Improvement of Physicomechanical Properties of Cement Mortal And Cement Stone at Fastening Bottom Zone
R.A. AhmedovIn article influence of concentration of structure nanoparticles on physicomechanical indicators water - cement and acid cement mortal is investigated. First of all investigations defined the density, spread limit of mixture of water and chloride calcium with, the beginning and the end of the period of solution seize, durability against bending and compression, and also permeability of a cement stone. For the purpose of studying of influence of concentration of a nanoparticles on the above stated physicomechanical properties of a cement mortal and a stone, 3 different models with the additive clay extracted with local deposits and nanosizes a metal have been made. It is defined that the increase in concentration of liquid in hydrochloric acid cement reduces durability of cement stone against bending and compression. Researches in layer model have been investigated for the purpose of studying of influence of environment on the durability, the period of solution seize swing in the bottom of the well, and also permeability of a cement stone. It is revealed that the condition of the layer influences the zone of the bottom. In all cases adding 0,05 0, 1 % nanocontent solution, durability and permeability of a cement stone increase by 15 20 % and the best result is got with adding nanocontent in mixture at first.
