Influence of upper micksels of soil on density dryboard concrete

Abstract

The effect of acrylic latex micelles of hydrophobic colloidal surfactants on the strength of fine-grained concrete has been investigated in this work. At this time, a steady trend has been the application of various types of catalysis to almost all reactions that are used in chemical technology. It should be noted that the use of catalytic methods to improve the effectiveness of chemical reactions has a special peculiarity. Such transformations are complex systems within the network of subreaccounts, so traditional methods of accelerating chemical processes, in particular the use of high temperatures, acids or bases, often do not give the desired result. Micelles of hydrophobic surfactants have an interesting and very valuable property: they can bind different molecules and ions. The micelles provide transportation of insoluble specimens due to unfavorable in other cases the phase of the solution. For example, using micelle transport substances can be used to accelerate maturation and growth of crystals. The purpose of this work is, for example, the use of acrylic latex to demonstrate the possibility of using a micelle filled organic substance of hydrophobic surfactants of an aliphatic type as a means of controlling the strength of fine-grained concrete. To achieve this goal, the task was to investigate the change in the strength of fine-grained concrete from the contents of a micelle filled with acrylic latex. As a result of the performed experiments, it was established that the introduction of acrylic latex into the concrete structure leads to a significant increase in the strength of concrete under compression. It is proved to increase the strength of the specified concrete and its dependence on the water-cement ratio and the amount of micelles filled with acrylic latex of hydrophobic colloidal surfactants. The optimum amount of acrylic latex in concrete, which provides the maximum increase in its compressive strength, depends on the water-cement ratio in it and decreases with an increase in the water-cement ratio. The value of the relative strength of concrete in compression when introduced into its composition, the acrylic latex ash increases with decreasing the water-cement ratio.
