INVESTIGATION OF THE INFLUENCE OF APPLICATION OF BIOPLAST-1 PLASTICIZER ON FROST RESISTANCE OF CONCRETE

Abstract

Monolithic construction is developing, and every day concrete acquires more and more specific characteristics: faster or slower, depending on the need, they gain strength; become resistant to low temperatures; become waterproof; different colors and shades; protect steel structure elements from corrosion; gain resistance to aggressive environments and durability, without losing their physical properties. The key to everything is a complex chemical additive, which is added to concrete during its production or to the finished concrete mixture. The use of the additive will significantly increase the profitability of concrete mixtures, because the introduction of a complex chemical additive developed jointly with the Navikon-Ukraine company will improve the physical characteristics of concrete, significantly reduce the cost and increase the quality by an order of magnitude .

NavyCon KMD  is a complex of mineral chemical modifiers for improving the hydrotechnical and physico-mechanical properties of concrete and construction solutions used in civil and industrial construction, tunnel construction, for the repair and restoration of bridges and overpasses, road construction, in particular in the manufacture paving slabs with increased strength, waterproofing and frost resistance, to obtain a concrete mixture of high plasticity and homogeneity; increased strength of concrete and concrete products; increases their waterproofness, frost resistance, gas permeability and resistance to abrasion and sulfate corrosion in conditions of high humidity and significant temperature changes. It can be used for the production of dense artificial products in the form of pipes, segments, blocks, tiles and other products used in conditions where increased waterproofness and frost resistance are required. The use of Navikon KMD in the composition of concrete, cement-sand mixtures increases their waterproofing capacity by three to four degrees, allows to exclude additional waterproofing of structures, gives them increased strength, frost resistance and resistance to the influence of aggressive environments.

The effect of the complex modified additive Navikon KMD on the mobility of the concrete mixture and the strength of concretes, which are widely used for the production of precast reinforced concrete structures, is investigated in the work. It was established that the use of the additive leads to an increase in the grade of ease of placement of the concrete mixture by three degrees, from P1 to P4 (OK from 1-4 cm to 16-20 cm) relative to the control mixture.
