Soils and raw materials: The approximate bulk weight of 1 m³ of brick earth (as handled on site) is about

Introduction / Context:
Estimating the bulk weight (bulk density) of brick earth is useful for transportation planning, batching, and checking stockpiles. Brick earth is a natural, moist, silty-clayey sand mixture used for traditional brick manufacture.

Given Data / Assumptions:

• Brick earth considered in its typical workable moisture condition, not oven-dry or saturated.
• Bulk weight includes natural voids between particles.
• Site handling conditions are average, not highly compacted or loosened.

Concept / Approach:
Bulk densities for earthy materials typically range between 1500–2000 kg/m³ depending on moisture and compaction. Brick earth commonly falls near the middle of this band. Rule-of-thumb values in construction management handbooks cite about 1800 kg/m³ for practical planning.

Step-by-Step Solution:
List plausible range: 1500–2000 kg/m³ for moist earths.Select representative planning value: ~1800 kg/m³ is widely used for brick earth.Compare options: 1800 kg best matches typical practice; 1200–1500 kg are too low for moist earth; 2000 kg is the upper bound for very dense/moist conditions.

Verification / Alternative check:
Cross-check with local schedule of rates or material handbooks; many list 1.6–1.8 t/m³ for brick earth and similar soils.

Why Other Options Are Wrong:
1200–1500 kg: light for typical moist brick earth; more akin to loose soils.2000 kg and above: represent very dense, saturated, or aggregate-rich materials.

Common Pitfalls:
Confusing dry density with bulk (in-situ) density; moisture and looseness significantly affect values.

Final Answer:
1800 kg
