size of aggregate for cement block making

Different Types & Sizes of Aggregate for Concrete

11/08/2018· The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. The size range of various coarse aggregates given below: Fine gravel: 4mm 8mm. Medium gravel: 8mm 16mm. Coarse gravel: 16mm 64mm. Cobbles: 64mm 256mm. Boulders: > 256mm . TYPES OF AGGREGATE

GRADATION OF AGGREGATE FOR CONCRETE BLOCK

For a given cement aggregate ratio, block strengths theoretically should increase with an increase in the top size of the aggregate provided the aggregate is well graded and mix can be thoroughly consolidated in the machine. Almost all concrete block producers today use aggregate smaller than ½ inch although scattered reports have indicated the feasibility of using an aggregate with some

Concrete blocks sand cement blocks

Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building. The blocks may be solid, cellular or hollow. Cellular blocks have cavities with one end closed while in hollow blocks

Aggregate Concrete Blocks A Guide to Selection & Specification

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. Block dimensions should be specified in the order

Different Types of Aggregate Types of Concrete Each

Course Aggregate: Grain sizes range from 5mm up to around 9.5mm e.g. they are trapped by a 5mm sieve. A good example of a course aggregate is gravel ; Classifying aggregate by its grain size is in most cases the best method from a DIY perspective. As the majority of DIY-based jobs such as mixing cement, mixing mortar, rendering, laying driveways, laying concrete slabs etc involve the use of

• Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete. • Aggregates in any particular mix of concrete are selected for their durability, strength, workability and ability to receive finishes. • For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine

proportional to the average size of the particles in a given aggregate. The coarser the aggregate, the higher the FM. While all block mixes require at least one aggregate, a producer, for a variety of reasons, might decide to use as many as four aggregates in a mix. Such reasons include lack of well-graded aggregates nearby (and increased cost to obtain such aggregates) and the desire to pro

How to Make Concrete Blocks Manufacturing Cement

Find a Suitable Place**:** Find a wide open space, even better if it is shaded, that will work if rain is not that much in your place.The space should be wide enough to mix concrete and to pour it in mold. Make the mold: Use plywood planks and nails to make a one side open box with an inner cavity of 300mm (length) x 200mm (width) x 150mm (thick). This is the standard size of a concrete brick.
