BS EN 1367-4:1998 pdf download,Tests for thermal and weathering properties of aggregates – Part4:Determination of drying shrinkage.
This European Standard BS EN 1367-4:1998 specifies a method for determining the effect of aggregates on the drying shrinkage of concrete.
This standard BS EN 1367-4:1998 is based on the testing of concretes offixed mix proportions and aggregates of 20 mm maximum size.
NOTE 1 Guidance on the use of larger size is given in annex A.Precision data is not available for variations in size and for variations in the water content of the test concrete.
NOTE 2 In those cases where the drying shrinkage of a source ofcoarse aggregate only or a source of fine aggregate (sand)onlyare required,the other component to be used should be,respectively,a fine or coarse aggregate of known low shrinkage.
