Self-consolidating Concrete (SCC) is widely used in pre-cast products such as stairs, walls, pillars, and architectural forms for prefabricated structures such as parking garages, tunnels, tanks and basins, and for ready-mix concrete applications such as pouring floors and pumped concrete.
Engineered Limestone is a cost-effective, high-performance additive designed to improve the quality and processing of concrete.
Put PREMIACAL in your self-consolidating concrete (SCC) mix for optimal performance, improved appearance and increased cost savings.
SCC is a highly flowable, non-segregating concrete that can spread into place, fill the formwork and encapsulate the reinforcement without any mechanical consolidation. In general, SCC is concrete made with conventional concrete materials and the addition of specialized chemicals called superplasticizers. In order to achieve the high flow rates of SCC, fine particles are needed. PREMIACAL is the fine particle.
The fines in PREMIACAL improve the cement particle-size distribution and achieve a better packing density. The fine fraction of PREMIACAL increases the specific surface area of cement, while its coarse fraction bridges the gap between the sand and Portland cement (Figure 1). The replacement of a portion of cement with PREMIACAL will improve filling ability (flowability) and stability without affecting the early strength.
- Engineered Limestone is a manufactured fine particle that fills in space in the concrete matrix
- Added separate from the cement
- Savings through cementitious content reduction
- Increased workability
- Catalyzes the hydration of cement…Good early (green) strength with lower cement contents
- Initial and final set are not effected by
- Reduced bleeding
- Increased mortar viscosity with less segregation
- Better flowability resulting in improved finishes
- Consistent particle size distribution and color
- Reduces costs without sacrificing performance
- Reduces greenhouse gases by lowering cement requirement
- Keeps concrete producer in control of his mix design
