solid masonry or 8-inch thick hollow-core block is required. The above-grade masonry walls of the single-story Ohio case study home were built with 8-inch thick hollow-core block. The above-grade masonry walls of the two-story Minnesota home used 6-inch thick hollow-core blocks with the addition of vertical steel reinforcement bars.
Hollow concrete blocks can be used for (a) exterior load bearing walls, (b) interior walls, (c) Panel walls, (d) columns, (e) retaining walls and (f) compound walls. In view of their versatile uses and properties, hollow concrete blocks are in demand not only for constructions but departments/agencies engaged in construction including ...
Only 4 block types are required: 20.45, 20.48, 20.21 and 20.61. For the bottom course, a 20.45 block is used to avoid a mortar joint through the wall. The body of the wall is built using 20.48 blocks layed in running bond. As these blocks have open ends, they form large cavities down which concrete can be easily poured into.

This research paper reports the results of vertical load test on nine full scale double leaf brick cavity walls. Masonry mortar 1:1:6 (cement: lime: sand) was used as a binding material in the construction of wall. Two types of ties, brick and standard steel ties were used to connect the leaves across a 50 mm cavity.

Hollow blocks manufacturing process pdf A concrete block is a block of concrete. To increase the quality of the blocks you need to apply vibration and force to make the mortar as compressed as possible. A specific block is a generic name and includes different types of blocks. Below you can see some examples of concrete blocks. 1.

The concrete block — hollow (open or closed cavity) or solid shall be referred to by its nominal dimensions. The nominal dimensions of the concrete blocks are given below: Length : 400, 500 or 600 mm. Height : 200 or 100 mm. Width : 50, 75, 100, 150, 200, 250 or 300 mm.
The blocks are available in a range of colours, textures, finishes and shapes. See back for Special Block shapes. Dimensions Face sizes/co-ordinating dimensions Aggregate concrete blocks are typically available in two standard face sizes (length x height) of 440 x 215mm and 390 x 190mm. Other face sizes are available to aid manual handling.
Filling the cores of the block with grout or other non-combustible material will increase the ire resistance. Applying plaster or gypsum wall board will also increase the ire resistance. Estimated Fire Resistive Periods of Walls and Partitions of Hollow Concrete Masonry Units
