Abstract

Using the method of dynamic light scattering we investigated the influence of the rotor and pulse impact on a dimensional change of particles in calcium chloride hydrosol used as texturing additives in concrete mixing. The mechanism of the strengthening action of the additive is shown by the results of an assessment of the parameters of the pore structure of the cement stone which is carried out by the method of the low-temperature adsorption and desorption of nitrogen vapors. With the use of the method of the low-temperature adsorption desorption of nitrogen for the analysis of porosity of the experimental exemplars of the cement stone received with the use of the mechanically activated CaCl2 solution, decrease in the area of a specific surface area in 1.7 … 2.1 times and the volume of pore spaces by 1.6 times that is caused by preferred decrease of the maintenance with the diameter over 6 nanometers and decrease in an upper bound of pore size from 160 to 90 nanometers is shown.
