Concrete Blocks Technical Data Short Description Concrete block construction has gained importance and has become a valid alternative to fired clay bricks. The essential ingredients of concrete are cement, aggregate (sand, gravel) and water. Concrete blocks are produced in a large variety of shapes and sizes. They can be produced

This research and compilation, highlights the use of different materials that are used for construction of structures ranging from housing complex, bridges and roads to skyscrapers and monuments. The optimum usage of such building materials and their
Hollow concrete is an important addition to the types of masonry units available to the builders and its use for masonry is constantly increasing. OBJECTIVE 1. To study the behaviour of the cement concrete hollow blocks by adding Fly Ash. 2. To study the compressive strength of the CC hallow blocks to replacing cement by fly ash. 3.
Fig. 1 Placing Hollow Concrete Blocks 3. MANUFACTURING PROCESS Cement concrete blocks can be solid (dense) or hollow. Besides different sizes and designs can be given to the blocks. The blocks are made in the sizes of 12x8x4quot;; 12x8x3quot;; 12x8x6quot;, etc. Firstly cement, stone chips, sand, etc are mixed in the ratio of 1:6 or 1:12. This mixture is

Hollow concrete blocks are substitutes for conventional bricks and stones in building construction. Concrete Block Making Machine 1 No Cement Mixer with motor 1 No. Ramming moulds of following sizes (a) Cavity 100 x 200 x 400mm (b) Cavity 150 x 200 x 400mm
The production of Hollow Concrete Blocks. a Aggregates, Sand, Gravel, Red Ash: should be clean, stored separatly close to the mixing plant. All aggregates used for production have to be approved by an. independant concrete labatory! b Water: mustbe clean and free of unpurifications. c Cement: Portland Cement ( OPC ) shall be used as a binder
Aspdin developed portland cement, which became one of the key components of modern concrete. The first hollow concrete block was designed in 1890 by Harmon S. Palmer in the United States. After 10 years of experimenting, Palmer patented the design in 1900. Palmer''s blocks were 8 in ( cm) by 10 in

cement concrete hollow blocks. The machine consists of an automatic vibrating unit, a lever operated up and down metallic mould box and a stripper head contained in a frame work. 5 Wooden pallets are kept on the vibrating platform of the machine. The mould box is lowered on to the pallet.
annum. In the beginning of the project cycle, the throughput has been assumed as 70% for REBs. Proposed Products The project proposes to produce perforated bricks/blocks with perforations varied from 1020%, modular bricks and tiles. Knowhow and Compliances The technical knowhow for machinery would be provided by the supplier who
800000 Nos. of cement concrete hollow blocks of size 100X200X400 mm. At 75% utilisation of the capacity, productions of 600000 Nos. of blocks have been taken into consideration. Cement concrete hollow blocks are usually of the following three dimensions: 100X200X400 mm, 150X200X400 mm and 200X200X400 mm. Although
HOLLOW AND CEMENT CONCRETE BRICKS 1. INTRODUCTION: Cement concrete dense/ hollow bricks and blocks are very popular and are extensively used in building construction throughout the country because of the many advantages such as durability, strength and structural stability, fire resistance, insulation and sound absorption it Possess.
The ratio of cement, sand and stone chips (metal) in the raw material mix determines the properties of hollow concrete blocks. A ratio of 1:3:6 (cement : sand : metal) confers higher strength, while a ratio of 1:5:6 can be employed for normal load bearing construction. The water to cement ratio is usually 0:4:1.
They are the standard sized rectangular hollow blocks made of cast concrete of high or low density. For highdensity blocks, Portland cement and aggregate, usually sand and fine gravel are used as a raw material. For low density blocks, industrial wastes, such as fly ash or bottom ash are used as the primary raw materials and are often called cinder blocks /breeze blocks in different parts of
