Test Methods for Natural Facing Stones – Part 3.Test Methods for Bulk Density, True Density, True Porosity and Water Absorption1 ScopeThis Standard specifies the equipment and measuring gauge, specimen, test procedures, result calculation and test report of test methods for bulk density, true density, true porosity and water absorption of natural facing stones. This Standard is applicable to the test for bulk density, true density, true porosity and water absorption of natural facing stones.2 Equipment and Measuring Gauge2.1 Drying cabinet. temperature can be controlled in the range of 105°C±2°C. 2.2 Balance. sensibility is 10mg with maximum weighing of 1000g; sensibility is 1mg with maximum weighing of 200g. 2.3 Pycnometer. capacity of 25mL ~ 30mL. 2.4 Standard sieve. 63µm.3 Specimen3.1 Specimen for bulk density and water absorption. the specimen shall be a cube with side-length of 50mm, or a cylinder with both diameter and height of 50mm; the dimension deviation is ±0.5mm. There are 5 blocks each group. The specimen shall be exempted from cracks. 3.2 Specimen for true density and true porosity. take about 1000g of clean sample, crush it into particles with size less than 5mm; split into 150g in quartering; then use porcelain mortar to grind the sample into powder that can pass through a 63µm standard sieve. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
