Introduction
SPC-01(water reducing type) is an Eco-friendly high performance polycarboxylate-based superplasticizer developed by our company with DD-906(HPEG2400) as main raw material. SPC-01can greatly enhance the strength and durability of the concrete.

Characteristics
1. High water reducing ratio: Excellent dispersity and water reducing ratio can reach 36% or above at saturated addition amount 

2. Good slump retention: It can well delay the transportation and on-site retention time of the concrete, assures the pumpable performance of the concrete.

3.High strength growth rate:It has higher early strength growth rate, can improve shrinkage performance and reduce the carbonation rate of concrete.

4.Good adaptability: It has good dispersity and flowing retention ability to variety of silicate cements, common silicate cements, slag silicate cements and various admixtures. 

5. Environment friendly: No formaldehyde and other harmful ingredients.

6. Low energy consumption and low cost:Short reaction cycle,low energy consumption, and low cost. It is quite adaptable to commercial concrete mixing station.

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.
