Paper Title:
Study of Applied Properties of Aminosulphonic Acid Based Superplasticizer
  Abstract

The adaptability to cement pastes and fresh concretes of aminosulphonic acid-based superplasticizer (ASP) and its water reducing ratio and compatibility with Naphthalene based superplasticize (FDN) have been investigated at a given content of ASP. The adaptability to cement pastes was determined by measuring the fluiditiy with time of superplasticized cement pastes, and the adaptability to fresh concretes and compatibility with FDN was evaluated by measuring the fluidity, bleeding, and hardening and mechanical property et.al. of fresh concretes with ASP. The results show that the fluidities at 120 min of cement pastes, with 1.6% of ASP, are over 140 mm, and it increases with the increase of ASP. There is a positive relationship between the water reducing ratios of ASP and its content, and the highest of the water reducing ratio(the highest value is 28%). Moreover, the simultaneous addition of ASP and FDN can effectively decrease the bleeding of concrete.
