Formula for precast concrete products
Suplast® SPT-A80D is a high range water-reducing admixture . Its unique formulation is based on the polycarboxylate technology. SPT-A80D meets the requirements of GB8076-2008, standard of the P. R. of China.
SPT-A80D is recommended for high strength precast concrete products,
retention, and increased early/ ultimate strengths are required. SPT-A80D
can be used for production of High
Performance Concrete (HPC) of high flow and low ratio of water to cementitious
materials, as well as for production of conventional slump concrete.
The fluidity of cement paste dosed with SPT-A80D shows the performance as follows.
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 even at an extreme low water/cementitious
materials ratio. The
dispersing action maximizes cement hydration efficiency and obviously
increases early and long term compressive strengths of the concrete .
At a lower dosage, SPT-A80D can be used as a cost effective mid
range water reducing admixture (about 20% water reduction) for
production of conventional slump
concrete. SPT-A80D will improve
workability and finishability.
.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%.|
Specific gravity: approx.1.16-1.20
|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-A80D is a concentrated product with 50% of solid for lower-cost delivery. It can be directly used for concrete mixing, but usually diluted with water before use. The appropriate concentration of application is about 20%.
Technical supports for applications are always prompt, effect and satisfied from our experienced engineers.
