The paper presents the results of studies of the possibility of utilization of petroleum sludge, obtained during the purification of oil-water emulsions, using gabbro-diabase powder in the production of ceramic building products. The sludge is proposed to add to the clay mass as an entrained additive. The influence of the sludge additive mass on such physical and mechanical indicators of ceramic samples, as density, compressive strength, water absorption, air shrinkage and fire shrinkage, and density, is studied. Ceramic samples were prepared using natural clays, deposits Bessonovka (Belgorod region) and Podgornoye (Voronezh region). It is shown that the addition of 2% mass to the clay mass of the sludge leads to an increase in the compressive strength of the samples up to 90%, an air shrinkage of 1%, an increase in water absorption 1-2%. The value of the fire shrinkage remains unchanged. With an increase in the proportion of sludge additive to 7%, all indicators slightly change. Water absorption and air shrinkage increase, compressive strength, fire shrinkage and density decrease. However, further, when there is 7% of sludge in the clay mixture, the strength of ceramic samples corresponds to a grade not lower than 150, according to GOST 530-2012.

The paper presents the results of a study of the possibility of recycling water treatment sludge in the production of wood-cement composites. Sludge is formed during the treatment of sewage, containing industrial machine oil, with a sorption material, based on thermally modified chestnut tree waste (CTW). It was found that the addition of sludge leads to an increase in the density of the samples. Thus, the samples without the addition of sludge have an average density of 860 kg/m3, samples with the addition of sludge in an amount of 10 mass% - 875 kg/m3, 20 mass% - 879 kg/m3, 30 mass% - 882 kg/m3, 42 mass % - 887 kg/m3. Studies of the change in water absorption of samples, depending on the amount of sludge added, showed that the values slightly decrease for samples containing sludge, what is explained by the presence of oil in the mixture. The compressive strength of the samples with the addition of sludge in the amount of 42 mass% was 3.1 MPa, what corresponds to the regulatory requirements for a wood cement composites.

In the paper, the influence of mullite wool waste additive on the properties of building ceramics is analysed. For that purpose four formation masses were prepared, dried and fired at the analogous regimes (maximum firing temperature 1080 °C). The fired samples were used to determine the structural and physical-mechanical properties. The values of these parameters are analysed: water absorption, total and effective porosity, rate of capillary mass flow, reserve of porous volume, compressive strength, density and estimated exploitation frost resistance. It has been determined that mullite wool waste can be applied to the production of building ceramics and the optimum quantity of waste in a formation mass is 10 % according to weight. Water absorption of those ceramic samples was less than 4 %, compressive strength was 28.6 MPa, density - 2033 kg/m3, forecasted resistance to frost about 400 cycles.http://dx.doi.org/10.5755/j01.ms.17.1.255

Water Treatment Plant Sludge

In this study, an attempt was made to use water treatment plant (WTP) sludge and dam sediment as raw materials for brick-making through the sintering process. The sinter of dam sediment fired at 1,050°C had a less than 15% ratio water absorption, and its compressive strength and bulk density met the Chinese National Standard (CNS) for first level brick. The WTP sludge sinter made under the same operating condition exhibited higher water absorption, larger shrinkage, but poorer compressive strength. When fired at 1,100°C, the shrinkage of the WTP sludge sinter was as high as 45%, although its compressive strength and water absorption of WTP sludge brick still met the standard for the first level brick. To reuse WTP sludge in an economical way, mixtures of various proportions of WTP sludge to dam sediment are used as raw materials. A satisfactory result was achieved when the ratio of the WTP sludge was less than 20% of the mixture. Results of tests indicated that the sinter of dam sediments which are fired at a temperature of 1000~1100°C has reached the requirement for tile brick.

And Performance

Every year, large quantity of water treatment sludge (WTS) is produced from water treatment plant in Malaysia. Sanitary landfill disposal of sludge at authorized sites is the common practice in Malaysia. However, searching the suitable site for landfill is the major problem as the amount of sludge produced keeps on increasing. Reuse of the sludge could be an alternative to disposal. This study investigated the reusability of WTS as brick making material. The performance of clay-WTS bricks produced by mixing clay with different percentages of WTS with increments of 20% from 0% up to 100% was investigated. Each molded brick with optimum moisture content was pressed under constant pressure, oven-dried at 100˚C for 24 hours followed by heating at 600˚C for 2 hours and 1000˚C for 3 hours. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray (EDX) analysis were used to characterize clay, WTS and clay-WTS bricks.  The performance of the bricks were evaluated with firing shrinkage, loss on ignition (LOI), water absorption, bulk density, and compressive strength tests. Increasing the sludge content results in a decrease of brick firing shrinkage, and increase of water absorption and compressive strength. The results revealed that the brick with 100% by weight of sludge could generate the highest compressive strength of 17.123N/mm2. It can be concluded that the bricks with 20 to 100% of water treatment sludge comply with the Malaysian Standard MS7.6:1972, which can fulfill the general requirement for usage of clay bricks in wall construction.

Leaching Behaviour

In Malaysia, the current practise in treatment of petroleum sludge (PS) is by using incineration and the ash produce required further treatment for safely disposal into landfill. This process require high cost and treatment of raw sludge by using solidification/stabilization method was introduce. In this study, ordinary Portland cement was used as binder. This study focuses on physical properties (compressive strength, density test and water absorption) of S/S matrices and leaching behaviour (SPLP). Results shows adds up to of 30% PS gives results on strength which comply with minimum landfill dispose limit. Correlation between strength and density in regression coefficient of 80.99% and correlation between strength and water absorption shows strong regression of 93.12%. Leaching behaviours on 28 th day of curing showed the similar trend as on 7th day of curing. All heavy metals concentration in leaching test were below the USEPA standard except for Nickel and Chromium. Even though these two metals were exceeded the standard, Portland cement was capable to encapsulate Ni and Cr in mixture and reduce the concentration of 87% and 69% (PS 40%), respectively, compare to concentration in raw sludge. As, conclusion S/S method can be an alternative disposal method for raw sludge.

This work reports on the incorporation of Flint and Kaolin rocks powders in the cement mortar in an attempt to improve its mechanical properties and produce an eco-friendly mortar. Flint and Kaolin powders are prepared by dry mechanical milling. The two powders are added separately to the mortars substituting cement partially. The two powders are found to improve the mechanical properties of the mortars. Hardness and compressive strength are found to increase with the increase of powders constituents in the cement mortars. In addition, the two powders affect water absorption and thermal conductivity of the mortar specimens which are desirable for construction applications. Kaolin is found to have a greater effect on the mechanical properties, water absorption, and thermal conductivity of the mortars than Flint. This behavior is discussed and analyzed based on the compositional and structural properties of the rocks powders.

Pull Out

The quantity of polymer waste in our communities is increasing significantly. It is therefore necessary to consider reuse or recycling waste to avoid an increase in the risk to public health. This project is aimed at using pulverized low-density polyethylene (LDPE) waste as a source to reinforce and improve compressive strength, and to reduce the water absorption of geopolymer ceramics (GC). Clay:LDPE composition consisting of 5%, 10%, and 15% LDPE was geopolymerized with an NaOH/Na2SiO3 solution and cured at 30 °C and 50 °C. Characterization of the geopolymer samples was carried out using XRF and XRD. The microstructure was analyzed by SEM and chemical bonding by FTIR. The SEM micrographs showed LDPE particle pull-out on the geopolymer ceramics’ fracture surface. The result showed that the compressive strength increases with the addition of pulverized polymer waste compared to the controlled without LDPE addition. Water absorption decreased with an increase in LDPE addition in the geopolymer ceramics composite.
