IJUE MAABARA YA KUPIMA VIFAA VYA UJENZI YA NHBRA

Maabara ya NHBRA imegawanyika katika sehemu kuu mbili ambazo ni:
  • Wet laboratory
  • Dry laboratory
Lengo la kupima ubora au uimara wa vifaa vya ujenzi au kufanya majaribio mbalimbali katika maabara ni kuhakikisha kuwa vifaa vinavyotumika kwa ujenzi vinafikia kiwango cha chini cha ubora unaohitajika (minimum quality/strength requirement) kilichowekwa.

MAJARIBIO MBALIMBALI:

Majaribio ya udongo (soil test)
  • Kupambanua aina za udongo (soil classification)
  • Kushindilia (compaction related tests)
  • Upitishji maji na Uimara (compressibility, permeability and durability tests)
  • Jaribio la eneo la kazi (in-situ tests)
  • Shear strength tests
  • 
    Mashine ya kupima uimara wa udongo
Matofali na zege (blocks, bricks and concrete)
  • Mkandamizo (compressive strength)
  • Mchanganyiko (concrete mix design)
  • Kunyonya maji (absorption test)
  • Rebound hammer
  • Slump test
  • 
    Mashine ya kupima uimara wa zege na matofali
Aggregates
  • Kusagika (aggregates crushing value)
  • Kupondeka (aggregates impact value)
  • Kunyonya maji (water absorption)
  • Uimara kwenye msuguano (Los Angels abrasion value)
  • Uzito (bulk density)
  • Mabaki ya mimea (organic impurities)
Nondo
  • Kuvutika (Tensile strength)
  • Kukunjika (bending test)
  • Kukunjuka/kukunjua (rebending test)
Mbao (timber)
  • Unyevunyevu (moisture content)
  • Kukunjika (bending test)
Nachukua nafasi hii kuwakaribisha nyote kutumia maabara hii ambayo imesheheni na vifaa vya kisasa kwa vipimo na majaribio mbalimbali ya masuala ya ujenzi. nyote mnakaribishwa.
