In block wall construction (CMU) "bond beam" refers to a course (horz row) that is filled with grout and steel reinforcement. I have not heard the term used in residential construction.
Hi there, I would use a 5-1 ratio of sand to cement and use a good mortar plastisier. Use plastering sand and mix well. Throughly soak the wall first and apply a light coat (scratch coat) Leave this to dry for a while and before it has completely dried, get the final coat on. Too much water on the wall will result poor bond between the Brick masonry and the plaster on account of lack of suction which is the primary mechanism by virtue of which the Cement Plaster will remain in position against the gravitational force.
A masonry beam is more often called a "bond beam." This is where a block is cut or manufactured with a slot to lay down one or two pieces of rebar down inside the block horizontally. The blocks are filled with grout and this adds horizontal strength to the wall by tying the vertical cells that are filled with grout to the horizontal cells that are filled with grout, creating a grid making the wall much stronger. www.masonryworktools.com
ACI 301-10 3.3.1.1, in part, states that reinforcement shall be free of material which could be deleterious to bond. Some limited testing shows that certain kinds of bond breakers are not deleterious to bond between concrete and steel reinforcement. Other bond breakers (membrane forming types) undoubtedly will interfere with bond, and some materials may result in accelerated corrosion of steel reinforcement.

So a network covalent bond or macromolecular bond is basically a bunch of covalently bonded atoms. Imagine a diamond structure or crystal structure that keeps expanding but a model only shows a building block of the substance. So like a brick wall to a brick.
Masonry bond refers to the pattern of the bricks within a wall. The most basic is running bond, where all brick within a wall are stretchers (laid with the long, narrow face outward). In English bond, a course of stretchers is followed by a course of header brick, which are laid with their longer edge going back into the wall. This gives the wall a horizontal striped pattern. In Flemish bond, adjacent bricks in each course alternate between stretcher and header, and the next course is reversed. This gives the wall a diagonally striped pattern. I'm less certain of this next (because these bond patterns are expensive and rarely used in brick veneer construction), but I believe single vs double Flemish bond refers to the thickness of the wall. Single is actually two wythes of brick (an inside and an outside wythe) where double is three or more wythes thick. This allows the pattern on the inside to be more independent of the outside pattern, and simplifies corners and masonry openings.
A coralent bond (otherwise known as English bond) refers to a style of masonry or brickwork that appears as an inlocking pattern.
A covalent lattice is a type of bond that occurs between non-metal atoms. The atoms bond to an certain number of atoms which bond to more atoms etc. Examples include graphite, diamond and silica.

English bond use a lot of facing brick, but it stability is higher than stretches bond.
seeing how it has a CRYSTAL STRUCTURE I would say ionic bond.

A king closure is a brick cut to bond in a corner of brickwork, a brick with a corner cut off.
