Introduction

SPS-03 (slump retention type) is a new generation of Eco-friendly high performance polycarboxylate superplasticizer 
developed by our company with DD-909 (TPEG2400) as main raw material, SPS-03 can improve the plasticity of the fresh concrete owing to its superior slump retention property, extremely high water reducing ratio, thus greatly enhance the pumping and workability of the concrete. 

Advantages/Characteristics
1. High water reduction
2. Low dosage
3. To maintain slump perfectly
4. To enable a much better flowability of the mixture
5. To improve the strength and durability of the concrete drastically
6. To save cement at equal strength and durability
7. Eco-friendly since no formaldehyde or benzene

Usage
1. Generally, the dosage range is 0.25%-0.8%, it can be beyond this range properly for special cements or aggregates.

2.The recommended stirring time is at least 150s for good water reducing effect.

3.It can be compounded with various retarders and sodium lignosulphonates.

Application Scope
1. It is applicable to ready-mix concrete and precast concrete for industrial and civil architectures, especially to low grade commodity concretes.
 

2. It is particularly applicable to various national construction works with high performance requirements for the concrete , such as water industry, marine works, seaports, traffic, electric power etc.

3. It is applicable to the special concretes, such as high strength, high durability, self-compacting concrete and various prefabricated parts etc.
