| >>products | ¡¡ | ¡¡ Suplast® SPT-B60 High Range Water-Reducing Admixture Suplast® SPT-B60 is a high range water-reducing admixture . Its unique formulation is based on the polycarboxylate technology. SPT-B60 meets the requirements of GB8076-2008, standard of the P. R. of China. |
|
| Applications |
SPT-B60 is recommended for high strength precast concrete products and
ready-mixed concrete, whenever high plasticity, prolonged slump
retention, and increased early/ ultimate strengths are required. SPT-B60
can be used for production of Self Consolidating Concrete (SCC) £¬High
Performance Concrete (HPC) of high flow and low ratio of water to cementitious
materials, as well as for production of conventional slump concrete. ¡¡ |
||
| Performance |
The fluidity of cement paste dosed with SPT-B60 shows the performance as follows.

||
| Benefits |
When used as a high range water reducing admixture, water reduction up
to 35% can be obtained. The superplasticizing action allows for the
production of high slump flowing concrete with excellent workability and
prolonged slump retention that can be placed with less vibration even at a
very low water/cementtitious materials ratio. The dispersing action
improves cement hydration efficiency and increases early and long term
compressive strengths of the concrete . Prolonged
slump retention does not have negative effect on set times. At a lower dosage, SPT-B60 can be used as a cost effective mid range water reducing admixture (about 20% water reduction) for production of conventional slump concrete and ready-mixed concrete. This application is ideal for use with lean, harsh concrete mixes or concrete containing flyash. SPT-B60 will improve workability and finishability. The combined water reducing and superplasticizing action provide the following benefits: .Prolonged slump retention will extend workability and make pumping-transfer easily. .Increased slump improves workability and reduces labor costs. .Much higher early and ultimate strengths
for cost effective high strength concrete and .Accelerated early strengths allow faster demolding and more efficient use of forms to |

| Dosage | For concrete with compressive strength of 30Mpa-50Mpa, the dosage is 0.12%-0.18%(in solid) of the weight of cementitious materials. For concrete with strength more than 50Mpa, the dosage is 0.20%-0.30%. Some retarders (such as Sodium Gluconate) may be added for ready-mixed concrete to prolong the setting times. | ||
| Specification |
Concentration: 40%, 50% Specific gravity: approx.1.16-1.20 |
||
| Appearance | Yellowish liquid | ||
| Package | 30kg,250kg barrels and 1000kg tanks are available for export. | ||
| Shelf life | When stored in dry and cool warehouses, the shelf life is 24 months. | ||
|
SPT-B60 is a concentrated product with 50% of solid for lower-cost delivery. It is not directly used for concrete mixing. SPT-B60 is usually diluted with water and/or combined with some retarders (sodium gluconate etc.) in order to prolong the set times for long-distance transport or some special purposes. The appropriate concentration of application is about 20%. Technical supports for applications are always prompt, effect and satisfied from our experienced engineers. |
