Concrete Hollow Block Federal Democratic Republic of Ethiopia WASH facilities, it is very important to understand the special context in The mass production of various kinds of concrete masonry blocks ,i.

Ethiopia, Milutin Milankovitch started production of hollow reinforced-concrete slabs.A concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit CMU. A concrete block is one of several precast concrete products used in construction. The term precast refers to the fact that the blocks are formed and hardened before they are brought to the job site.

Most concrete blocks have one or more hollow cavities, and their sides may be cast smooth or with a design. In use, concrete blocks are stacked one at a time and held together with fresh concrete mortar to form the desired length and height of the wall. Concrete mortar was used by the Romans as early as B. During the reign of the Roman emperor Caligula, in A. Much of the concrete technology developed by the Romans was lost after the fall of the Roman Empire in the fifth century.

It was not until that the English stonemason Joseph Aspdin developed portland cement, which became one of the key components of modern concrete. The first hollow concrete block was designed in by Harmon S. Palmer in the United States. After 10 years of experimenting, Palmer patented the design in Palmer's blocks were 8 in Byan estimated 1, companies were manufacturing concrete blocks in the United States. These early blocks were usually cast by hand, and the average output was about 10 blocks per person per hour.

Today, concrete block manufacturing is a highly automated process that can produce up to 2, blocks per hour. The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs lb In general, the concrete mixture used for blocks has a higher percentage of sand and a lower percentage of gravel and water than the concrete mixtures used for general construction purposes.

This produces a very dry, stiff mixture that holds its shape when it is removed from the block mold. If granulated coal or volcanic cinders are used instead of sand and gravel, the resulting block is commonly called a cinder block. This produces a dark gray block with a medium-to-coarse surface texture, good strength, good sound-deadening properties, and a higher thermal insulating value than a concrete block.

A typical cinder block weighs lb This study targets to assess the feasibility of using crushed sandstone in and around Adigrat as a sand replacement material in hollow concrete block. The study was conducted by taking samples from three types of sandstone, categorized based on their colour as white, red and light red.

The physical and chemical properties of the sandstone were studied. The sandstone was then used to prepare sample blocks which were then tested for density and compressive strength. The test results on the blocks showed that the blocks manufactured using sandstone as a replacement of construction sand, have all the strength and density requirements specified in ESat least as a non-load bearing wall making material. From the three sandstone categories, the white sandstone has produced the best results with relatively higher compressive strength and density.

It can be concluded from the study that the crushed sandstone around Adigrat can be readily used as a replacement for sand in hollow concrete block, as far as the production procedures in this study are followed. The sandstone may also serve as a sand replacement in concrete production with further study on it. Commercial sand production from the sandstone could also be taken as a potential solution for sand shortage with further study on cost feasibility. Location of Repository.

How to Start Hollow Bricks Manufacturing Business

Inform yourself using the interactive step by step system, as to how a concrete block is produced from various raw materials. Quality from the very beginning - that is our philosophy. The use of comprehensive and effective dosing systems guarantee optimum and efficient delivery of raw inputs for example, sand, cement, water, additives to cement mixers. Using the tried and tested Masa concrete mixers results in reliable and high-quality mixing.

Easy maintenance and durability makes this Masa concrete mixer a worthwhile long term investment. Another important part of the manufacturing process is the individual color design of paving stones or other concrete stones. It can be achieved in both simple and complex multi-color systems for main and face concrete.

Depending on the system layout, the Masa concrete mixers are positioned directly over the concrete block machine or outside the plant. The transport of the concrete from the outside concrete mixing plant to block machine is most frequently by use of a bucket conveyor system although other systems can be utilized. According to customer requirements different bucket conveyer variations are available.

The heart of every concrete block making plant is undoubtedly the concrete block making machine. With the right choice you can score on the market in the long run.

Offered especially for the production of concrete curbstones for "British Standard" with a purely hydraulic compression system, Masa also offers concrete curb presses. The Masa wet side transport ensures that the freshly-produced products are conveyed gently and without loss of quality from the block making machine to the elevator.

At the same time Masa does not lose sight of the importance of quality control. As proven standard solution, Masa offers a walking beam conveyer with servo drive, providing a low-vibration transport of fresh products. However, Masa can also supply alternative transport systems. Ahead of the actual conveying path is the lowering rocker which can also be used for doubling of production pallets. In the high speed S-package the lowering rocker is combined with a V-belt conveyor.

It is synchronized with the production pallet feed of the block making machine. The transportation of fresh products into the curing area and the subsequent removal and transfer of the cured products require an intelligent integration of various system components. The Masa elevator collects production pallets with fresh products. Production pallets are cyclically transported upwards. Once the elevator has reached a defined limit, production pallets are picked up by finger car and transported to one of the curing chambers.

The finger car itself consists of a track-bound undercarriage with or without turning device available, depending on plant layout and an upper structure. After the finger car has accurately positioned in front of the curing chamber, low-vibration transfer into the curing chamber takes place. The stocking process of the products into the curing chamber takes place on a user prescribed basis. After curing, the production pallets are again taken up by the finger car and either transported first to the intermediate finger car optional or directly to the lowerator.
