👉RECYCLABLE AND LOW-CARBON CONCRETE

💫Recyclable and low-carbon concrete refers to concrete mixtures and construction practices designed to reduce environmental impact while maintaining performance. Here's a breakdown:

♻️ Recyclable Concrete
Concrete that can be reused or recycled at the end of its life.

🏷Key Features:

⏺Recycled Aggregates: Crushed concrete used in new mixes.
⏺Supplementary Cementitious Materials (SCMs): Like fly ash or slag, reducing cement use.
Concrete Reuse: Whole blocks or panels reused in modular construction.
⏺Demolition-Friendly Design: Enables easy separation of materials.

🌍 Low-Carbon Concrete
Concrete with reduced greenhouse gas emissions, especially CO₂.

⏺Low-Carbon Strategies:
Cement Replacement:
Fly ash
Slag
Silica fume
Calcined clay (LC³)
Carbon Capture & Utilization (CCU):
Injecting CO₂ during mixing (e.g., CarbonCure)
Geopolymer Concrete:
No Portland cement; made from industrial byproducts.
Carbon-Negative Additives:
Biochar or mineralized CO₂ materials.
Efficient Mix Design:
Optimized water-cement ratio
High early strength for thinner elements

🔄 Synergy Between Recyclable and Low-Carbon Approaches
Recycled aggregates help avoid virgin material use.
Using SCMs both reduces carbon and increases durability.
Designing for reuse lowers lifecycle carbon footprint.
📉 Environmental Benefits
Up to 60–80% lower CO₂ emissions (depending on mix)
Reduced landfill waste
Lower embodied energy.

👉Footing near existing adjacent footing

👉Footing near existing adjacent footing

💫When new foundations are constructed, the foundations of existing adjacent old structures are likely to be affected due to undermining by excavations, vibration, etc.

🏷The intensity of damage caused to the old structure depends upon two factors:

1-    Distance between the new and old structures.
2-    Depth of new foundations.

🚧In order to avoid chances of damage to the existing adjacent old structures, the following rules are applied:

1-    The minimum horizontal distance between the two foundations should be at least equal to the width of the wider one.

2-    In case of soft soil, a line is drawn from the edge of bottom of old footing at an angle of 30° with the horizontal as shown in fig 1.37.

⏺The horizontal spacing of two footings is adjusted in such a way that the edge of bottom of new footing is not intersected by this line as shown in fig 1.37.

⏺The horizontal spacing between two footing in case of average soil is adjusted by keeping angle of inclination as 45° as shown in fig 1.38.

3-    The foundation of new structure with reference to that of old structure should be located after making careful analysis of bearing capacity and settlement of soil.
