cement takes up moisture and hydrates, making it unfit for use. Paper bags are somewhat resistant to atmospheric moisture, but do not provide adequate protection for long periods of storage. Material stored in bulk is less damaged by atmospheric moisture because the ratio of exposed surface to volume is much smaller than in sacked product.
