Efficient and environmentally friendly expanders

 Efficient and environmentally friendly expanders for high performance concrete cracking and seepage, cancel waterproof, and extend the telescopic spacing, or seamless construction operations. Long reinforced concrete structure, in order to prevent the concrete cracks due to shrinkage and temperature difference should be set joints, cast reinforced concrete structure according to the relevant provisions of the specification, joints no more than 30 meters in indoor, outdoor no more than 20 meters, after four -6 days to caulk. As the construction of complex, long duration, so the construction units are hoping to extend or cancel after pouring seam, join expansive joints extended distance. Joint Distance control more appropriate within 80 meters. Efficient and environmentally friendly expanders Application: 1, to achieve structural waterproof: Cancel outer waterproof measures to improve the economic efficiency 2/3; 2, after the abolition of the long cast Cast Zones: underground engineering 60M long after pouring with no more than 60M to strengthen the expansion after pouring belt belt replace, reduce costs and shorten the construction period; 3, mass concrete temperature cracks control: product, relax temperature indicators, generally do not have to use cooling aggregate, cooling pipes embedded in concrete and other traditional construction method, saving construction costs; 4, roofing cast construction: the MPC cast roofing and other products, has a simple structure, low cost, waterproof durability and other characteristics, has been widely used.
