How should cement be stored?

In a dry weatherproof shed, raised 150-200 mm, 300 mm from walls, not more than 10 bags high

On bare ground, stacked 20 bags high

What does FIFO ensure?

Oldest stock is issued first, avoiding deterioration

Sand and aggregate should be stored on:

a clean, hard, dry, sloping platform with partitions

Which is a good storage site consideration?

Firm, dry, well-drained ground near the work and access road

Storing and stacking of civil engineering materials

Short answer

Store materials on firm, dry, well-drained ground, protected from weather and theft, with FIFO access. Cement in raised sheds max 10 bags high; steel on platforms; bricks neat stacks ~1 m; aggregates on hard clean platforms; timber ventilated; hazardous items separate. Proper stacking prevents damage, wastage and helps counting.

Explain the main considerations necessary in the storing and stacking of civil engineering materials.

Proper storing preserves quality, avoids wastage and keeps materials ready for use. Main considerations:

General considerations

Location: near the work and access road, on firm, dry, well-drained, level ground, away from the working area and traffic, with enough space for turning vehicles.
Protection from rain, sun, wind, moisture, fire and theft; fencing, security and lighting.
Accessibility and sequence: use first-in first-out (FIFO) and keep items of different grades apart; labelling.
Safety: keep fuel, explosives, bitumen, and paints separate and away from fire.
Records: stock register and regular inspection.

Specific materials

Material	Storage / stacking
Cement	In a dry weatherproof shed, floor raised about 150-200 mm on planks, 300 mm away from walls, stacked not more than 10 bags high (7 bags if kept for long), in rows with passage for FIFO and covered with tarpaulin
Steel bars	On raised platforms (sleepers), by diameter and length, covered to avoid rust, free of oil and mud
Bricks / blocks	On firm ground in neat stacks, 1 m wide and about 1 m high (not more than 2 m), in groups of 50-100, with passage
Sand, aggregate	On a clean, hard, dry, sloping platform with partitions to avoid mixing; not under trees; covered in rain
Timber	Raised, ventilated, stacked with spacers, protected from sun and termites
Tiles, glass	Boxed, under cover, stacked on edge in a dry place
Bitumen, paints	In a ventilated, cool, fire-safe place; drums upright
Pipes	Supported on level ground, spigot and socket alternately, with no sagging

Good stacking prevents damage, wastage and accident, and helps counting and issue.
