Mortars are Piled With Bricks

To make any kind of brick work complete it must be plied together with mortar. The way in which the bricks are bonded together is vital to the strength of the overall structure. Concrete mortars contain aggregates of more than 5mm where as mortar contains aggregates less than 5mm.

The mixture has to be mixed together with clean water before it is ready to use. Normal bricks should be laid on a bed of mortar at least 3/16" and no more than 3/8" thick. For a course of bricks 8 courses high, your mortar should not exceed 2" in total. With pressed bricks being smoother a mortar joint of 1/8" can be used. For rough stone work a mortar with rough sand can be used, but for pressed brickwork it must be very fine sand.
Slaked lime is used to make lime mortar. The mortar is made by mixing sand with slaked lime at the proportion of 1 part lime to 5 parts sand. There are two types of lime used in lime mortars, one that sets and hardens by the reaction with the air (non-hydraulic) and one which sets by reaction to the water (hydraulic).
Non-hydraulic lime is made from pure calcium carbonate, or chalk or limestone. This is burned in a kiln to create calcium oxide or quicklime. When this is slaked with water it takes on another form as calcium hydroxide. Calcium hydroxide reacts with the air to set. This is what sets the brickwork together and creates the strength.
Hydraulic Limes. Calcium carbonates naturally occur but can include some impurities. It is these impurities which when burned in a kiln create the calcium silicates or aluminates that react with water to set. Enough water is added to the mixture to create calcium hydroxide powder form. The hydraulic lime is then graded depending on their overall set strength.
Weather Struck and Cut Pointing in Brick Making
Similar to the previous weather struck joint, except the bed joints are neatly trimmed using a Frenchman or pointing trowel. The most popular joint used today, where the joint bed is slightly rounded inwards. The mortar should not be pressed in too hard. The tool needed for this job is a rubber hose block making machines diesel cement mixers for sale, an old type bucket handle.
This finish of this joint is flush with the brick work concrete mixing batch plant for sale, smoothed off with a rag. This finish should only be used for brickwork above water level. This Finish of this joint is recessed. The mortar is formed to a consistence depth of approximately 5 mm. This joint should only be used with a frost resistant brick and is not recommended where the brickwork could be exposed to severe wind driven rain.

This type of joint should be used when the bricks have become uneven over time due to weathering. The joint is pointed by filling the perp joint first and then the bed joint which would be shaped by placing the trowel on the perp joint and angling it downwards to create a smooth finish.
