Question 1

What is छिड़काव कंक्रीट (Shotcrete)?

Accepted Answer

Shāṭakriṭ (Shotcrete), or छिड़काव कंक्रीट, is a composite cementitious material [1] pneumatically projected onto a surface. Its modern formulation typically comprises Portland cement, aggregates sourced from regional quarries (e.g., Deccan Plateau basalt), and admixtures. While a relatively recent construction technique, its application echoes traditional *vajralepa* (diamond plaster) techniques used in reinforcing structures.

Compressive strength ranges from 30-50 MPa, with a density of 2200-2400 kg/m³. High application velocity yields strong bond strength. Porosity and permeability are application-dependent. Shāṭakriṭ is used for slope stabilization, tunnel lining, and structural repair, including conservation of Indic heritage sites. Restoration projects often employ Shāṭakriṭ to reinforce weakened *ishtika* (brick) or *shila* (stone) masonry, addressing degradation from weathering and biological growth. Conservation requires careful material selection to ensure compatibility with existing *vastu* (structure) and prevent further damage.

Question 2

What type of material is छिड़काव कंक्रीट (Shotcrete)?

Accepted Answer

छिड़काव कंक्रीट (Shotcrete) is classified as Composite Material, Cementitious Material, Concrete. Key properties include Compressive strength: 30-50 MPa (after 28 days), Density: 2200-2400 kg/m³, High bond strength due to application velocity.

Question 3

Where is छिड़काव कंक्रीट (Shotcrete) used?

Accepted Answer

छिड़काव कंक्रीट (Shotcrete) is commonly used in South Asia, India. It is sourced from Cement manufacturing plants, Aggregate quarries, Admixture suppliers.

Question 4

How is छिड़काव कंक्रीट (Shotcrete) used in heritage architecture?

Accepted Answer

छिड़काव कंक्रीट (Shotcrete) is used for Stabilizing slopes, Reinforcing retaining walls, Lining tunnels, Repairing concrete structures, Strengthening existing masonry in heritage architecture. It is found in 1 heritage sites.

Question 5

What are the conservation considerations for छिड़काव कंक्रीट (Shotcrete)?

Accepted Answer

Conservation of छिड़काव कंक्रीट (Shotcrete) requires attention to Susceptible to cracking if curing is inadequate and Requires skilled application for proper compaction and bond. Proper maintenance is essential for preserving heritage structures using this material.
