Stone's physical performance index
2010-02-12 by LeiYi Trading
The stone physical performance index is a stone very important index of safety, test results of stone allows the architect or engineer to know the stones are designed to ensure that the structure is strong enough, and it meets the engineering design parameters, it is safe to use.
Granite, marble blocks and standards slabs are both have strict specific index, which reflect the natural stone material itself is an important index.
Physical performance index usually refers to the bulk density, water absorption, dry compression strength, bending strength 4, do this four experiments require 5 working days required to provide two kinds of specifications, samples, respectively 50x50x50mm 6 blocks, and 250x100x20mm 6 blocks, these four trials generally only in the professional quality inspection centers.
bulk density and water absorption
The trial, first said the stone dry weight of the specimen; and then the specimen immersed in water saturated, saying that re-floating in the water; be removed from the water saturation in the air, said the wet weight. By comparing the dry weight of stone specimen, saturated wet weight and its floating in the water weight, you can calculate the water absorption of stone specimen weight and volume density of stone specimens.
Compressive Strength
stone in the humid state of the compressive strength and drying condition is different from the direction of stone by the Dutch grain direction parallel to the compression strength perpendicular to grain direction are also different, stone after the compressive strength, freeze-thaw cycles will produce change, these are determined by the type of stone. Therefore, the compression strength of stone shall be in all the five kinds of states of: wet and dry, by the Dutch and the perpendicular to the direction parallel to the direction of stone texture, freeze-thaw cycles of the compression strength.
Flexural strength
The trial is a large stone from a panel of stone were cut to a quarter-point loading test piece, and gradually increase the load until the destruction of the sample, recording the maximum load imposed and calculated destruction of the sample when the bending stress.
We show a series of stone physical performance index, and along with Zhangpu black G685 basalt test reports for you to reference.
