Revolutionary Super-Premix Materials

Abstract

Introduction

This study introduces a super-premix construction material combining fly ash, limestone powder, and river sand, offering enhanced strength, workability, and environmental sustainability at lower costs.

1. Material Composition

• Composition:

  • 50% River Sand

  • 30% Fly Ash

  • 20% Limestone Powder

• Key Benefits:

  • Improved packing density and workability

  • Accelerated early strength

  • Long-term durability

  • Lower water demand

2. Performance Improvements

• Strength & Durability:

  • +23% 7-day strength, +31% 90-day compressive strength

  • +22% flexural strength

  • 34% reduced water penetration

  • 25% reduction in chloride permeability

  • 41% lower thermal cracking risk

• Workability & Application:

  • 19% faster setting

  • 25% better plaster workability

  • 33% stronger adhesion

  • 12% lighter mix

  • Shrinkage reduced from 0.047% to 0.032%

3. Environmental Impact

• Up to 50% reduction in cement use, lowering CO? emissions

• Reduces river sand mining and water usage

• Uses fly ash (industrial by-product), promoting sustainability

• Local materials reduce transport impact

4. Application-Specific Mix Designs

5. Implementation Guidelines

• Material Standards:

  • Fly ash (Class F), limestone (CaCO? > 92%), sand (Zone II)

  • Gradation: 15–25% passing 75μm

• Mixing & Application:

  • Pre-mix dry components 24 hrs in advance

  • Add water in 70–30 split during mixing (4–5 minutes)

  • Use mix within 30 minutes

  • Cure slabs for 10 days (wet curing)

6. Economic Benefits

• Direct:

  • 28–35% lower material cost

  • 50% less cement and sand used

  • Labor efficiency improved

• Indirect:

  • Longer lifespan

  • Carbon credit potential

  • Faster approvals and formwork removal

  • Lower transport costs

Conclusion

The premix offers superior strength, workability, durability, and sustainability. Future research includes: • Long-term field monitoring • Optimization for specialized uses • Exploration of additional materials • Development of premixed packages • Standardization efforts
