Remember, the lighter the concrete, the weaker the block. Step 2 - Mix Water. To begin the process, add five gallons of water to the mixer. If you are planning on changing the color of the blocks, then insert colorants or other additives at this time. Once everything is thoroughly mixed, proceed to the next step.

The square-shaped concrete column block is specially designed to form the exterior casing of a cast concrete column. Like the standard core-fill block, the column block's interior is hollow.
There are several sizes, however the one most commonly referred to is the large, rectangular block with two holes - usually used for building foundations. This type of block m…easures 8" x 8" x ...
To define the geometry of a hollow block like this is very cumbersome using an analysis program by finite elements. For this reason, a three-dimensional parametric design program was used in order to make one hollow brick.
The first hollow concrete block was designed in 1890 by Harmon S. Palmer in the United States. After 10 years of experimenting, Palmer patented the design in 1900. Palmer's blocks were 8 in (20.3 cm) by 10 in (25.4 cm) by 30 in (76.2 cm), and they were so heavy they had to be lifted into place with a small crane.
There are different types of concrete blocks interlocking, hollow, solid and half hollow manufactured in high or low density. One of the most common ways to build a retaining wall of concrete blocks is to stack them on top of one another and secure them with pins, clips or interlocking edges.
Types of Hollow Concrete Blocks: Stretcher block; Corner block; Pillar block; Jamb block; Partition block; Lintel block; Frogged brick block; Bull nose block; Concrete Stretcher Blocks. Concrete stretcher blocks are used to join the corner in the masonry. Stretcher blocks are widely used concrete hollow blocks in construction.
Hollow Blocks can be crafted using a large number of different combinations of other Hollow Blocks. Any combination of the Hollow Blocks below will work, provided they add up to at most 7/8, and all materials used are made of the same material.
Blocks with cracks and corners crumbling away when handled suggests poor quality. If the CHB breaks when dropped from head height, don’t use it or other blocks in the same batch. Construction: Dampen CHBs before laying as dry masonry absorbs water from the cement, weakening the joint.
We offer two sizes of hollow concrete block to complement our range of solid dense blocks. They are manufactured to BS EN 771-3 using Class 1 limestone aggregates. The blocks are available in a standard face size of 440 x 215mm and in thicknesses of 140mm and 215mm in a standard finish (suitable for rendering).
A standard concrete block is 7 5/8 in. wide by 7 5/8 in. tall by 15 5/8 in. long. With a 3/8-in. masonry joint, that equates to 8-by-8-by-16 inches when the block is installed in a structure. To reduce weight, concrete blocks usually have two or three hollow cores taking up about 50 percent of the block's volume.
Hollow blocks are available in many different sizes. In the United States, the standard size is 20 centimeters by 20 centimeters by 41 centimeters or 8 inches by 8 inches by 16 inches. In the United Kingdom and Ireland, they use a different standard size, which is 44 centimeters by 21.5 centimeters by 10 centimeters or about 17.3 inches by 8.5 inches by 3.9 inches without the mortar joints.
