Building decoration stone material quality and performance test method

1. Why to want to make stone of physical, chemical performance testing, including what content?

Stone material is applied to building each aspect, endures natural, human conditions are very different, the stone may encounter various conditions of artificial inductive together, trying to prove some stone performance rions design requirements for design, user puts forward scientific reference marble. So put forward a set of the test content for stone, become the physical and chemical testing stone facing the natural stone the test method.

Stone physics, chemistry test method has 11 aspect content.

1) drying, water saturation, freeze-thaw cycle compression strength test method;

2) drying, water saturation bending strength test methods;

3) volume density, true density, really porosity, bibulous rate test methods;

4) abrasion resistance testing methods;

5) XiaoShi hardness testing methods;

6) acidoresistant test methods;

7) detection plank guajian combination unit hang outfit strength test method;

8) using the uniform static pressure differential detection stone hang outfit system structure strength test method;

9) stone chemical composition (each mineral content composition) analysis;

10) stone radioactive evaluation;

11) stone comprehensive evaluation system: including adornment performance evaluation, green stone index, green stone comprehensive evaluation system, and comprehensive evaluation system use method.

Of course as stone (including artificial stone), it still has such as tensile strength, thermal expansion coefficient, specific heat capacity, thermal conductivity, volume resistivity, dielectric constant, dielectric loss Angle tangent, dielectric strength etc many index, is stone in chemical, mechanical, geology, etc are used requirements. But as architectural decoration stone generally as long as satisfies the 11 content, especially to meet the requirements in item before 10 can be used.

2. The natural stone drying, water saturation and freeze-thaw cycles on the compression strength test should be after what preparation

As a kind of natural stone material of building materials, widely used in many fields, use the natural conditions facing from high temperature to cryogenics repeatedly circulation, to make stone in the future use of not in these conditions occur, loss of fracturing, it will have to use value artificial simulating natural conditions in advance to test the stone. The natural stone drying, water saturation, the compression strength of natural freeze-thaw cycle test is one of them. To make this test should do as follows prepared.

(1) equipment and measuring tool

Tester; Spherical support and value is relative error less than + 1%, test damaging loading in the Slate should be within 20% ~ 90% of material testing machine.

Vernier caliper: read values for 0.01 mm.

Vernier caliper: read values for 0.01 mm.

Universal Angle scale: precision for 2 routines.

Drying oven; At 105 ℃ temperature control plus or minus 2 ℃ scope.

Can be controlled in reefer: temperature 20 ℃ + 2 ℃ scope.

(2) stone specimens

Size: the cube or 650mm side 50 x 50 cylinder.

Quantity: each test sample preparations should 5, 5 for a group of statistical data. Dry, water saturation, freeze-thaw cycles to the compression strength test after 15 sample; If undertake drying, water saturation, freeze-thaw cycles of vertical bedding test after parallel bedding again compressed strength test preparation 30 samples is required.

Sample shall indicate bedding direction: some stone has obvious bedding direction, application in bedding place color pen evoke. Such as granite, marble
