Wood has remain good structural material. To improve durability and appropriate use of wood, research works are going on wood concrete composites. Use of nails, grooves in wood will help in improving bond between wood and concrete. Bond stress between wood and concrete or mortar depends on surface conditions, moisture content in wood, water cement ratio, coating on wood if any, dowel action of nails if any. Cement mortar of concrete can be used to improve durability or retrofit wooden structures. Therefore the question is how to improve bond between wood and concrete.
