Our
New Equipments & Capabilities
Geotechnical Division has recently purchased new testing
machine/equipment to meet the RMC requirement for testing of coarse and
fine aggregate for concrete. These machine/equipment include of Micro-Deval
testing machine, Accelerated polishing machine, sand equivalent test
apparatus etc.

Geotechnical Division has
setup advance testing system for soil testing in UU, CU, CD,
Consolidation test. These testing will be operated with digital data
loggers, digital pressure controllers, testing software to run testing
automatically. The testing data can be downloaded in the loggers and
communicate with software to produce test result on line.
UD samples are sent in from
Internal CPG SI department and private SI companies.
|
 |
|
Triaxial Machine |
Geotechnical Division also
carry out Thermal Conductivity test for various type of cable trenching
works from PUB and private sector.
|
 |
|
Thermal Conductivity Apparatus |
Geotechnical Division has
capacity in testing soil-mix sample and grout core for UCS test by using
UTM with advance testing software. There are various type of samples
from tunnel projects, Jet grout projects etc send in for testing. Point
load is another common test beside UCS test.
