Vertical reaction pa sinθ 600 x π x 1 2 2 x sin45 4 480 kn.
The width of the thrust block is considered as 2250mm and length consider as 2000mm.
Rounded aggregates give a more workable mix.
Consider the arrangement of the thrust block as shown in the above figure.

Into concrete blockwork performance.
It includes guidance on the safe handling of blocks for both the specification and sitework phases of projects.
Concrete blocks are formed in steel moulds using relatively stable materials enabling the size of individual units to be controlled to within small tolerances.
Storage aggregates should be stored where they will stay clean separated from other materials and dry.
The code for concrete masonry units as nzs4455 1 permits a general tolerance of 3mm on the overall dimension of each unit.
Angular aggregates make concrete harder to place work and compact but can make concrete stronger.
A concrete masonry unit cmu is a standard size rectangular block used in building construction is 2185 1 2005 3 10 solid block a block which has solid material not less than 75 percent of the total volume of the block calculated from the overall dimensions.
