Betono stiprinimo kristalizacijos būdu tyrimai / ; Investigations of concrete strengthening using crystallisation method.
Reinforced concrete hydraulic structures are constantly exposed to external and internal impacts. With the lapse of time these structures deteriorate. Therefore, they must be repaired and strengthened. This paper considers way to strengthen concrete structures using “Xypex” material. Studies were carried out to obtain the compressive strength, water absorption, density and water tightness. Results showed that concrete, impregnated with “Xypex” material, becomes stronger and more impermeable to water, which makes structures more resistant and durable. The stronger and more impermeable concrete is, the more frost resistant it is, and this is the main indicator of durability of hydraulic structures. After the compression test was determined the impregnation of concrete with mineral material „Xypex“ its strength to grew. The maximum compressive strength of the exchange effect is reached within the first month where the strength increased by an average of 57 %. After the water absorption tests we can assertion about „Xypex“ material in concrete reduces the water absorption. This rate dropped the most in the first month on average about 10 % and the other five months, the water absorption decreased 8 %. After density studies set the impregnation of concrete with mineral material „Xypex“ the density increased. Intense density exchange is seen after one month where impregnated concrete, density increased to 1,8 %. After the depth of penetration of water under pressure in hardened concrete tests, we can assertion about „Xypex“ material, it reduce the concrete the depth of penetration of water. This index dropped after six months - on average 42 %. After the frost-resistance tests set that the impregnation of concrete with mineral material „Xypex“ its resistance to cold increased. The biggest change is the effect achieved during the first month where resistance to cold increased by an average of 37,2 %.
