What causes honeycombing?

Honeycombing is produced pathologically by the dissolution of alveolar walls with the formation of randomly distributed airspaces that are lined by fibrous tissue. Honeycombing represents an end-stage lung that is destroyed by fibrosis.

What is peripheral honeycombing?

Honeycombing is a CT imaging descriptor referring to clustered cystic air spaces (between 3-10 mm in diameter, but occasionally as large as 2.5 cm) that are usually subpleural, peripheral and basal in distribution.

What is Microcystic honeycombing?

What is honeycombing in concrete?

What is reticular fibrosis?

Reticular shadowing – Fibrosis Pulmonary fibrosis causes reticular (net-like) shadowing of the lung peripheries which is typically more prominent towards the lung bases. It may cause the contours of the heart to be less distinct or ‘shaggy’ Chest X-rays can be helpful in monitoring the progression of pulmonary fibrosis.

How do you remove honeycomb from concrete?

  1. Remove loose concrete or loosened aggregate by hammer or wire brush.
  2. Clean any dirt or loose material from the area.
  3. Wet the cleaned area before applying the repair material.
