Self-Consolidating Grout
Need:
In self-consolidating grout, the grout is more liquid and flows into the smallest of voids, thus eliminating the need for the grouting process. The pressure head from the column of grout helps to push the grout into voids. There are chemicals that can be added to traditional grout mixes to make self-consolidation, however, the chemicals are expensive and change the characteristics of the grout that make placement more difficult (requires an experienced and skilled mason to use). The additional expense and the level of expertise often negate the benefits.
Solution:
Researchers at Cal Poly have created a self-consolidating grout mixture free of polymeric admixtures. The cost effective mixture relies only heavily on the replacement of cement with fly ash and ground granulated blast slag (GGBS), which are waste products. Thus the solution to the challenge becomes a GREEN and SUSTAINABLE solution, for the high embodied energy material (cement) is replaced with highly available waste products.
Applications:
- Tiling
- Concrete Masonry Units
Advantages:
- Better flow characteristics
- Reduced void formation
- Do not require vibration to flow into passages
- No polymeric admixtures
- Cost reduction
- Energy savings
- Sustainability improvement
