Lesson 2 - Aggregates Flashcards
laboratory purpose oven specially
designed for drying, baking,
conditioning and moisture
determination.
Laboratory ovens
designed for higher temperature
heating
Muffle furnace
for accurate moisture reading on site of soil, sand, aggregates
Moisture tester
use for field determination of the
amount of surface moisture in fine
aggregates.
Chapman flasks
device for separating wanted
elements from unwanted material or
for characterizing the particle size distributions of sample.
Sieve
operated for sieves when perform
sieving tests.
Sieve shaker motor
designed the reduction of test
samples which are – for too large in
volume to be conveniently handled.
It divides samples so that half is
representative of the original whole
sample.
Sample splitters
used to determine the resistance to
abrasion and wear of cement,
concrete and similar materials.
Tribometer abrasion tester
is used for rock classification tests.
Rock classification hammer
used to determine the resistance of
aggregates by abrasion
Los-Angeles abrasion machine
It is designed for measuring the bulk density of fine powders and similar products.
Volumeter
used to determine the quality of
aggregates by abrasion
Micro-Deval testing machine
designed to reduce to powder any
sort of granulometric material (clinker, cement, stones, hard materials) for general purpose laboratory tests.
Jar Mill
designed to mix dry materials like:
powders, cement, gypsum and
granulometric materials. In a short
time it assures a perfect and
homogenous mixture.
Dry mixer
suitable to determine the abrasion
resistance of glazed tiles and other
materials
Abrasimeter
