How Many Blocks Are needed?Different Types of BlocksHomemade BlocksFor More InformationAs a general rule, 2-year-olds should have at least 200 blocks available to them, 3-year-olds should have at least 300, and children 4 years old and up should have at least 400. Ideally, each class should have a variety of shapes, sizes, and textures. Different blocks and building materials can be used for different purposes. If you are in a child care center that cannot afford several different types of blocks in each classroom, a great way to get variety is to supply each classroom with a different type and rotate them How to calculate materials for different-ratio concreteThe easiest way to estimate concrete materials for different unit is, apply the above result as percentage. That means, Cement content for 100 unit of 1:1.5:3 ratio concrete is 28% (unit will be as concrete unit), Sand is 42% and Stone chips is 84%.
Aggregate Concrete Blocks A Guide to Selection & Face sizes/co-ordinating dimensions Aggregate concrete blocks are typically available in two standard face sizes (length x height) of 440 x 215mm and 390 x 190mm. Other face sizes are available to aid manual handling. To obtain the co-ordinating dimensions add the specified joint thickness (normally 10mm) to the height and length of the block.
CoverAnchorage and Lap LengthsTension LapsCurtailmentThe nominal cover should generally be specified by the designer (See:How to Design Concrete Structures using Eurocode 2:Chapter 2, Getting Started). The nominal cover should be shown on the drawings and should refer to the reinforcement nearest to the surface of the concrete e.g. the links in a beam. The cover to the main bar should be at least equal to the size of that bar, plus the allowance for deviations, cdev which is usually 10 mm depending on the quality assurance. In high exposures nominStandard Brick Dimensions Based on Different Codes4. British Standard . The standard dimension of a modern brick is 215 × 102.5 × 65 in mm (length x depth x height) dimension. 5. Australian Standard . The standard brick size based on Australian Standard AS 4455 is 230 x 110 x 76 mm (length x width x height). However, some bricks have work sizes such as 290 x 90 x 90 mm and 290 x 90 x 50 mm.

Steel construction products - SteelConstructionfoProfiled sheeting for floors is primarily intended for use with concrete to create a composite floor slabs. There are two broad classes - shallow profiles, up to about 175 mm deep, which are used for short span applications, and 'deep decking', typically 225 mm deep, for longer spans.
Nominal brick dimensions are used in modular construction and are the specified size plus the width of the mortar joint. Most bricks are manufactured so that the nominal sizes fit into a grid of 4", which coincides with the modules of other building materials such as doors, windows, and wood components.
