GRADATION OF AGGREGATE FOR CONCRETE BLOCK

GRADATION OF AGGREGATE FOR CONCRETE BLOCK . Although numerous papers have been written concerning the proper gradation for concrete mixes they have generally dealt with plastic mixes and very little published information is available on the subject dealing specifically with the minus zero slump mix as used in concrete block production.

Ideal grading curve for q 0.27 and actual overall particle size distribution for the high performance concrete HPC Self-compacting concrete is highly flowable and is very sensitive to overall gradation and the water content. A typical mixture proportion of SCC is given in column 4 of Table 2.

GRADATION OF AGGREGATE FOR CONCRETE BLOCK

Excessive inter-particle voids will be present in a concrete block even if produced from an optimum graded aggregate if the mix is made too dry. Usually excessively dry mixes will be harder to compact give higher block porosity poorer green block stability and lower compressive strength. For a particular block mix maximum block density minimum voids and strength are obtained by using the maximum water content will be limited by the tendency to produce a smeared block

Recycled Aggregates for Green Concrete

In concrete aggregates act compositely in the combined state. Grading envelopes given in standards such as ASTM 33 when plotted as a combined grading curve often s how deficiencies of certain particle sizes. These lead to gaps that represent less than ideal combined grading Alexander and Mindess 2005. For this reason the Fuller distribution was

Grading of Aggregates in Concrete Spreadsheet CivilWeb

Importance of Grading of Aggregates in Concrete The importance of grading of aggregates in concrete is mostly related to the workability of the fresh concrete mix and the associated water and cement contents. The combined grading of the aggregates determines the ratio of aggregates and cement paste contained within a particular volume of concrete.

Curve No. 1 represents the coarsest grading in each set of curves. These gradings are compara tively workable and can be used for mixes with low watercement ratio or for rich mixes. However it should be ensured that no segregation takes place. At the other extreme curve No. 4 represents a fine grading. It will be cohesive but not very workable.
