Air permeability specific surface apparatus Cement specific surface area tester

一、Specification

Accord with GB/T8074—2008 state standard we develop the new model SZB-9 Automatic Specific Surface Area Tester. The machine is controlled by computer, and operated by soft touch keys, auto control total test process. Auto remember the coefficient, display the Specific Surface Area value directly after testing work finished, it also can auto remember the test time.

二Technic parameter

1.Power supply voltage: 220V±10%

2．Time count range: 0.1second to 999.9 seconds

3．Time count precision: <0.2 second

4．Measurement precision: ≤1‰

5．Temperature range: 8-34℃

6．Ratio surface area number S: 0.1-9999.9cm²/g

7．Use range: use range described in standard GB/T8074-2008

三： Operate board description

uDisplay area

Is LCD screen, display area.

v Operation area

Formed with 8 keys, include 【Left】【Right】【Up】【Down】【Reset】【S value】【K value】【Enter】

四: Instrument elements

u Concrete ratio area indicate the total area of concrete powder.

v The method depended on mensurable air through in mensurable interspace and fixed thickness concrete layer, different resistance can bring different flow speed, and use this elements to test concrete ratio surface area.

w According the standard GB/T807-2008 commendatory calculate formula

S—The Ratio area of test sample, S_S— The Ratio area of standard powder, cm²/g

T—The liquid limit down times of test sample, T_S— The standard powder liquid down times, seconds.

η—The air mucosity when test sample in instant temperature, μPa∙s

ηs—The air mucosity when standard powder in instant temperature,μPa∙s

ρ—Density of test sample, ρs—Density of standard test sample, g/cm³

ε—Interspace rate of test sample, εs—Interface rate of standard test sample

In above calculate formula, the Because the standard powderεs is fixed, and is 0.5, so use the value correctly.
