Annotation: The effect of the waterproofing admixture «Penetron Admix» on the properties of heavy concrete under normal curing conditions was studied. The expediency of using this chemical admixture at the stage of preparing a concrete mixture has been established. Studies have shown that with the introduction of an admixture in an amount of 1 %, there is an increase in strength by 3,7 % compared to reference concrete without an admixture. A further increase in the amount of added admixture to 1,5 % has virtually no effect on the concrete compressive strength. Also, the introduction of the «Penetron Admix» admixture increases the water resistance of concrete from W4 to W8. In this case, the filtration coefficient decreases from 5,4·10-9 to 7,8·10-11 cm/s. This is due to the fact that with the introduction of the «Penetron Admix» admixture, conditions are created for the crystallization of hydrated calcium silicatein the form of acicular crystals that fill the cavities between the grains. In addition, the pores and capillaries are filled due to the loosening of the tobermorite gel. Which is to say that the admixture actively includes the process of formation of new crystals that fill the cavities between the concrete particles.
Keywords: heavy concrete, «Penetron Admix» admixture, water resistance, strength, concrete structure.
