This concrete mixer was horse-drawn and called 'Mortar Mixer'. It worked by replacing the front wheels with a large drum that held large paddles for mixing the cement. [ 3 ] 1925, at least two mixers, built 25 years ago, were still in use (serial numbers 37 and 82).
Mortar holding weathered bricks. Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colours or patterns to masonry walls.

Ready-mix concrete (RMC) is concrete that is manufactured in a batch plant, according to each specific job requirement, then delivered to the job site "ready to use". [1] There are two types with the first being the barrel truck or in–transit mixers. This type of truck delivers concrete in a plastic state to the site. [2]
As mostly no coarse aggregate is used for production of foam concrete the correct term would be called mortar instead of concrete; it may be called "foamed cement" as well. The density of foam concrete usually varies from 400 kg/m 3 to 1600 kg/m 3. The density is normally controlled by substituting all or part of the fine aggregate with the foam.
It is mainly composed of elevator, premix bin, stock bin, mixing engine, finished product warehouse, automatic packing machine, dust collector and electric control cabinet. Dry mortar mixer can be vertical or horizontal type and there are many models for choosing according to customer's actual conditions.
Portland cement blends are often available as inter-ground mixtures from cement producers, but similar formulations are often also mixed from the ground components at the concrete mixing plant. Portland blast-furnace slag cement , or blast furnace cement (ASTM C595 and EN 197-1 nomenclature respectively), contains up to 95% ground granulated ...
A pugmill, pug mill, or commonly just pug, is a machine in which clay or other materials are extruded in a plastic state or a similar machine for the trituration of ore. [1] Industrial applications are found in pottery, bricks, cement and some parts of the concrete and asphalt mixing processes. A pugmill may be a fast continuous mixer.
