The aim of the study is to identify patterns of influence of mineral and vegetable oils with different viscosities on the deformation properties of concrete and cement-sand mortar. An experimental study of the change in the samples’ deformation under static axial compression has been performed. It has been established that the influence of mineral and vegetable oil on the deformative properties of concrete and cement-sand mortar depends on the oil’s viscosity. Empirical mathematical models have been worked out to predict the variation of longitudinal and transverse deformations of concrete under static axial compression.
This article contains data of longitudinal and transverse deformations of concrete and cement-sand prisms impregnated with mineral I-30A, corn and olive oil, under axial compression up to loads that do not create destructive stresses. The stress level, as the ratio of the compressive stress σ to the design compressive strength Rb, varied from 0.054 σ/Rb to 0.845 σ/Rb. The values of deformation for various axial compression loads are presented for control samples and for samples impregnated with mineral oil I-30A with a viscosity of 15 °E, corn oil with a viscosity of 9 °E, and olive oil with a viscosity of 11 °E on Engler scale. The data are associated with the research article “Influence of viscosity of vegetable and mineral oil on deformation properties of concrete and cement-sand mortar”.
Self-compacting concrete was obtained by partially replacing Portland cement with a previously prepared rice husk ash Preliminary preparation included the thermal treatment of the ash under various conditions. The optimum technology of preparation, allowing to receive a homogeneous concrete mix is revealed. All concrete mixtures were designed in such a way as to have a slump flow of 680 ± 30 mm in diameter, which was achieved by using different dosages of a superplasticizer based on polycarboxylate ether. All mixtures with the replacement of cement by ash to 25 % meet the requirements for rheological characteristics and resistance to segregation. The bulk density for the samples with 10 %, 15 %, 20 % and 25 % of the rice husk ash was reduced by 3.19 %, 5.18 %, 5.58 and 6.37 % respectively, compared to the samples without ash. An increase in the rice husk ash content led to a decrease in the early mechanical properties, while the final strength of self-compacting concrete containing ash was comparable to conventional samples. This was achieved due to the pozzolanic activity of the ash. Inclusion of rice husk ash reduced the amount of portlandite in the system by obtaining an additional C-S-H gel, which led to matrix compacting and blocking of networks with open porosity.
Soil-concrete is widely used to strengthen the foundation footings, in the construction of roads and railways, as well as for the production of bricks and pavement tiles. One of the most important physical and mechanical properties of soil-concrete is the compressive strength. We carried out a study of soil-concrete strength depending on its curing conditions and percentage of cement. For our study we used loam soil with the plasticity index of Ip = 12.3, Portland cement of type I, ground limestone with the specific surface of 4500 cm2/g, polycarboxylate based superplasticizer and water for mixing. Curing of samples was carried out in air-humid condition in wet sawdust and also with the thermal-humid treatment in a steam chamber. It is experimentally established that the strength of soil-concrete depends not only on the ratio of clay aggregate and mineral binder, but also on the temperature and humidity conditions of curing. Additives of ground limestone and superplasticizer contribute to increase the compressive strength of soil-concrete. A mathematical model for determining the compressive strength of soil-concrete depending on the percentage of cement and the curing period is developed. This proposed mathematical model is advisable to apply for assessment of the compressive strength of soil-cement massive layer after the urgent repair of under-road pipelines.
One of the important tasks when designing the water fittings is to calculate the orifice area of locking pair for passing the calculated water flow at a calculated pressure. The method of determining the orifice area with smoothly changing shape based on the piecewise-element method is proposed. This method is characterized by a comparative simplicity and sufficient accuracy for engineering calculations to determine the orifice area of the disk type locking pairs for the valve head. The proposed method allows us to determine the required size of the orifice area for passing the calculated water flow and also to determine the water flow rate depending on the opening level of orifice. The authors carried out the necessary calculations and manufactured ceramic disk type locking pairs by using the proposed method. Bench tests of water fittings with valve heads those are having orifices with smoothly changing shapes (in the form of bent blob) showed that water flow is changing almost in proportional to the tap opening. This method can be used not only for the designing of the water fittings and also for the shut-off valves of various purposes.
