Determination Of Drying Shrinkage for Aggregates

The test is developed on concretes of fixed mix proportions and aggregates of 20mm max size.

Length Comparators (Length Measuring Frames) are used to determine possible the length changes in  prisms of different size due to Drying shrinkage, Alkali Silica Reaction (ASR) etc.

The set consists of Length Measuring Frame, Steel Mould according to the related standard, Steel Inserts for mould (pack of 10) and Reference Rod. The set is available in four models; with 0,01 mm Analogue Dial Gauge, with 0.01 mm Digital Dial Gauge, with 0.001 mm Digital Dial Gauge and Heidenhain Digital Readout Unit  with 30x0,0001 mm Length Measuring Sensor which can be connected to Length Measuring Frames.

Prism Mould, 50x50x200 mm, three gang, complete with steel inserts, to determine the thermal properties and weathering of aggregates in drying shrinkage of concrete.

Length Comparator; the top beam is adjustable to suit the specimen’s length.

Analog Dial Indicator; 10 x 0,01 mm division. Digital Dial Indicator has two alternatives as 12.7 x 0,01 mm or 12.7 x 0,001 mm resolution.
