petroleum-contaminated soil contains 30% of carbon atoms, 65% of
oxygen atoms, mineral substance include 0.25-1.51% of magnesium, calcium, aluminum, silicon as salts
and oxides.
Figure 2 – X-ray diffraction analysis and chemical composition
of Zhanauzen petroleum-contaminated soil
Several samples of soil-concrete were prepared with the use of different construction wastes.
Zhanauzen petroleum-contaminated soil was used along with construction wastes such as tiles, slags,
bricks, shells, asbestos and glass pieces. Use of these materials in concrete production reduces the costs
and helps in saving natural resources. The use and utilization of these wastes helps environmental protec-
tion.These concrete products can be used in road construction (sidewalks, highway beds) and in civil
engineering.
Electron-microscopic analysis of the samples of soil-concrete was done with a scanning electron
microscope (JEOL JSM – 6390 LV, JED 2300) and structural image was received at 10, 100 и 500 μm.
Figure 3 shows microstructure of the soil-concrete received with a scanning electronic microscope. It
is possible to track the morphology of the soil-concrete surface using these pictures with different
magnification of concrete particles.
Processing of the data defines the following:
1. Size of the particles from 20 to 400 μm
2. Particle structure – porous
3. Chemical composition, % by mass: carbon - 7.55; oxygen - 29.64; calcium-43.56; sodium - 0.33,
aluminum - 2.15, magnesium - 0.70, sulphur - 2.99, silicon - 13.09 and small amount of phosphorous.
In the sample, in which the shells were used, the isolated isometric, sometimes oval pores were
found (Figure 3). There are also few oval-shaped big pores (up to 40 μm) and isometric pores of “channel”
type. It would seem that these pores are responsible for water adsorption.
Like all of tested soil-concrete samples, the sample with added glass pieces (Figure 4) has porous
uneven structure with scarce inclusions of filler particles. Virtually ideal spherical shape of glass particles
can be seen, which has a positive impact on physical and mechanical properties of composites. Glass
pieces and fragments of big spheres can be also seen. Amorphous nature of glass bound by cement grout
with mineral material provides strong structure resulting in better mechanical properties of soil-concrete.
In the samples with added ash and slag wastes, narrow slot-like pores as well as groups of connected
irregular pores were found (Figure 5). There is also small quantity of isometric closed pores but they are
relatively insignificant for the general structure porosity. Slot-like pores normally are bent, crescent-
shaped but some straight pores can also be seen. Availability of small cells in the structure provides good
insulating properties of concrete.
X-ray diffraction analysis of soil-concrete sample (Table 1) was done on D8 Advance (Bruker), α-Cu,
40 kv tube voltage, 40 mA current. EVA software was used for processing of diffraction patterns and cal-
culation of planar spacing. Search/match software was used for interpretation and phase searching based
on PDF-2 powder diffractometric Database. The following minerals were defined.

Differential thermal and thermal gravimetric analysis resulted in definition of sample thermal
behavior and it’s elemental composition (Figure 6). Thermal chemistry parameters of the tested sample
showed approximate resemblance to the composition and thermal chemical properties of standard
concretes.
Interpretation of differential thermal and thermal gravimetric curves of tested sample showed
(directly and indirectly) presence of siliceous rocks (quartz, feldspar, potassium feldspar), carbonate
minerals (as calcite (14.7%) and magnesite (<1%)with the traces of iron oxides and calcite. Several links
of molecular (Н

О) and hydroxyl (OH) water were found among above formations. As well as carbon
dioxide in gaseous state resulting from dissociation of СаСО

Figure 6 – Thermogram ofsoil-concrete sample
Most of molecular and hydroxyl water (~90%) was added during the mixing of soil-concrete, and
only a little portion of hydrates (<10%) was the part of the components structure. The most illustrative fact
proving water presence in the sample body would be prominent endothermic peaks on DTA and DTG
curves found at 90 and 400

The most intensive thermal reactions out of all registered during the test is the one in high tempe-
rature range. It was a result of calcium carbonate dissociation into CaO andСО

the system has the weight loss of Δm

and amount of lost carbon dioxide, the
content of calcite in the sample is 14.7%.
There is also some (0.5%) magnesite found due to slight dip of DTG curve at 430-575
о
С. In this
temperature range, the weight loss is 0.5%, 0.25% of which is due to СО

Presence of quartz and Si, Ca, Mg, Feoxides was defined by blurred peak of polymorphic transfor-
mationα-SiO

The test date (Table 2) showed good compressive strength of water saturated samples aged for 28
days equal to 5,52-3,05 MPa, tensile bending strength of 2,25-3,05 MPa.

4. Conclusion. Based on the above figures, one can conclude that soil-concrete mixtures have wide
potential use. They can be used for bottom and top layers of highway and airport pavements, soil reinfor-
cement during the construction of pipelines. Stabilization of industrial wastes with the help of cementing
material increases opportunities of the use of soil-concrete, allowing vast stocks of widespread environ-
ment-threatening wastes to be utilized.
