water-reducing agent การใช้

• Synthesis of water - reducing agent of polycarboxylic acid concrete
• The application of polysodium acrylate in as ceramic water - reducing agent
• The adsorption conformation of water - reducing agents for gypsum and its dispersion stability
• Application of scour and abrasion resisting high grade concrete mixed with silica powder and retarded water - reducing agent in zipingpu hydropower station
• By measuring the temperature of the cement paste with the water - reducing agent , we discover that the water - reducing agent can retard the cement hydration
• Under the conditions of high efficiency water - reducing agent , the homogenization of starch mixed composite powder is better than that of blank cement and only mixed fly ash
• The new type of high effective water - reducing agent we developed based on naphthalin series has characteristic of retardarce . it can reduce slump loss through its slow solution
• Polycarboxylate series high range water - reducing agents , which can provide concrete high fluidity , good retarding performance and low slump loss , have become more popular recently
• And the relationship between these factors and molecular weight has been concluded . the best process of maleic anhydride - co - acrylamine copolymer as the water - reducing agent has been designed
• Development of poly - acrylic series water - reducing agent ( wra ) was a modern frontier research project . the poly - acrylic wra was characteristic of lower additive , higher fluidiffication effect , and preventing concrete mix from slump - loss with time duration
• In order to improve the performance of the maleic anhydride - co - acrylamine copolymer water - reducing agent , the copolymer is monoesterified with the polyethylene glycols . the fluidity of the esterified copolymer has been increased 60 % , and it has good retarding performance
• Water - reducing agent , which researched by china building material science research institute . the company has established annually 30000 tons and 40000tons production lines and invited many experts and professors as technical adviser in colleges and science research institute
• Such methods as compounding retardants , compounding water - reducing agents ( which has various the extent of condensation ) , changing the ways of addition and retardarce method , are used to impolder new water - reducing agent and construction method to salve slump loss , but it can not work drastically
• The new high effective water - reducing agent act - fdn has characteristic of reactivity , it ca n ' t dissolve in water but do in alklia . in the concrete , it decompounds slowly and gives out sulfonate group which has dispersity , this can make the high effective water - reducing agent available for a long time , therefore it can reduce slump loss
• We have successfully developed , researched and produced concrete expansion agent , high performance water - reducing agent , pump - sending agent , quick - coagulating water - reducing agent , high performance concrete mixing material , green environmental senior inner wall putty , pcc spring concrete waterproof coating and so on . our series products have gained high fame among our clients after being put into market
• The best process of sulfomethylated poly ( maleic anhydride - co - acrylamide ) is also designed . by testing setting time and water reducing rate of water - reducing agent , we find that the water - reducing ratio of the monoesterified ma - am is 20 % , and the sulfomethylated ma - am is 6 . 3 % . they both have good retarding performance
