BASIC PROPERTIES OF CONCRETE WITH ADDITIVE D - 5
• HIGH WATER RESISTANCE: Concretes with D - 5 acquire the maximum possible water resistance (up to W20 and more), which allows to completely exclude any additional waterproofing of concrete located in water - saturated soils in an aquatic environment or directly in water. High water resistance of concrete with D - 5 additive is preserved for the entire service life of the structure. In rooms with high humidity, plastered with the additive D - 5, dampness and "fungus" disappear.
• HIGH SULPHATE RESISTANCE: Concretes with D - 5 additive acquire high sulfate resistance even when using ordinary Portland cement. This makes it possible to exclude additional waterproofing of concrete during its operation in an aggressive environment, including sea water, oil and oil products.
• HIGH STRENGTH: The use of additive D - 5 increases the strength of concretes at the age of 28 days by 30% - 70% in comparison with concrete without additives (in equally mobile mixtures), or allows to reduce cement consumption by 15 - 20% .
• ACCELERATION OF THE STRENGTH GAINING PROCESS: Standardized 100% - the strength of concretes with the addition of D - 5 is achieved within 3 - 7 days of hardening under normal conditions, which allows reducing the time of monolithic construction by at least 25 - 30% while improving quality and durability structures; and in the production of prefabricated reinforced concrete structures, it eliminates the process of heat and moisture treatment, replacing it with heating in a "thermos" at a temperature of 30 - 40 ° C.
• HIGH FROST RESISTANCE: The use of additive D - 5 increases the frost resistance of concretes by at least 2 grades and makes it possible to obtain concretes with frost resistance F400 and higher.
• PLASTIFYING: Additive D - 5 increases the mobility of concrete mixes from P1 to P5, or reduces water consumption by 15 - 20% in equally mobile mixes. When using additive D - 5, there is no need for additional use of plasticizers.
• STABILIZING: Additive D - 5 gives the concrete mix water retention ability, prevents delamination and improves pumpability. Increases the preservation of the mobility of concrete mixtures up to 2 hours or more (with an initial mobility of OK = 22 - 23 cm).
• AIR INTRACTION: Additive D - 5 provides a standardized air entrainment in the concrete mixture within 3 - 4% for non - additive cements, and 4 - 6% - for cements with slag content up to 15% .
• SELF - HEALING OF THROUGH CRACKS up to 0.8 mm wide, which may appear in structures during operation due to dynamic loads, including seismic ones. Prerequisite: water filtration through cracks. Under normal conditions, this property is manifested in the fact that "cold" joints in concretes with D - 5 additive do not leak even during long breaks in concreting.
• ECOLOGICAL: Additive D - 5 does not contain in its composition components dangerous for cement stone and reinforcement, it does not form toxic compounds in the air and in water. Additive D - 5 is approved for the production of concrete and reinforced concrete structures in contact with drinking water.
Recommended dosage: 2 - 3% by weight of cement

FIELDS OF APPLICATION OF ADDITIVE D - 5
Additive D - 5 has proven itself well in the construction of concrete and reinforced concrete structures in contact with water. It is used in the construction of foundations, tunnels, bridges, piles, underground parts of buildings, hydraulic engineering facilities, reservoirs, piers, river and sea ports. In this case, no additional waterproofing is applied.
Additive D - 5 is used in the construction of critical structures - high - rise multi - storey buildings, television towers, chimneys, cooling towers, power transmission towers, granaries, airfield runways, load - bearing structures made of pre - stressed reinforced concrete, etc.
It is recommended to use the additive D - 5 when performing plastering works on the facades of buildings and structures (including by gunning); when carrying out repairs in rooms with high humidity and in order to eliminate "fungus"; in the manufacture of concrete and mortar screeds (including under "warm floors"); in the production of dry building mixtures and small - piece concrete products. D - 5 is effective in the manufacture of cement slurries, cementation of concrete space in tunnels and mines, in the manufacture of filling mixtures for filling mine workings.
Advantages of using the multifunctional additive D - 5
- The construction technology is being simplified.
- The construction time is significantly reduced (by 25 - 30% ).
- The finished structure acquires high performance characteristics.
- Effective cost savings are achieved (secondary waterproofing treatment of concrete surfaces is not required, cement consumption is reduced, operating costs for the maintenance of buildings and structures are significantly reduced, etc. ).
