Mixtures based on sulfoalyuminatnyh cements

One of the urgent problems faced in building a defense constructions and buildings against water penetration. It is known that water not only flowing through constructive and cracks, it destroys the structure of construction materials, reducing the term of one of the acute problems faced in building a defense constructions and buildings against water penetration. It is known that water not only flowing through constructive and cracks, it destroys the structure of construction materials, reducing the lifetime of objects. Obmazochnaya waterproofing cement-concrete structures are widely practiced today as at work and at home. There are book a "tube" (quick-growing) and penetrating materials based on Portland cement with additions of volcanic or sedimentary rocks and set an artificially derived salts. With the participation of leading research institutes in Russia have been created materials "Strimsmes" and "Strimplag" based on sulfoalyuminatnyh cement for waterproofing. Their uniqueness lies in the use of specific heats sulfoalyuminatnogo clinker, used in production of high-alumina cement. "Strimsmes" - is a penetrating waterproofing and book activities. "Strimplag - superbystrotverdeyuschy sealant for coining seams, joints, stop active leaks. The advantages of mixtures based on sulfoalyuminatnogo clinker: high strength under all conditions of hardening, setting fastest time - the beginning of 30 seconds (superbystrotverdeyuschie), 15-20 minutes (fast setting); frost - at least 350 cycles, high resistance against the corrosive action of aggressive solutions (5 % solution of sodium sulfate - coefficient of 0.96, 1% solution of magnesium sulfate - coefficient of 0.87; sea water - the coefficient of 0.92). Mixture of different resistance to high temperatures, which is their unquestionable advantage over the vast majority of waterproofing materials on the basis of conventional portland cement. For non-shrink repair mortar designed quick-dry concrete mix "REMSTROY with polymer fibrils with thick filling of 10 mm and above, have reduced heat of hydration. They are characterized by high turnover and nerasslaivaemostyu with good adhesion to metal and concrete. Materials characterized by high frost resistance, fast curing (up to 1 day compressive strength - 20 MPa for 28 days - 50 MPa). To restore the vertical and inclined surfaces form a thixotropic mixture. Materials into technology and easy to use as a mechanized or manual way. >
