1. Normal aggregates: Gravel and sand
2. Heavy aggregates: Iron ore and steel
3. Light aggregates: Expanded clay and perlite

Types of cement:
1. Rapid hardening cement: This type of cement sets and hardens quickly, making it ideal for projects that require a fast turnaround time. It achieves high strength in a short period of time.

2. High rapid hardening cement: This type of cement is similar to rapid hardening cement but achieves even higher strength in a shorter period of time. It is commonly used in projects where high early strength is required.

3. Ordinary Portland cement: This is the most commonly used type of cement and is suitable for a wide range of applications. It is versatile, cost-effective, and provides good strength and durability.

Shoring is a temporary structure used to support a building, trench, or other structure during construction or repair. It helps prevent collapse and ensures the safety of workers. There are three main types of shoring:

1. Raking shoring: Involves inclined supports that are placed against the wall being supported. This type of shoring is commonly used in situations where space is limited.

2. Dead shoring: Involves vertical supports that are placed directly beneath the structure being supported. This type of shoring is used when the structure is at risk of collapsing.

3. Flying shoring: Involves supports that are suspended from above and used to support a structure from below. This type of shoring is often used in situations where traditional shoring methods are not feasible.

Normal Aggregates:

- Crushed stone (e.g., granite, limestone)
- Gravel

Heavy Aggregates:

- Barite (barium sulfate)
- Magnetite (iron oxide)

Light Aggregates:

- Expanded clay
- Pumice

Types of Cement:

Ordinary Portland Cement (OPC):
- Most common type of cement
- Hardens slowly (typically 28 days to reach full strength)

Rapid Hardening Cement (RHC):
- Similar to OPC, but hardens faster (typically 7 days to reach full strength)

High Rapid Hardening Cement (HRHC):
- Hardens very quickly (typically 3 days to reach full strength)
- Used in situations where time is critical

Shoring:

Shoring is a temporary structure used to support an excavation or any other structure that is being constructed or repaired.

3 Types of Shoring:

- Hydraulic Shoring: Uses hydraulic jacks to support the structure, allowing for precise adjustments.
- Earth Retention Shoring: Retains soil and prevents it from collapsing into the excavation.
- Suspended Shoring: Suspends the structure from above, providing uniform support.
