SPC-100 Polycarboxylate-based superplasticizer
Product introduction
SPC-100 (economical type) is a environmental superplasticizer. It is a concertrated product. High water reduction, high slump retention ability, low alkali content for the product. It can be widely used in premix of common concrete, gushing concrete, hydro concrete. Especially! It can be used in high strength and durability concrete have excellent capability.
Principle of function
Molecular main chain of polycarboxylate high performance water reducer is firmly adsorbed on surface of cement granule where can efficiently counteract hydration reaction and increase its plasticity.Branched chain surround cement granule having sterically hindered and electrostatic exclusion function which is different from conventional imparts excellent dispersing ability and effect of water reducing which make integrative characteristics of concrete improve greatly.
Production Characteristic
1、High water reduction:The water reduction rate of concrete is above 38%
2、High slump retention ability:delay time of transporting concrete and time of detention at construction site
3、excellent workability.high fluidity,easily deposing and compacting.make concrete reducing viscosity,without bleeding and segregation, easily pumping.
4、Wide adaptability:It is compatible with ordinary silicate cement, silicate cement, slag silicate cement and all kinds of blendings having excellent dispersibility and plasticity
5、Excellent durability: low lacunarate,Low alkali and chlorin-ion content. Enhancing concrete strength and durability
6、Environmental friendly products: No pollution during production
Methods of use
1、The recommeded range of dosage of SPC-100 is suggested as follows(wt.% of cement):0.5%-1.6%.
2、It can be mixed in metric water or added in concrete mixer.The recommended stirring time is 150s at least.Concrete mixing test should be made before using in order to insure concrete quality.  3、It can be compounded together retarder, defoamer, air-entertraing reagent,lignin sulfonic natrium and so on.
4、SPC-100 product is sold as concontrated. It is not suggested to use SPC-100 products directly in concrete or other materials without formulation blending. The compatibility of SPC-100 products to particular cement, aggregate and the other raw materials in the application is not guaranteed. It should be obtained through trial mixes and formulation technologies by the users.
Scope of Application
1、SPC-100(20%) is a superplasticizer used in premix of construction and cast-in-place concrete.
2、It is especially suitable high strength concrete for railway, haven, traffic, bridge and electric power and so on.
3、 It is suitable for the preparation of high strength, high durability, self-compacting, steel fiber and self-leveling concrete.
