Amino Sulfuric Acid Superplasticizer Supplier AS ASTM C **4, Type F Aminosulfonic Acid-based Superplasticizer Description Amino-Arylsulphonate Phenol Formaldehyde Condensateï&frac*4;ˆASï&frac*4;‰is a high range of water reducer, commonly referred to as a superplasticizer. It is an aqueous solution of a modified amino sulfonate and organic compounds. It contains no added chloride and meets the requirements of chemical admixture specifications for concrete: ASTM C **4, Type F, GB********7, GB*********3. Uses 1.AS has the advantages of no air-introducing, low addition rate, low slump loss, and decreasing viscosity. At normal condition, it can be prepared for flowable concrete of C**-C*0 without using strength enhancing agent. 2.Applicable in any silicate concrete. It has almost the same effect on the setting time for different cement. No abnormal setting would appear. 3.Applicable in concrete precasting and steam-curing for both industrial and civil construction project. 4.Applicable for commercial concrete. Available for base material for compound admixtures, flowable and self-compacting concrete, ***** can be mixed with Naphthalene-based superplasticizer which can achieve better water reducing rate and high strength performance. 6.AS is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation. Advantages 1.Low addition rate: For solid product, the addition rate is 0.**0.6%. Over addition will cause cement particles dispersed, which will reduce water reservation and increase bleeding and segregation. 2. Low slump loss: It can satisfy the requirement of long time and distance transportation. It is ideal for commercial and pumping concrete. ***** durability. It has the property of high volume stability, anti-seepage and anti-freezing. 4.Wide applicability. It can be used with different variety of cement.
